EFFECT OF LEADERSHIP STYLE ON EMPLOYEE JOB SATISFACTION, A STUDY OF NIGERIAN BREWERIES PLC

ABSTRACT

Leadership remains one of the most decisive variables shaping how employees experience their work, and in a manufacturing environment such as brewing, where production targets, shift rotations and strict quality and safety compliance intersect with a large and diverse workforce, the manner in which supervisors and managers relate to subordinates carries direct consequences for morale, retention and productivity. This study examines the effect of leadership style on employee job satisfaction, using Nigerian Breweries Plc as a case study. Although a growing body of Nigerian literature links leadership approaches to workplace outcomes, findings on which style, transformational, transactional or laissez-faire, best predicts satisfaction within the brewing sub-sector remain inconclusive, with some studies reporting weak, negligible or even counter-intuitive correlations between transformational leadership and satisfaction outcomes, while other dimensions show stronger associations. This inconsistency, combined with reports of morale challenges, workforce restructuring and cost-cutting pressures across the Nigerian brewing industry since 2020, motivates the present inquiry. The study is guided by three specific objectives: to determine the relationship between transformational leadership and employee job satisfaction, to examine the influence of transactional leadership on employee job satisfaction, and to assess the effect of laissez-faire leadership on employee job satisfaction among staff of Nigerian Breweries Plc. A quantitative survey design anchored on the Full Range Leadership Theory and Herzberg's Two-Factor Theory is proposed, with data to be drawn from management and non-management staff across selected operating locations. The findings will provide evidence-based guidance for leadership development and employee-engagement interventions within Nigerian Breweries Plc and comparable manufacturing organisations operating in Nigeria's fast-moving consumer goods sector.

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Leadership is widely regarded as the single most influential factor in determining the direction, cohesion and performance of any organisation. It is the process through which an individual influences a group of people to achieve a common goal, and the particular pattern of behaviour a leader consistently exhibits while directing subordinates constitutes what scholars describe as leadership style. Since Burns (1978) first distinguished transactional from transformational leadership, and Bass (1985) subsequently extended the framework into what is now known as the Full Range Leadership Model, comprising transformational, transactional and laissez-faire dimensions, organisational behaviour researchers have consistently examined how these styles shape employee attitudes, particularly job satisfaction, which refers to the extent to which employees feel positively or negatively about the various facets of their work.

In the manufacturing and fast-moving consumer goods sector, where Nigerian Breweries Plc has operated for close to eight decades as the pioneer and one of the largest brewing companies in Nigeria, leadership takes on added significance because of the scale of operations, the shift-based nature of production work, and the constant pressure to meet output targets while maintaining product quality and workplace safety. Nigerian Breweries Plc, a subsidiary of Heineken N.V., operates multiple breweries and a large distribution network across the country, and its ability to sustain productivity depends considerably on how satisfied its workforce is with supervisory and managerial conduct. Recent sector-specific research underscores this link: a 2020 study published in the Ilorin Journal of Human Resource Management investigated leadership styles and job satisfaction among employees of the Nigerian breweries industry using the Multifactor Leadership Questionnaire and a validated job satisfaction scale, and found that transformational, transactional and laissez-faire leadership styles were all statistically connected to employees' level of job satisfaction, although the strength of the relationships varied considerably, with transformational leadership showing an unexpectedly weak association while laissez-faire leadership showed a comparatively stronger one (Abidakun & Ganiyu, 2020). A separate 2024 study on Nigerian Breweries Plc's South-East operations similarly found that transformational leadership practices accounted for a very large share of the variation in employee performance observed among staff, reinforcing the view that leadership transitions and styles produce measurable effects on how employees experience and respond to their work environment.

Beyond the Nigerian brewing sector, the broader literature on transformational leadership continues to affirm its capacity to shape employee attitudes positively. Chen et al. (2021) observed that transformational leadership can influence how employees interpret organisational change, while studies conducted within Nigerian industrial settings, including the natural gas and small and medium enterprise sub-sectors, have found that dimensions of transformational leadership such as inspirational motivation and individualised consideration are associated with higher levels of employee satisfaction and engagement, even though the mediating mechanisms through which these effects occur remain only partly understood (Kavitha & Amala, 2022; Darmadi et al., 2023; Baldwin et al., 2022). At the same time, other researchers caution that the practical application of transformational leadership within Nigerian organisations, including small and medium-sized enterprises, is frequently inconsistent because of limited leadership training and resource constraints, which can blunt its expected benefits (Manzoor et al., 2019; Meiryani et al., 2022).

Since 2020, the Nigerian brewing industry has also had to contend with a difficult macroeconomic environment, including the residual effects of the COVID-19 pandemic on consumer demand, repeated increases in excise duty on alcoholic beverages, foreign exchange scarcity affecting the importation of raw materials, and rising energy and logistics costs. These pressures have, in several instances, translated into cost-containment measures, restructuring and, in some cases, plant closures across the industry, developments that place additional strain on employee morale and make the role of leadership in sustaining job satisfaction even more critical. It is against this backdrop of a well-documented but still contested relationship between leadership style and job satisfaction, and a business environment that has grown more turbulent in recent years, that this study sets out to examine how transformational, transactional and laissez-faire leadership styles affect employee job satisfaction at Nigerian Breweries Plc.

1.2 Statement of the Problem

Despite the considerable volume of research linking leadership style to employee job satisfaction, the direction and strength of this relationship within Nigeria's brewing industry remains unsettled. Existing empirical evidence is notably mixed: while some studies report that transactional and laissez-faire leadership styles are more strongly associated with job satisfaction than transformational leadership within the Nigerian breweries context, a finding that runs counter to the dominant theoretical expectation that transformational leadership should be the most positively associated style, other studies on Nigerian manufacturing and industrial firms report the opposite pattern, with transformational leadership emerging as the strongest predictor of satisfaction (Abidakun & Ganiyu, 2020; Kavitha & Amala, 2022). This lack of consensus makes it difficult for managers within Nigerian Breweries Plc and similar organisations to know with confidence which leadership approach to prioritise in staff development and supervisory training programmes.

Compounding this uncertainty is the observation that, despite the company's long-standing reputation for structured management practices, informal reports and industry commentary point to recurring concerns among brewery workers around perceived favouritism, limited participation in decision-making, inconsistent recognition of performance, and communication gaps between management and shop-floor staff, all of which are symptomatic of leadership style mismatches. If these concerns are not systematically investigated and addressed, they carry the risk of translating into higher labour turnover, reduced productivity, poor product quality outcomes and reputational damage for the organisation, particularly at a time when the brewing industry is already contending with excise duty increases, currency depreciation and shrinking consumer purchasing power that leave little room for productivity losses arising from avoidable people-management failures. It is this combination of theoretical inconsistency in the literature and a practical, largely unquantified problem within the case organisation that this study seeks to address by empirically examining the effect of leadership style on employee job satisfaction at Nigerian Breweries Plc.

1.3 Objectives of the Study

The main objective of this study is to examine the effect of leadership style on employee job satisfaction at Nigerian Breweries Plc. The specific objectives are to:

i. determine the effect of transformational leadership style on employee job satisfaction at Nigerian Breweries Plc;

ii. examine the effect of transactional leadership style on employee job satisfaction at Nigerian Breweries Plc;

iii. assess the effect of laissez-faire leadership style on employee job satisfaction at Nigerian Breweries Plc; and

iv. identify which of the three leadership styles has the strongest influence on employee job satisfaction at Nigerian Breweries Plc.

1.4 Research Questions

The study seeks to answer the following research questions:

i. What is the effect of transformational leadership style on employee job satisfaction at Nigerian Breweries Plc?

ii. What is the effect of transactional leadership style on employee job satisfaction at Nigerian Breweries Plc?

iii. What is the effect of laissez-faire leadership style on employee job satisfaction at Nigerian Breweries Plc?

iv. Which of the three leadership styles has the strongest influence on employee job satisfaction at Nigerian Breweries Plc?

1.5 Research Hypotheses

The following hypotheses, stated in the null form, are formulated to guide the study:

Ho1: Transformational leadership style has no significant effect on employee job satisfaction at Nigerian Breweries Plc.

Ho2: Transactional leadership style has no significant effect on employee job satisfaction at Nigerian Breweries Plc.

Ho3: Laissez-faire leadership style has no significant effect on employee job satisfaction at Nigerian Breweries Plc.

1.6 Significance of the Study

This study is significant to several categories of stakeholders. To the management of Nigerian Breweries Plc, the findings will provide empirical evidence on which leadership style, or combination of styles, is most effective in enhancing employee job satisfaction, thereby informing supervisory training, succession planning and leadership development programmes. To human resource practitioners and consultants operating within Nigeria's manufacturing and fast-moving consumer goods sector more broadly, the study offers context-specific insight that can guide the design of leadership interventions attuned to the realities of unionised, shift-based industrial workforces.

To policymakers and industry regulators, the study contributes evidence relevant to discussions on workforce welfare within an industry currently navigating excise duty reforms and macroeconomic headwinds, highlighting how internal leadership practices, and not only fiscal policy, shape organisational resilience. To the academic community, the study extends the existing but still contested body of Nigerian literature on leadership style and job satisfaction within the brewing sub-sector, offering a more current empirical basis against which future researchers can compare findings, particularly given that much of the existing sector-specific evidence predates recent industry disruptions. Finally, to employees of Nigerian Breweries Plc and similar organisations, the study's outcomes may indirectly support workplace conditions that better reflect their expectations of fair, motivating and participatory leadership.

1.7 Scope of the Study

This study is limited in content scope to the examination of three leadership styles, transformational, transactional and laissez-faire, as conceptualised within Bass and Avolio's Full Range Leadership Model, and their effect on employee job satisfaction as conceptualised within Herzberg's Two-Factor Theory. The study does not extend to other organisational outcomes such as financial performance, employee turnover intention or organisational commitment, although these may be referenced contextually where relevant. Geographically, the study is restricted to selected operating locations of Nigerian Breweries Plc, and the population of interest comprises management and non-management staff directly engaged in production, quality assurance, sales and administrative functions. The study is cross-sectional in nature, relying on data collected within a defined period, and its findings are therefore reflective of the prevailing leadership and job satisfaction dynamics at Nigerian Breweries Plc at the time of the survey rather than a longitudinal assessment of change over time.
