ABSTRACT
The study examined the influence of leadership practices on productivity of academic staff in
polytechnics in Nigeria. The co relational study involved 285 respondents from six polytechnics.
Data were collected using a self-administered a questionnaire which validity the reliability was
confirmed through Factor Analysis and Cronbach Alpha test. The constructs of leadership
practices were examined. Descriptive analysis involved the use of means, while multiple
regressions were used to test the hypotheses. The results revealed that transformational
leadership was a positive significant predictor of academic staff productivity. This led to the
conclusion that transformational leadership was an important factor for enhancing staff
productivity. Therefore, it was recommended that managers of organisations such as
polytechnics should emphasise the transformational leadership practice in providing leadership
to the institution.
Key Words: academic staff, leadership practices, polytechnic, productivity, transactional,

INTRODUCTION
Workforce productivity remains a primary element for success in most organisations (Haenisch,
2012). Workforce productivity is the output per employee hour and quality considered (Leblebici,
2012). Productivity is efficiency in production, This actually represents how much output an
individual or organisation obtains from a given set of inputs. Productivity is typically understood
to be an output–input-ratio. Employee productivity is important for the successful performance
of organisations in way that that it leads to accomplishing of organisational goals and objectives
(Raza, Anjum and Zia 2014), effective performance of tasks (Yukl, 2008), efficient use of
resources (Rahman and Rahman, 2009), quality of output, workmanship, adherence to standards,
and customer satisfaction (Ayinde, 2014). In organisations such as polytechnics, academic staff
productivity is considered in terms of teaching, preparing for class, research and scholarly
activities, student research supervision, supervising internship, working with students on

activities other than coursework, interacting with students outside classroom, innovation and
conducting community service activities (Sullivan, Mackie, Massy & Sinha, 2012).According to
Meyer (1998), faculty workload is calculated by three measures, namely the total number of
hours each week that faculty work to meet their job responsibilities, the weekly number of hours
spent in instructional activities, and the weekly number of hours spent on scholarly activities.
Anumaka and Ssemugenyi ( 2013), Reed, Enders, Lindor, McClees and Lindor (2011), Oyekan,
(2014), Wamala and Ssembatya ( 2015) and many others, have carried out studies on employee
productivity to establish its correlates. However, as those studies suggest, there has been a bias
of those studies towards universities, thus excluding the polytechnics context. This research
examined the productivity of academic staff in polytechnics in Nigeria .It was therefore carried
out with the purpose of linking productivity with the leadership practices in the polytechnics and
not universities.
Leadership theories-transactional and transformational leadership theories, suggested some
variables of leadership practices which relate to employee productivity. The transformational
theory suggests that transforming leadership is a relationship of mutual stimulation and elevation
It has been observed that a leader might transform subordinates interest and at the same time
motivate his followers or subordinates in order to achieve greater goals and higher productivity
in any organization. Bolden (2003), explained that transactional leadership is an emphasis on the
importance of relationship between the head and the subordinates and usually focusing on
mutual benefits. This relationship might result into rewards, recognition as well as return on
hardwork.Transactional leaders recognise the actions of their subordinates in order to achieve
outcomes and develop agreements with them, which makes clear what they want receive if they
do something right and what will happen if they do something wrong (Waldman, Ramirez,
House & Puranam, 2001). Basing on the propositions of these two theorists, it is reasonable to
suggest that leadership practices may be related to productivity of academic staff even in
polytechnics.
RELATED LITERATURE
Transformational leadership refers to the practice where one or more persons engage with others
in such a way that leaders and followers raise one another to higher levels of motivation and
morality (Chandna and Krishnan, 2009). Therefore, transformational leadership practices are
mechanisms employed by leaders to get extraordinary things done. Transformational leadership
practices include modelling, inspiring a shared vision, challenging the process, enabling others to
act and encouraging the heart (Abu-Tineh, Khasawneh and Al-Omari, 2008). The leaders
generate enthusiasm and excitement for the common vision from others (Kouzes & Posner,
2002).Modelling involves the leaders exhibiting the behaviour they expect from followers by
setting example (Sharma & Jain, 2013).According to Kouzes and Posner (2003), challenging the
process means that leaders venture out into the unknown. Leaders guide followers through
innovation, change, or the unknown. People are encouraged to follow because leaders create a a
climate that is conducive for experimentation. A follower feel supported and willing to join in
the risk (Posner, 2015).Enabling others to act refers to fostering collaboration and strengthening
others (Kouzes and Posner, 2010). People are encourage and motivated to achieve the goals set
by the organisation (Abu-Tineh et al., 2008). Encouraging the heart involves encouraging and

caring about employees while focusing on the team’s results. Leaders relate to employees with
kindness, respect and fairness which increases productivity (Al-Baradie, 2014).
Obiwuru, Okwu, Akpa and Nwankwere (2011) investigated the effects of leadership style on
organisational performance in small-scale enterprises in Nigeria. The findings of the study
revealed that transformational leadership style had a positive but insignificant effect on
performance. Pradeep and Prabhu (2011) studied the relationship between effective leadership
and employee performance in public and private sector organisations in India. Their findings
revealed that transformational leadership had a significant positive relationship with the
employee performance/ outcomes. Singh (2015) examined the relationship between the
leadership styles and employee productivity in private and foreign banks of US origin in India.
The findings indicated that transformational leadership played a significant role in predicting
employee productivity in foreign banks. Paracha, Qamar, Mirza, Hassan and Waqas (2012)
studied the impact of leadership style (transformational and transactional leadership) on
employee performance in private schools in Pakistan. Their results indicated that
transformational leadership has a significant positive correlation with employee performance.
Thamrin (2012) analysed the influence of transformational leadership and employee performance
in shipping company in Jakarta, Indonesia. The results showed that transformational leadership
had a positive significant influence on employees’ performance. Wang, Oh, Court right and
Colbert (2011) in a meta-analysis on transformational leadership and performance across criteria
and levels found out that transformational leadership has a positive significant relationship with
individual and team level organisational performance. However, as the above studies suggest,
many earlier studies have been carried out in the context of Asia such India (Pradeep and Prabhu,
2011; Singh, 2015), Pakistan (Paracha et al., 2012) and Thamrin (2012) Indonesia. Besides, all
the other studies found that transformational leadership had a positive significant effect, in which
the Nigerian context. Obiwuru et al. (2011) found that it had an insignificant effect. These gaps
thus made it necessary for further research in the Nigerian context to investigate the hypothesis
that: Transformational leadership influences academic staff productivity.
Transactional leadership focuses on the role of supervision, organisation and group performance.
The transactional leader promotes compliance of followers through both rewards and
punishments.Transactional leaders use reward and punishments to gain compliance from their
followers (Odumeru and Ogbonna, 2013). Transactional leaders are focused on short- term goals,
standards, procedures, rules and control (Nikezić, Purić & Purić, 2012). Transactional leaders
recognise what the followers want and help them to achieve goals through an exchange. The
leader approaches followers with the promise of reward. Transactional leadership practices are
namely; contingent reward and management by active or passive exception (Xirasagar, 2008).
Contingent rewards are rewards that are connected to the performance of the employee. If
employee puts efforts it is recognised by the rewards (Chaudhry and Javed, 2012). Contingent
rewards (such as praise) are given when the set goals are accomplished on-time, ahead of time,
or to keep subordinates working at a good pace at different times throughout completion
(Odumeru and Ogbonna, 2013). Active management-by-exception means that the leader
continually looks at each subordinate's performance and makes changes to the subordinate's
work to make corrections throughout the process (Gujral, 2012). Whenever there is deviation
from the rules and regulations, management by expectation happens and the actions for
corrections taken (Chaudhry and Javed, 2012).Passive exception refers to the situation where

leaders wait for issues to come up before fixing the problems (Odumeru & Ogbonna, 2013). A
passive engagement leader gets involved in the process only when standards are not met, or
performance is not achieved (Densten, 2006). Passive leaders will not provide the needed
normative presence to convey expectations regarding employees’ behaviour and their treatment
of one another (Harold & Holtz, 2015).Ejere and Abasilim (2013) investigated the impact of
transactional and transformational leadership styles on organisational performance in the Nigeria
using employees of Akwa Ibom Water Company Limited, Uyo. Their results showed that
transactional leadership style had positive impact on organisational performance. Obiwuru et al.
(2011) investigated the effects of leadership style on organisational performance and found out
that transactional leadership style had a significant positive effect on organization performance.
Ojokuku, Odetayo and Sajuyigbe (2012) examined the impact of leadership style on
organisational performance in selected Banks in Ibadan Nigeria. Regression results showed that
transactional leadership as a negative and insignificant predictor of organisational performance.
Pradeep and Prabhu (2011) in their study conducted in India revealed that transactional
leadership had a significant positive relationship with employee performance. On the other hand,
Paracha et al. (2012) in their study has established a significant positive correlation between
transactional leadership and employee performance. Singh (2015) found out that transactional
leadership played a significant role in predicting employee productivity in private banks in
India.However, the findings above present an empirical gap. Whereas all the other studies found
that transactional had a positive significant effect, Ojokuku et al. (2012) in a study in Nigeria
found that it had a negative insignificant effect. This controversy made it imperative for this
study in the context of polytechnic in Nigeria to test the hypothesis that: HI Transactional
leadership is a correlate of academic staff productivity.
METHODOLOGY
Instrument
Using the quantitative approach, survey and descriptive design, were used and data were
collected using a self-administered questionnaire (SAQ). The questionnaire comprised three
sections. Section A was on the background characteristics of the respondents with questions on
the polytechnic, ownership of the polytechnic, position of the respondent in the polytechnic and
terms of employment. Section B covered the items on leadership practices (independent variable).
Section C covered the dependent variable (DV) which is academic staff productivity with five
aspects namely teaching, supervision, research and publications, innovation and community
services. The questions in section A were nominal questions with appropriate responses required.
The questions in sections B and C were ordinal questions scaled using the four-point Likert scale
from a minimum of 1 strongly disagree (SD), 2 disagree (D), 3 agree (A) and 4 strongly agree
(SD).
Sample Size
Using the self-administered questionnaire (SAQ), data were collected from 285 respondents from
sixpolytechnics that were three federal and state owned. The sample size was attained using two-
stage sampling whereby in the first stagethe polytechnics were clustered according to states. In

stage two, the polytechnics were stratified according to ownership, that is federal or state owned.
The polytechnics studied were as follows; State Polytechnic and Hussaini Adamu Federal
Polytechnic in Jigawa State; Nuhu Bamalli State Polytechnic and Kaduna Federal Polytechnic in
Kaduna; Mohammed Abdullahi Wase Federal Polytechnic and Kano State Polytechnic in Kano
State; Hassan Usman Katsina State Polytechnic and federal Polytechnic Katsina in Katsina State;
Kebbi State Polytechnic and Federal Polytechnic, Birnin-Kebbi in Kebbi; Sokoto State
Polytechnic and Kaura Namoda Federal Polytechnic in Sokoto; Abdul Gusau Polytechnic and
Federal Polytechnic Kaura Namoda in Zamfara State.
Data Management
The data collected were processed by coding all data questionnaires, entering them into the
computer using the Statistical Package for Social Sciences (SPSS), summarising them using
frequency tables and editing them to remove errors. To establish validity, Factor Analysis and
only items that loaded 0.50 once on the component/ factor were adopted (Marsh, Morin, Parker
& Kaur, 2014). Reliability was determined by calculating Cronbach alpha using SPSS. All the
items attained reliability above the benchmark 0.7 (Amin, 2005) as follows; teaching (α = 0.873),
supervision (α = 0.763), publication (α = 0.811), innovation (α = 0.809), community service (α =
0.930), transformational leadership (α = 0.893) and transactional leadership (α = 0.783). The data
analysis involved descriptive and regression analyses. Descriptive analysis involved percentages
from the frequency tables and the mean. Regression analysis involved building a predictive
model by regressing the numerical index of the dependent variable that is academic staff
productivity on the numerical indexes of the independent variables (IVs), namely
transformational and transactional leadership practices. The Statistical Package for Social
Sciences (SPSS) was used to carry out data analysis.

Employee Productivity
The dependent variable was divided into aspects namely; teaching, supervision, publications,
innovation and community services.The items were scaled using the four-point Likert scale
ranging from a minimum of 1 for the worst case scenario (strongly disagree) to a maximum of 4,
which is the best case scenario (Strongly agree). Table 2(a) illustrates that for teaching, all the
nine items had means of about 3, and an overall mean of about 3, which on the scale used
corresponded to “agree” and hence a good overall self-rating of the respondents on teaching.
Table 2 (b) also illustrates that for supervision, all the four items had means of about 3, and an
overall mean of about 3, which on the scale used corresponded to “agree” and hence a good
overall self-rating of the respondents on supervision. Table 2 (c) indicates that for publications,
all the seven items had means of almost 3, and an overall mean of about 2.90, which on the scale
used corresponded to “agree” and hence a good overall self-rating of the respondents on
publications. Table 2 (d) indicates that for innovation, all the four items had means of about 2,
and an overall mean of about 2, which on the scale used corresponded to “disagree” and hence a
poor overall self-rating of the respondents on innovation. Table 2 (e) reveals that for community
service, all the eight items had means of about 3, and an overall mean of about 3, which on the
scale used corresponded to “agree” and hence a good overall self-rating of the respondents on
community service.

Statistical Model for Prediction Employee Productivity Using Leadership Practices
To establish whether the leadership practices predicted the employee productivity of the
academic staff in polytechnics, the dependent variable namely, employee productivity was
regressed against the independent variables leadership practices the results on the same results
are in Table 4.

The results in Table 4.32 show that the two leadership practices explained 3.8% of the variation
in academic staff productivity (adjusted R2 = 0.038). This means that 96.2% of the joint variation
was accounted for by other factors not considered under this paper. The regression model was
significant (F = 5.512, p = 0.005 < 0.05). Only the transformational leadership practice (β =
0.148, p = 0.016 < 0.05) was a positive significant predictor academic staff productivity while
transactional leadership practice (-0.008, p= 0.906 > 0.05) was not.
The study revealed that the first hypothesis (HI) that transformational leadership influences
academic staff productivity was supported. This finding was consistent with the finding by
Pradeep and Prabhu (2011) that transformational leadership had a significant positive
relationship with the employee performance/ outcomes. Similarly, Paracha et al. (2012) indicated that transformational leadership significantly positivelly correlated with employee performance.
Likewise,Singh (2015) found that transformational leadership had significant role in predicting
employee productivity.Equally, Thamrin (2012) showed that transformational leadership had a
positive significant influence on employees’ performance. Further still, Wang et al (2011)
revealed that transformational leadership positively significantly related with individual and team
level organisational performance However, the finding was inconsistent with the finding by
Obiwuru et al. (2011) that transformational leadership style had a positive but insignificant effect
on performance. However, with the finding consistent with most of the earlier studies, the results
suggest that transformational leadership has a positive significant relationship with academic
staff productivity. On the other hand, the findings revealed that transactional leadership practice
had an insignificant influence on employee productivity. This finding supports the finding
byOjokuku et al. (2012) that transactional leadership was an insignificant predictor of
organisational performance. However, this was contrary with the findings of other scholars. For
instance,Ejere and Abasilim (2013) found that transactional leadership style had positive impact
on organisational performance. Similarly, Obiwuru et al. (2011) revealed that transactional
leadership style had a significant positive effect on performance. Pradeep and Prabhu (2011) in
their study in India revealed that transactional leadership had a significant positive relationship
with employee performance. Likewise, Paracha et al. (2012) established a significant positive
correlation between transactional leadership and employee performance. Still, Singh (2015)
found out that transactional leadership played a significant role in predicting employee
productivity in private banks in India. These results suggest that the influence of transactional
leadership was depended on the context of different organisations. The study findings above
reveal that that the most appropriate leadership practice was the transformational leadership

practice. This study therefore recommends that managers of organisations such as polytechnics
should emphasise the transformational leadership practice in providing leadership to their staff.
CONCLUSIONS
Extant scholarly literature reveals that employee productivity has a significant positive influence
on performance of organisations. Productive employee accomplish organisational goals and
objectives, effectively perform of tasks,use resources efficiently, have quality of output,
workmanship, adherence to standards and lead to customer satisfaction. This paper reported on a
survey on employee productivity in polytechnic in North Western Nigeria with the purpose
linking employee productivity with two leadership practices, namely transformational and
transactional. In this attempt, the study closed gaps such as the study being carried out in the
context of polytechnics and in the context of Africa that had been largely ignored by earlier
studies. The study also emphasised that transformational leadership was a significant predictor
employee productivity which had disputed by scholars such as Ojokuku et al. (2012) that
transactional leadership was an insignificant predictor of organisational performance.
RECOMMENDATIONS
The findings of this study have practical significance to managers of academic institutions in
Nigeria such as polytechnics. In particular, the finding that transformational leadership is a
significant a positive predictor suggests that it is an important factor of employee productivity.
Therefore, this study recommends that managers of organisations such as polytechnics should
emphasise the transformational leadership practice in providing leadership to their staff.
Conversely, the finding that transactional leadership did significantly predict employee
productivity leads to the assumption that it is not a very important factor in the effort to promote
productivity of academic staff.
