Leadership styles in organizations during harsh economic environments

This study seeks to add to the knowledge gap on leadership styles in organizations under harsh economic environments by assessing the leadership styles of senior managers and chief executive officers in the private and public sectors and to correlate the organizational performance to the styles. A survey research design using self-administered questionnaires was used in this study. Questionnaires (150) were sent out to the major companies throughout Zimbabwe targeting senior managers and chief executive officers. Convenient sampling and snowball sampling were used to identify the organizations used in the study. Statistical Package for Social Sciences (SPSS) version 16.0 and MINITAB statistical package were used for analyzing data. Transactional leadership style was the dominant style in both the private and public sectors in the time of economic uncertainty. Contrary to widely held views, the private sector managers excelled on transactional leadership style compared to their counter parts in the public sector. The results suggest that during hard times or in economic crisis, leadership styles may change to suit the environment. In particular, transactional leadership style becomes a dominant style if organizations are to succeed in the maintenance of high standards of performance and retention of skills. In times of crisis, both transformational and transactional leadership styles are important for the survival of organizations. Although leadership styles have been studied in different organizations, information on studies in the public sector has lagged behind. The study described in the study is the first to consider leadership styles in the two sectors under harsh economic conditions (highest recorded inflation). As such, this study gives insight to managers and chief executive officers on how to keep performance high.


INTRODUCTION
"The theory of the Ecology of organisations proposes that the management team does not influence the organisation's outcomes" (Pedraja et al., 2006a).
The theory proposes that individual leaders such as the *Corresponding author.E-mail: judymwenje@gmail.com.
Authors agree that this article remain permanently open access under the terms of the Creative Commons Attribution License 4.0 International License chief executive officer (CEO) are not important in determining the performance of the organizations.Instead it is proposed that there are external determinants of the performance of an organization which are beyond the leader's control.These factors include economic conditions, market conditions, technological change and government policies (Yukl, 2002).Proponents of the theory further argue that the CEO has limited discretion to make any improvements because of internal and external constraints.The theory implies that there is a natural selection process as happens to living organisms where the environment determines which companies would survive and like in a biological system, the fit survive.Other studies however, argue stressing the importance of executives for the performance of large organizations (Yukl 2002).
This theory argues that leaders have a major influence on organizational performance and that top management team does influence certain strategic decision making and as a result influence the performance of companies.This alternative to the Ecology of organizations is called the Upper Echelons theory (Pedraja et al., 2006a).Waldman et al. (2001) proposed to include the issue of leadership style in the Upper Echelons theory because of its perceived impact on the performance of organizations.

LITERATURE REVIEW
According to Arvonen and Ekvall (1999), the field of leadership style theory has two views when it comes to defining effective leadership.The first states that there is one universal leadership style that is effective for all situations.The second view suggests that effective leadership style is contingent on the characteristics of the leadership situation (Arvonen and Ekvall, 1999;Yukl, 2002).The leadership styles that have been studied immensely in the recent literature include transformational and transactional styles.It is widely agreed that these leadership styles are better predictors of organization performance (Arvonen and Ekvall, 1999).Pedraja et al. (2006a) studied leadership styles and their effectiveness in small firms in Chile.They found that supportive leadership style was prominent and that both supportive and participative leadership styles had a positive influence on the effectiveness of small organizations (Pedraja et al., 2006a).
A decade of harsh economic conditions which prevailed in Zimbabwe between 1998 and 2008 presented an opportunity to enable an exploration of leadership styles in both the private and public sectors under an economic crisis.Public sector organizations in Zimbabwe faced increasing economic and social pressures to reform managerial and organizational practices in order to survive.The period was also characterized by a loss of skills base and a rise in the informal sector which meant many people left formal employment.According to a report in the Wikipedia (Wikipedia, 2008), unemployment in Zimbabwe reached 85% while inflation which was reported to be the highest in the world then, stood at 100 000%.There are no records describing leadership styles prevalent in either the private or public sectors in Zimbabwe.
The possible effects of styles that have been studied elsewhere on performance of Zimbabwean organizations especially during a crisis are not known.Bass (1985) indicated that transformational leadership is more likely to reflect social values and to emerge in times of distress and change while transactional leadership is more likely to be observed in a well-ordered society.Most of the studies to date have examined transformational and transactional leadership in units that operated within relatively stable conditions.It is not known if the leadership style in Zimbabwe has changed in the past decade given the distressful economic environment.Since the beginning of the economic problems in Zimbabwe a decade ago, a handful of companies have gone international and some have listed on the stock exchange signifying good performance.The present study suggests that the major variable could be leadership style.The study therefore seeks to assess the leadership styles of senior managers and chief executive officers in the two sectors and to try and correlate the organizational performance to the styles.The three leadership styles considered are transformational, transactional and laissez faire.
Transformational and transactional leadership have been used to predict unit performance (Bass and Avolio, 1994).In their study, Bass et al. (2003) found that both transformational and transactional contingent reward leadership ratings of platoon leaders and sergeants positively predicted unit performance.This was one of the few studies that have examined how transformational and transactional leadership predict performance and how each style would predict unit performance operating in challenging and uncertain conditions.Bass et al. (2003) found out that contrary to earlier research, both contingent reward and transformational leadership of the platoon leader equally predicted performance.It was concluded that transactional leadership that deals more with intrinsic motivators and recognition may overlap more with transformational leadership.The researchers further suggested that the type of transactional leadership where recognition is more individualized, may be a bridge to transformational leadership.This is in contrast to Howell and Avolio (1993), whose observation was that transformational but not transactional leadership of financial managers positively predicted unit performance over a one year period.Similar observations by Geyer and Steyrer (1998) in an evaluation of managers heading Australian branch banks, reported a stronger positive relationship between transformational leadership and long-versus short term performance.
Organizational literature on leadership theories and transformational leadership has increased in the past 20 years for the private sector.However, public sector literature has lagged behind.Researchers studying organizational leadership in the public sector, have commented on the lack of rigorous empirical examination of the proposed theories in public sector organizations (Javidan and Waldman, 2003) and pointed out several critical weaknesses of the models (Van Wart 2003).There are thus very few studies which have evaluated the role of transformational and transactional leadership styles in the public sector organizations.
However, public sector organizations are experiencing increasing economic and social pressures to reform managerial and organizational practices (Javidan and Waldman, 2003).There is pressure on the managers to pay close attention to client and employee satisfaction and at the same time consider performance outcomes.In their studies, Lowe et al. (1996) suggested that charismatic leadership was more prevalent in public sector organizations.However, their conclusions were dismissed as it was pointed out that their analysis was not representative of actual government departments.Javidan and Waldman (2003) found out that charismatic leadership was more or less conceived in public sector organizations.However, such leadership may have difficulties to produce the types of performance and motivational results associated with the private sector, because of political or bureaucratic considerations.Trottier et al. (2008) found out that employees considered transformational leadership to be more important than transactional leadership in federal or government setting.However, in the study, the federal workers ranked their leaders higher in transactional leadership factors than transformational factors.The researchers argued that government managers tend to be slightly stronger on management by exception and contingent reward and weak in instilling enthusiasm and a sense of empowerment.Trottier et al. (2008) placed individualized consideration under transactional leadership.Most studies including our current study have placed this behaviour under transformational leadership (Bass et al., 2003).Trottier et al. (2008) drew the following conclusions from their study: that good leadership seems to depend more on transformational elements than transactional.They also recommended that leaders in government settings in addition to traditional technical and managerial skills of the past, they need to be honed in transformational competencies of mission, vision and inspirational motivation.
One sector in which leadership styles, especially that of transformational and transactional styles have been discussed, is nursing management (Thyer, 2003;Murphy, 2005;Chen et al., 2005).A number of these studies have concluded that health care leadership runs under transactional style (Thyer, 2003;Murphy, 2005).Some

Mwenje and Mwenje 29
observations suggest that both transactional and autocratic styles predominate (Murphy 2005).Transformational leadership style has been recommended by several studies for the health sector.It is envisioned that transformational leadership style is ideologically suited to nurses and may ensure the future of nurses and nursing in the health care sector (Thyer, 2003).Though several observations seem to imply that transformational leadership is the preferred style for most organizations, other observations suggest that the two styles may operate together.For example, Trottier et al. (2008) suggested that both transactional and transformational leadership are perceived as important in government settings, although transformational leadership is considered more important.Geyer and Steyrer (1998) reported that transactional leadership predicted the short-term financial performance of bank branches while transformational leadership exhibited stronger predictions over a long period of time.
The current study seeks to explore the prevalence of transformational and transactional leadership styles in the private and public sectors under harsh economic conditions in Zimbabwe.Since there are no records of similar studies in Zimbabwe, the study is the first of its kind.The study does not attempt to comment on the leadership styles that may be present in retail, manufacturing and other sectors because of the limitation of sample size to make meaningful conclusions as sector specific studies have to be undertaken to draw firm conclusions.

Research questions and hypotheses
Main research question (1): Are there any differences in the leadership styles between private and public sector organizations in Zimbabwe?
Main Hypothesis 1: Leadership styles in private and public sectors are different in Zimbabwe Sub-hypothesis (i): There are differences in transformational leadership in public and private sectors Sub-hypothesis (ii): There are differences in transactional leadership between public and private sectors

Sub-hypothesis (iii):
There are difference in laissez faire leadership between public and private sectors.The three sub-hypothesis (i-iii) will be used to answer the main hypothesis Leadership styles especially transactional and transformational have been studied in several organizations.In a recent study, Trottier et al. (2008) found out that employees considered transformational leadership to be more important than transactional leadership in federal or government setting.
However, in the study, the federal workers ranked their leaders higher in transactional leadership factors than transformational factors.Burns (1978) reported that transactional leadership was predominantly found in bureaucratic organizations like government organizations.This implies that private organizations may have transformational leadership style.Other studies have suggested that leadership styles in organizations may be affected by stressful and harsh conditions.
According to Bass et al. (2003) the maintenance of high standards of performance under challenging environments requires both transformational and transactional leadership styles.The harsh economic conditions in Zimbabwe present us with an opportunity to study leadership style in organizations in Zimbabwe.The items that will be used to measure this hypothesis are questions 6 to 11 for transactional leadership, questions 13 to 23 for transformational leadership and questions 24 to 28 for laissez faire leadership style.

Research question 2
Is there a single or dominant leadership style that could be associated with public or private sector organizations in Zimbabwe?Hypothesis 2: Transactional leadership is the dominant leadership style in public sector organizations Burns (1978) reported that transactional leadership was predominantly found in bureaucratic organizations like government settings.Many studies especially in nursing institutions have reported the prevalence of transactional leadership in the nursing institutions and have pointed the need for transformational leadership (Murphy, 2005;Thyer, 2003).Given the earlier mentioned sentiments, transactional leadership is expected to be the dominant leadership in public sector organizations.In order to measure transactional and transformational leadership, the questions 6-11 and 13-23 were used respectively.The combined means for the items were compared using t-test.

Research question 3
Is there are particular leadership style that could be associated with good organizational performance under harsh economic environment in Zimbabwe Hypothesis 3: Organizations in which transformational leadership is the dominant style perform better than those where transactional dominate.
Hypothesis 4: Are the leadership styles that are associated with good performance in the public sector the same as those in the private sector?Hypothesis 5: Do organizations having a greater diversity of leadership styles in the organization perform better than those that have low diversity of leadership styles.
A number of studies have attempted to correlate leadership style and the performance of organizations (Evkall and Ryhammar, 1997;Pedraja et al., 2006b;Bass et al., 2003).Berson and Linton (2005) found that transformational leadership more than transactional contingent reward leadership, supported the development of quality environment.Studies by Pedraja et al. (2006b) with small firms in Chile showed a positive influence on the effectiveness of the firm in the case of transformational leadership while negative effect was seen in the case of transactional and laissez faire leadership.
A review by Elkins and Keller (2003) suggested that "transformational leadership" appears to be an effective style for use in Research and Development (R&D) settings.
Certain behaviours of transformational leadership which included mission awareness were important in predicting the success of R&D projects (Pinto and Slevin, 1989).
However, in recent studies by Berson and Linton (2005) on the role of leadership style in R&D and administrative environments, it was concluded that both transformational leadership and transactional contingentreward leadership were related to the establishment of quality environment in the R&D part of telecommunications firm.
Contrary to earlier research, Bass et al. (2003) found out that both contingent reward and transformational leadership of the platoon leader equally predicted performance.It was concluded that there could be an overlapping of transactional leadership and transformational leadership.The aforementioned observations are at variance with observations by Howell and Avolio (1993), who noted that transformational but not transactional leadership of financial managers positively predicted unit performance over a one year period.The questions from the questionnaire that have been used to assess both transformational and transactional leadership style will be used.Performance questions (29, 37, 38 and 41) from the questionnaire will be used.The concept of profit was not considered as there were not for profit organizations.Some of the questions helped to clarify the main questions.

Research question 4
Does leadership style have a greater influence on the performance of an organization than political and economic variables?

Hypothesis 6
The performance of organizations in Zimbabwe is attributed to leadership styles than political and economic variables.The literature cited earlier has indicated that leadership style plays an important role in the performance of organizations.Bass (1985) argues that "transformational leadership energizes groups to persist when conditions are unpredictable, difficult, and stressful".Since the economic environment in Zimbabwe over the past ten years has been difficult, any good performance by organizations may be attributed to leadership styles.Performance items (29, 37, 38, 40 and 41) were be used to establish the relationship between leadership styles and the performance of organizations in Zimbabwe.Analysis will involve stepwise regression analysis of each performance item carried out against the three leadership styles (transactional, transformational and laissez faire).

Research design
A survey research using a self-completion questionnaire also called a self-administered questionnaire was used in this study to gather information on leadership style from organizations.In studies to assess leadership styles, several methods have been used by a number of researchers.Shea (1999) studying the effect of leadership style on follower's performance improvement on a manufacturing task over time, utilized an experimental methodology.The experiment used students who were randomly assigned to one of three leadership conditions.
In a study to predict unit performance by assessing transformational and transactional leadership, Bass et al, (2003) used direct observations and field observations in their study.The commonest method that has been used in the assessment of leadership styles have been surveys (Pedraja et al., 2006a;Arvonen and Ekvall 1999;Waldman et al., 2001).
A survey research design using self-administered questionnaires was used in this study because the method is cheaper and easier to administer and to collect data (Bryman and Bell, 2003;Bryman, 2012).It requires the respondents to read the instructions and write or mark their responses to the questions.In the present study the sample was geographically widely dispersed as organizations across the country were considered.The questionnaires were posted electronically and physically which made it cheaper and quicker.The method has also the advantage of convenience for respondents as they are able to complete a questionnaire at a time when they want and also at their own speed (Bryman and Bell, 2003).This was especially relevant in this study as Senior Managers and Chief executive officers are very busy people and are hard to pin down for an interview.

Population and sampling plan
The target population for the survey was senior managers and Chief executive officers of organizations in Zimbabwe.The organizations considered were medium to large organizations with at least 60 employees.This is because the size of the organization has been noted to have an effect on the leadership style that could be practiced (Pedraja et al., 2006a).
The organizations considered had to be based in Zimbabwe and were mainly located in any of the cities in Zimbabwe.A number of organizations have closed down business in Zimbabwe especially in Bulawayo (area where researchers are based) due to the adverse economic environment hence the need to extend the research beyond Bulawayo (research base).In order to make the follow up process easier and manageable, most of the government departments targeted were from Bulawayo.The sample consisted of private sector and public sector companies.The researchers felt that with the time and cost constraints of the project, a sample consisting of a survey population of 150 organizations would be representative.A consideration of the fact that managers are busy people and hence this might affect the response rate was taken into account.Attempts were made to ensure that at least a sector got 40% of the questionnaires.
Non-probability sampling methods were used as the sampling technique as it was initially impossible to verify which organizations were still operational and also whether the senior managers were in the country during the period.The technique was also used because it was impossible to ascertain the number of organizations present in Zimbabwe.Convenient sampling and snowball sampling were used to identify the organizations used in the study.Convenient sampling was used because the researchers had access to some senior managers who attended a Master's in Business Administration degree class at the National University of science and Technology.Researchers also made use of other national events such as The Zimbabwe International Trade Fair (ZITF, 2008) or other religious and social functions.The above strategies ensured that the questionnaires would be returned.
The snowball sampling technique was also used in this study as the researchers contacted a few senior managers and used these managers to get contact of other senior managers.The other senior managers even volunteered to pass the questionnaire to their colleagues in other organizations.
The technique was an inexpensive way to enlarge the sample size.

Questionnaire design and measures
A review of the literature revealed several instruments used to assess leadership style especially transformational and transactional leadership styles.The commonest of these instruments that has been used by a variety of researchers in the field of leadership, is the Multifactor Leadership Questionnaire (MLQ) which was originally developed by Bass (1985) and updated by Bass and Avolio (1990).
An attempt to get the instrument from the authors was fruitless as the instrument has now been commercialized although there is a claim that it can be made available for research purposes.The instrument is available at a cost of US$ 30 which expense was beyond the project.The researcher then decided to design a new questionnaire that would encompass the behavioural and personal attributes of transformational, transactional and laissez-faire leadership style.Development of the instrument considered the hypotheses and sub-themes of the project as well as using literature were the MLQ had been used (Bass and Avolio (1990).
The wording of the questions was very simple and easy to understand so as to improve the response rate especially for senior managers and Chief executive officers who are very busy people.The preamble outlined the purpose of the survey as well as the researchers' contact details for clarifications.The questionnaire contained mostly closed ended questions that required ticking to make it easier to respond.A few open ended questions were used to solicit for more information.Section A of the questionnaire covered fairly general questions on gender, position in the organization and the type of business and sector the organization was involved in.Section B assessed the three leadership styles namely transactional, transformational and laissez-faire.The last part of the questionnaire which is section C, covered questions on the performance of the organizations measured by expansion geographically, profits, customers and employee satisfaction amongst other things.
A five point scale was used in most cases and respondents were required to report the degree to which they agreed with each statement.Possible responses ranged from "strongly agree" to strongly disagree".The items measuring transactional leadership in Section B were based on the work by Pedraja et al. (2006a) and on Bass (1985) revised full range model of leadership.Items 6 through to 11 assessed transactional leadership.According to Bass's revised full range Model of leadership, transactional leadership only intervenes when standards are not met.This is also termed management by exception, passive.Item 6 which asked if action is taken when mistakes are made measures this aspect of leadership.Items 7, 8 and 11 clarify what needs to be done and material rewards for services rendered.These questions answer one characteristic of transactional leadership which is the issue of contingent reward.The other items 9 and 10 assess management by exception, active which is a characteristic of transactional leadership.Item 9 assesses whether leadership focuses attention on any irregularities while item 10 assesses whether any deviations from the expected is given attention.
Transformational leadership was assessed by item 13 through to 23.The items 13-16 assessed inspirational motivation which is one characteristic of transformational leadership.
Items 17-20 measured idealized influence which involves the ability of leadership to become a source of inspiration, be role model, enhance follower pride, generate loyalty from followers and give them confidence.Item 21 which asked if leadership diagnoses and elevates the needs of each employer, measured individualized consideration which is a major characteristic of transformational leadership.Items 22 to 23 assessed the stimulation of followers by leadership through determination and also by enabling them to perceive the world from new perspectives by questioning old beliefs.
Laissez-faire leadership style was assessed by items 24 to 28.The questions assessed a general lack of intervention or acceptance of responsibility by leadership.As mentioned before, questions 29 to 42 assessed organizational performance.

Pre-testing questionnaire
For testing of the questionnaire, a convenient sample of 10 senior managers was taken.The pre-test was carried out to find out if the questionnaire could be understood and if there were any issues that required clarification.After the pre-testing, an additional four (4) questions were added to the questionnaire which initially had thirty eight questions.The four questions that were added are 4, 15, 21 and 31.The original questionnaire had only differentiated the type of businesses being run, however, the addition of question four categorized the businesses into two main sectors public and private sectors.Questions 15 and 21 where additional questions on transformational leadership these questions reinforced the idea of vision and individualized consideration.The addition of question 31 was important as other organizations are not profit making.Questions 34, 35, and 36 were modified to include services.This was in response to some organization which did not have sales but services.The questionnaire became clearer and more reliable with the indicated additions.

Validity and reliability of variables and measures
In order to assess the validity and reliability of the variables of transformational, transactional, laissez faire and performance measurements, Cronbach's alpha was calculated using SPSS (version 16).The items selected should be reliable and the multiple items selected to measure the same concept should have internal consistency.An alpha value should preferably be above 0.700.The alpha values for transactional and transformational leadership and performance exceeded 0.700.However, alpha value for laissez faire was slightly below 0.700 with a value of 0.696.This is not uncommon as in literature alpha values of less than 0.700 have been used in concepts of management (Trottier et al., 2008).Transformational leadership style was measured by 11 items on the questionnaire (13 to 23) and gave a relatively high level of internal reliability (Cronbach's alpha = 0.897).Six items from the questionnaire (6 to 11) were used to measure transactional leadership style.A test of internal reliability showed that the index variable was relatively reliable to measure transactional leadership (Cronbach's alpha =0.734).Eight items (29, 32, 34, 37, 38, 39, 40 and 41) were used to measure performance and gave a good internal reliability (Cronbach's alpha = 0.837).

Data collection and response rate
One hundred and fifty questionnaires were sent out to top management of corporations in Zimbabwe for both public and private sectors.A total of 71 completed questionnaires were received giving a response rate of 47%.However, 66 completed questionnaires were used in the analysis given that three of them had been completed by junior-managers, one questionnaire arrived late while the other was incompletely filled in.Thirty public sector organizations, thirty three private sector organizations and others (NGOs and Churches) were evaluated in the study.

Data analysis
The data was coded, inputted and analyzed using the Statistical Package for Social Sciences (SPSS) version 16.0 and MINITAB statistical package.Several demographic data were analyzed through descriptive statistics in SPSS.In order to assess the leadership styles present in the organizations, the means of the items comprising each leadership style were calculated in SPSS.The means were compared for significance at 0.05 level using ttest.A paired sample t-test was also used to determine the dominant leadership style in either private or public sectors.Similar test was used by Trottier et al. (2008) to compare transactional and transformational leadership.A null hypothesis was formulated which stated that there was no relationship between the variables.Regression analysis was carried out using MINITAB to measure the relationship between leadership style and performance.The R 2 (Rsquared) values were calculated to measure the contribution of the variable to the variation in performance.The significance of the relationship between each leadership style to performance was assessed at 5%.

Main research question 1
Are there any differences in the leadership styles between private and public sector organizations in Zimbabwe?

Main Hypothesis 1
Leadership styles in private and public sectors are different in Zimbabwe Sub-hypothesis (i): There are differences in transformational leadership in public and private sectors Sub-hypothesis (ii): There are differences in transactional leadership between public and private sectors Sub-hypothesis (iii): There are difference in laissez faire leadership between public and private sectors Three leadership styles namely transactional, transformational and laissez faire were assessed in public and private sector organizations in Zimbabwe using the constructs for each leadership style; transactional leadership style (questions 6 to 11), transformational leadership style (questions 13-23) and laissez faire leadership style (questions 24 to 28).Means and standard deviations were generated for each of the leadership styles against each sector as shown in Tables 1 to 3. Transformational leadership was compared between the sectors using questions 13-23 from the questionnaire and the means are as shown in Table 1.
The results shown in Table 1 from the comparison of the means for each sector using constructs for measuring transformational leadership show that transformational leadership style to be present in both the private and public sector organizations in Zimbabwe.The questions 13 to 16 which measure "inspirational motivation" which is one characteristic of transformational leadership was practiced more by public sector organizations compared to private sector organizations.This was unexpected as leadership in private organizations is the one that is supposed to excel on "inspirational motivation".Questions 17 to 23 which addressed the remaining three "Is" of transformational leadership namely "idealised influence" (questions 17 to 20), "individualised consideration"(question 21) and "intellectual stimulation" (questions 22 to 23) were practiced more in the private sector than in the public sector organizations as indicated by the means.
The results show that concerning the diversity of aspects of transformational leadership, the private sector managers excel in transformational leadership in comparison to their counter parts in the public sector organizations.The means however, show that transformational leadership style is present in the two sectors.However, there is need to assess if there are any differences in transformational leadership style between the two sectors.
A comparison of means of transformational leadership style in each sector was carried out using paired-samples T-Test and results are shown in Table 2.The t-ratio is less than 1.96 and the p-value > 0.05 therefore the differences between transformational leadership in the public and private sectors is not significant.The mean for private sector (2.2348) being less than that of the public Mwenje and Mwenje 33 sector (2.3492) suggesting that private sector managers excel in transformational leadership than their private counter parts.
Literature has nearly maintained that transformational leadership is more in private organizations than in public sectors or government organizations.This has also been used to explain the poor performance of most public sector organizations.However, application of statistical significance show that there are no significant differences in transformational leadership between public and private sector using the sample studied (t = 1.0840, p = 0.304).
Therefore we accept the null hypothesis that there are no differences in transformational leadership style between public and private sector organizations in Zimbabwe.The means in Table 3 show that transactional leadership is present in both the private sector and public sector organizations in Zimbabwe.Question 6 measures management by exception, passive and was found to be practiced more in the public sector than in the private sector.
This observation is consistent with literature where managers only take action when mistakes are made.The rest of the questions (7 to 11) showed that private sector managers excelled more in the activities than their public sector counter parts.Items 7, 8 and 11 clarify what needs to be done and material rewards for services rendered (mean the characteristic called contingent reward).
The private managers also excelled in management by exception, active where performance of employees was monitored and corrective action taken (questions 9 and 10).The next stage was to find out if there were any significant differences between the means for transactional leadership style between public and private sector organizations in Zimbabwe.
ere are significant differences in transactional leadership style between the private sector and public sector organizations in Zimbabwe since t-ratio is greater than 1.96 and p-value< 0.05.Therefore we reject the null hypothesis and accept the sub hypothesis (ii) because private and public sector organizations differ.The earlier shown results which show private sector managers to be high in transactional leadership than public sector managers are very interesting and at variance with observations in literature.In a study that examined the nature and significance of leadership in government settings, government workers ranked their leaders higher in transactional leadership factors than in transformational factors (Trottier et al., 2008).Hence public sector managers have been evaluated as better transactional leaders (Trottier et al., 2008).
The means of questions used to measure laissez faire leadership style are very close to 3.00 for the two sectors.This implies that there is very little laissez faire leadership style in both the private and public sectors in Zimbabwe.Comparisons of the means using paired sample T-test is given in Table 6 to find if the differences in the observations between the two sectors concerning laissez Note: All items were measured on a five point scale ranging from 1 = "strongly agree" to 5 = strongly disagree.faire style are significant are shown below.The means for the for private and public sector are very close and above 3.00 signifying that there is very little of laissez faire leadership style in the two sectors.In the questionnaire 3.0 indicated occasionally true while 4.0 meant never true in other words there would be no laissez faire style.
There are no significant differences since the t-ratio is less than 1.96 and the p value > 0.05.Note: All items were measured on a five point scale ranging from 1 = "strongly agree" to 5 = strongly disagree.We accept the null hypothesis that there are no differences in laissez-faire leadership between the two sectors.The three sub hypothesis help us to answer the main hypothesis of the study (Hypothesis 1) which says Leadership styles in private and public sectors are different in Zimbabwe.We agree with the hypothesis and reject the null hypothesis.This is because transactional leadership style differs in public and private sector organizations.
A summary of results for research question 1 (Table 1  and 3) show that transactional and transformational leadership styles are present in both private and public sector organizations in Zimbabwe.However, Table 5 shows that laissez faire leadership style is infrequent in the two sectors.
The results (Table 2) also show that there is no significant differences between transformational leadership style in the public and private sectors as a paired sample t-test showed that the difference is statistically insignificant at 0.05 level (t = 1.084, p = 0.304).However, the mean for private sector (mean = 2.2348) was lower than the mean for public sector organizations (mean = 2.3492) indicating that they excelled more in transformational leadership competencies than their counter parts in the public sector (Table 2).Based on the results in this study (Table 4), a paired sample t-test shows that the differences between private and public sector in transactional leadership style is significant at the 0.05 level (t = 4.939, p = 0.004).The results indicate that private sector managers excel in transactional leadership (mean = 1.9495) in comparison to public managers (mean = 2.2055).Therefore, we reject the null hypothesis which says there are no differences in leadership style between the private and public sector organizations.We accept the alternative hypothesis and say there are differences in leadership styles between the private and public sector organizations especially in transactional leadership.The private sector managers seem to excel in transactional leadership style under the present conditions than their counter parts in the public sector.These results are interesting as they are at variance with observations in other studies.

Research question 2
Is there a single or dominant leadership style that could be associated with public or private sector organizations in Zimbabwe?

Hypothesis 2
Transactional leadership is the dominant leadership style in public sector organizations.The mean for transactional leadership in public organizations is 2.2055 while that for transformational leadership in the same sector is 2.3492 (Table 7).These mean values may not be significantly different however; the lower value mean for transactional leadership style suggests that transactional leadership style is the dominant leadership style in public sector organizations.This is agrees with observations from other studies.Table 12 also shows as mentioned before that managers of private sectors excel in transactional leadership and that it is also the dominant leadership style in private organizations in Zimbabwe.Laissez faire leadership style is infrequent in both organizations.
However, the means show that it is more in public sector compared to the private sector organizations.In answer to the question of a dominant leadership style that could be associated with public or private sector organizations; the results indicate that transactional leadership style is dominant in all sectors.However, both transformational and transactional leadership styles are present in both private and public sector organizations.We therefore reject the null hypothesis and accept that Transactional leadership is the dominant leadership style in public organizations.Our results when considering the means of the items comprising transactional leadership shows that the public sector excel in management by exception, passive.This trend has been seen in other studies as discussed below.
According to Burns (1978cited in Thyer 2003:74) The aspect that contributed highly to transactional leadership style was management by exception, passive (measured by question 6 on questionnaire).This means that managers of public organizations only take action when mistakes are made rather than being pro-active.However, it was unexpected that transactional leadership be found in higher levels in private sector compared to public sector organizations.The reasons for this could be that the items of contingent rewards where managers of private companies excelled in this study are important in harsh environments.In order to motivate workers in stressful environments, rewards play a major role.The presence of both leadership styles in the two sectors supports recent observations.
Most researchers now agree that both transactional leadership and transformational leadership elements are important for leadership effectiveness in all organizations (Trottier et al. 2008;Murphy, 2005;Bass et al., 2003).A number of studies especially in the nursing profession (government setting) have advocated for transformational leadership as the panacea for leadership problems in that profession (Murphy 2003:131, Thyer 2003: 73 to 74).Transformational leadership has been observed to have a cascading effect in that the behaviours practised at the top level of organizations is mirrored downwards through the organizational ladder (Murphy 2005:131).Our results suggest that both leadership styles are important in the two business sectors.Lindholm et al. (2000) argues that organizations require latitude, and that diverse leadership styles are important at different times in organizations.The best performance therefore is the result of a balance between transactional and transformational leadership behaviours (Trottier, 2008;Stordeur et al., 2001;Murphy, 2005).According to Stordeur et al. (2001) transformational leadership is not a substitute of transactional but that it complements and enhances it.
Objective 2: To find out if the companies that are performing well under the current harsh economic conditions in Zimbabwe have a dominant leadership style

Research Question 3
Is there are particular leadership style that could be associated with good organizational performance under harsh economic environment in Zimbabwe Hypothesis 3 Organizations in which transformational leadership is the dominant style perform better than those where transactional dominate.

Hypothesis 4
Are the leadership styles that are associated with good performance in the public sector the same as those in the private sector?Hypothesis 5 Do organizations having a greater diversity of leadership styles in the organization, perform better than those that have low diversity of leadership styles.
In order to find out a particular leadership style that could be associated with good organizational performance, transactional and transformational leadership styles of those companies that were performing well were assessed.
The following dimensions of performance were used as they have been used in many studies and were easy to analyse: Qn 37 How would you rate the satisfaction of your customers?Qn 38 How would you rate the satisfaction of your personnel?Qn 41 Your organization is growing The concept of profit was not considered at this juncture as there were non-profit organizations.When question 37 was assessed concerning the satisfaction of customers, there were no differences in either transactional leadership or transformational leadership between the organizations with satisfied customers and those with non-satisfied customers.Here are significant differences in transactional leadership styles between managers of satisfied employees and those employees that are not satisfied (p< 0.05).Transactional leadership style of top management of organizations with satisfied personnel (mean = 1.6964) excelled in transactional leadership compared to their counter parts in organizations were the personnel were not satisfied (mean = 2.3153) Table 8.
There are significant differences in transformational leadership styles between managers of satisfied personnel or employees (mean = 1.8413) and those that are not satisfied (mean = 2.5479) (p< 0.05).The results indicate that managers of satisfied personnel or employees were stronger in transformational leadership style than their counter parts with unsatisfied employees.
Employee satisfaction has been associated with transformational leadership style, and Bass (1985) argues that transformational leadership energizes groups to persist when conditions are unpredictable, difficult and stressful.Of the four "Is" of transformational leadership, our results (Table 9) showed that the evaluated managers excelled in idealized influence, individual consideration and intellectual stimulation.The aspects of intellectual stimulation and individualized consideration are important for employee satisfaction.Bass et al. (2003) suggests that the maintaining of high standards of performance against challenging environments requires both transformational and transactional leadership.
This may be the situation in Zimbabwe where organizations have faced incessant economic hardships over a decade.The fact that managers of satisfied employees excelled in both transactional and trans-  Stordeur et al. (2000).They found that transactional leadership style could offer prompt solutions for immediate staff needs, particularly under stressful conditions.This would result in the satisfaction of personnel.
There are no significant differences between transactional leadership style between managers whose organizations are showing growth and those whose organizations are not growing (p > 0.05) in Table 10.The means are very close.Results of means in Table 11 consistently show that for organizations that are growing, the managers excel in transformational leadership than their organizations which again excelled in the two leadership styles, performed well.Bass et al. (2003) stresses the importance of diversity in leadership style in order to maintain high performance standards especially under counter parts in organizations that are not growing.
Here are significant differences in the means in transformational leadership style of the organizations that are growing and those that are not growing (p < 0.05).The means above show that the managers whose organizations are growing excel in transformational leadership (mean = 2.0656) than those whose organizations are not growing (mean = 2.6455).Observations in the current study have indicated that both transformational and transactional leadership styles are important for the performance of organizations in Zimbabwe.However, those organizations that excelled in transformational leadership showed higher performance indicated by growth and personnel satisfaction.Many organizations in Zimbabwe that have grown and expanded have been characterized by transformational leadership at the top level.
While the economic environment has been adverse to business growth, many of the transformational leaders have channelled and painted a new picture and made employees see a new perspective.
Organizations such as Africa sun and Econet have gone international to mention a few.Local papers have attributed this to the charismatic or transformational nature of the top leadership.Bass et al. (2003) showed that transformational leaders work more effectively in rapidly, changing environments by putting challenges into perspective and then appropriately responding to those challenges.From the aforementioned observations, it can be concluded that transformational leadership style could be associated with good organizational performance under harsh economic environment in Zimbabwe (Research question 3).We thus accept hypothesis 3, that organizations in which transformational leadership is the dominant style perform better than those where transactional dominate.Hypotheses 4 has been answered in the fact that the current study has shown that companies in either public or private which would excel in both transactional and transformational resulted in good performance.
The present study reveals that there is no organization from the samples considered with one type of leadership style hence Hypothesis 5 is answered in that all stressful conditions.
Objective 3: To establish if there is a relationship between leadership styles and performance of organizations in Zimbabwe

Research question 4
Does leadership style have a greater influence on the performance of an organization than political and economic variables?

Hypothesis 6
The performance of organizations in Zimbabwe is attributed to leadership styles than political and economic variables.
The following performance items from the questionnaire were used to establish the relationship between leadership styles and performance of organizations in Zimbabwe: Qn 34 In the last 5 years, your sales or services have?Qn 37 How would you rate the satisfaction of your customers?Qn 38 How would you rate the satisfaction of your Stepwise regression analysis of each performance item was carried out against the three leadership styles (transactional, transformational and laissez faire leadership style) to choose the best predictor that explains performance.There is a significant relationship (p-value=0.001<0.05) between transformational leadership style and performance.Transformational leadership style accounts for 98.1% (R2) of the variation in performance (Q34) as shown in Table 13a.There is a significant relationship (p-value=0.001<0.05) between transactional leadership style and performance.Transactional leadership style accounts for 96.4% (R2) of the variation in performance as measured by increase in sales or services (Table 13b).
Transactional leadership style was chosen ahead of the other two styles as the best predictor of performance in stepwise regression using question 37 on customer satisfaction.Table 18 shows the results.The results in Table 14a show a significant relationship (p-value=0.001<0.05) between transactional leadership style and performance.Transactional leadership style account for 98.4% (R2) of the variation in performance (Q37).Transformational leadership style was also chosen as the best alternative variable in explaining performance.There is a significant relationship (p-value=0.005<0.05) between transformational leadership style and performance.
Table 14b shows the transformational leadership style accounted for 95.1% (R2) of the variation in performance as measured by customer satisfaction.There is a significant relationship (p-value=0.008< 0.05) between transactional leadership style and performance.Transactional leadership style accounted for 93.1% (R2) of the variation in performance as measured by personnel satisfaction (Table 15a).Transformational leadership style was the best alternative predictor of performance.There is a significant relationship (p-value=0.015<0.05) between transformational leadership style and performance.Transformational leadership style accounted for 89.7% of the variation in performance as measured by personnel satisfaction (Table 15b).
There is a significant relationship (p-value=0.006<0.05) between transformational and laissez faire leadership style and performance.Table 16 shows that the two leadership styles account for 99.4% (R2) of the variation in performance as measured by organizational image.There is a significant relationship (p-value=0.006<0.05) between transactional and laissez faire leadership style and performance.The two leadership styles account for 99.6% (R2) of the variation in performance as measured by relative position of organization in the industry (Table17).
Stepwise regression analysis carried out against the three leadership styles (transactional, transformational and laissez faire leadership style) to choose the best predictor that explains performance as measured by growth of the organization (Qn 41) identified transformational leadership.From the stepwise regression below it can be noted that transformational leadership style account for about 97.3% of the variation in performance.The addition of laissez faire increased the R-square value by about 3% thus increasing the explanatory power of the model.Since the p-value (0.000) is less than 0.05 (Table 18a, b), we conclude that the regression model is significant at the 5% level of significance.We conclude that explanatory variables transformational leadership and laissez faire account for 100% of variability in the response variable performance (growth).We note that transformational leadership style contribute positively to performance whereas laissez faire contributes negatively, implying that a unit increase in transformational leadership style will result in the increase in performance whereas a unit increase in laissez faire leadership style will decrease performance.
The p-value (0.007) is less than 0.05 implying that the model is significant at the 5% level of significance.The regression equation indicates that transaction leadership style contributes positively to performance.The explanatory power of the model is 93.8% which imply a very good model though the explanatory power is less than that of transformational leadership style.
The aforementioned results show that there is a relationship between leadership styles and the performance of organizations in Zimbabwe.Furthermore, leadership styles seem to have greater influences on performance than political and economic variables given the high percentage contribution to the variation by the items used to measure performance.
In a study of transformational and transactional leadership in small companies in Chile, Pedraja et al. (2006b) showed that leadership style influences the effectiveness of the small companies studied.They found that the influence was positive for transformational leadership while it was negative in the case of transactional and laissez faire leadership (Pedraja, 2006b).Despite the increase in literature on transformational and transactional leadership, there are only a handful of studies that have examined how transformational and transactional leadership predict performance (Bass et al. 2003:207).
In recent studies, both transformational and transactional contingent reward leadership of leaders in the army predicted unit performance (Bass et al., 2003).They confirmed that transformational leadership augmented transactional leadership in predicting performance.The results also suggest that the performance of organizations in Zimbabwe may be attributed to leadership style.However, this is not to say that other factors are not at play.The results indicate that both transformational and transactional leadership

Conclusions
The major objective of this research was to find out the leadership styles prevalent in the public and private sector organizations in Zimbabwe.The focus was then to find out which leadership styles were dominant in the private and public sector.The study also wanted to find out if the performance of organizations could be explained by leadership styles and which styles were associated with good performance.Finally, the research wanted to add to the body of knowledge in this area since it is scant or non -existent in Zimbabwe.There has been a limited body of knowledge in the area of leadership style especially transactional and transformational leadership styles in Zimbabwe.The research has indeed contributed to the understanding of leadership styles prevalent in private sector and public sector organizations in Zimbabwe.There are several conclusions that have emerged from the current study and they are as follows: 1.The research questions aimed at finding out the leadership styles that are present in Zimbabwean organizations and if there were any differences in leadership styles between private and public sector organizations.
Transformational and transactional leadership styles are present in both private and public sector organizations in Zimbabwe.2. Laissez-faire leadership style is infrequent in the organizations that were considered in the current study 3. Private sector organization managers excelled in transactional leadership and were surpassed by public sector managers on one factor of transactional leadership which is management by exception, passive.The private sector managers were stronger on contingent rewards more than their counter parts in the public sector.This observation was at variance with literature which normally shows public sector managers to excel in transactional factors including contingent rewards.However, harsh economic conditions may be responsible for such an  : 3;198.7;66.2 Total: 4;3222.8The regression equation is perf-Q41 = 9.32 + 0.346 transact.observation were the private sector organizations would come high on rewards to cushion employees against the adverse environment.4. The differences in transformational leadership styles between private sector organizations and public organizations were not significant.However, private sector managers excelled in three "Is" out of the four factors of transformational leadership.They excelled in idealized influence, intellectual stimulation and individual consideration compared to their counter parts in the public sector.The observation that transformational leaders were low on inspiration motivation compared to public sector managers is unexpected. 5.Under the current adverse economic conditions in Zimbabwe transactional leadership style rather transformational was found to be the dominant leadership style in both the private and public sector organizations.In literature, the private sector is expected to have transformational leadership as the dominant leadership style while transactional leadership should dominate and be associated with government organizations.6.There is no single leadership style that could be associated with either the public or private sector organizations but that both were present in different levels.This observation is supported by recent literature which recognises the importance of the two leadership styles.Bass's full leadership range model is the proponent of this observation.They argue that the two styles are a continuum rather than isolated and distinct.7. Leadership styles especially transformational and transactional had a positive influence on performance while laissez-faire leadership style had a negative impact on the performance of organizations.8.There is a strong relationship between leadership style and the performance of organizations in Zimbabwe.Leaders that excelled in transformational leadership style had organizations that showed growth and employee satisfaction.Therefore leadership style may have a greater effect on performance of companies than economic and political variables.
The major objectives of the study which were to find the predominant leadership styles in the corporate organizations in Zimbabwe were met.The study also established the dominant leadership styles in the private and public sector organizations.
The relationship between leadership style and the performance of organizations was confirmed.The present study has significantly added to knowledge especially on leadership styles in organizations under stressful and harsh economic environments.
The present study has made important contributions to leadership styles in the private and public sector organizations.The uniqueness of the study is that leadership style and performance was considered under stressful and harsh economic conditions.Few studies have taken these aspects into consideration and indeed the results point to a different pattern than that observedin normal environments.
Literature on leadership in public sector organizations has lagged behind.This study has added important insights to the body of knowledge on leadership in public organizations.

RECOMMENDATIONS
As a result of the conclusions earlier mentioned, the following recommendations are made: 1. Managers should be trained on the benefits of transactional and transformational leadership styles and how to match them for different situations.2. Since leadership style has such a bearing on performance, management courses including MBA programs should have a larger leadership component.3. Government should advocate for regular training of top management on leadership issues to ensure that they keep abreast with current trends and economic environment.4. Organisations should have in house training programs for all managers specifically tailor made for their industry.5. Confederation of Zimbabwe Industries (CZI) should establish a business forum where CEOs and Senior Managers interact and share ideas with regards to leadership and performance

LIMITATIONS
Due to the harsh economic period that prevailed the quality of the sample may have been compromised as most skilled top management left the country for greener pastures.So it is possible that some of the ideal leaders who would have been suitable to be part of the sample left the country.The research was conducted in only two cities within an African context, any interpretation or generalization should allow for possible cultural bias.Given the harsh economic conditions it was difficult to ensure that one gets more than one respondent per organization.As a result the study treated a single respondent to represent the leadership style prevalent in that organization.

AREAS FOR FURTHER RESEARCH
This study has opened up several areas for future research.Further studies and research in the areas listed below will add to the body of knowledge on leadership and performance.
1. Time, resources and project space did not allow further investigations of how other variables such as age, sex, culture and level of education would affect leadership style and performance.These are potential areas for further research.2. It will also be interesting to find out how subordinates rate their managers on leadership style.This is because senior managers may have a bias on themselves.3. Research is needed to determine the impact or influence of company Boards on the leadership style and performance of organizations.4. A study that concentrates on the leadership style of the CEOs and the influence on performance is essential.5.The current study grouped all industries together.There is a need to find out the leadership styles in different industries or sectors such as service industries, manufacturing industries, banking sectors and education.6. Research on a similar line as the current study should be carried out on parastatal organizations and compare them with private and wholly government organizations.
