Project – Influence of Ethical Leadership on Employee Trust and Organisational Commitment: A Study of Selected Manufacturing Companies in Ogun State

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Leadership is a central component of organisational effectiveness because leaders influence employees’ attitudes, behaviours, perceptions and willingness to contribute to organisational objectives. In contemporary organisations, leadership effectiveness is increasingly assessed not only by the ability of managers to achieve performance targets but also by the ethical standards demonstrated in the process of achieving those targets. Ethical leadership refers broadly to the demonstration of normatively appropriate conduct through personal actions and interpersonal relationships, together with the promotion of such conduct among followers through communication, reinforcement and decision-making. Brown, Treviño, and Harrison (2005) established ethical leadership as a distinct leadership construct and demonstrated that it is associated with honesty, fairness, trust in leaders, job satisfaction and employee dedication. Their social learning perspective suggests that employees observe the conduct of leaders and may model behaviours they perceive to be acceptable within the organisation. Consequently, leaders who consistently demonstrate integrity, fairness, responsibility and concern for employees can contribute to a workplace climate in which ethical conduct and positive employee relationships are encouraged.

The importance of ethical leadership becomes particularly significant in organisations where employees depend heavily on management decisions concerning remuneration, promotion, workload, discipline, safety, performance evaluation and career opportunities. Employees are more likely to develop confidence in leadership when managers demonstrate consistency between what they say and what they do. Brown and Treviño (2006) noted that ethical leadership involves both the moral-person dimension, which reflects characteristics such as honesty and integrity, and the moral-manager dimension, which involves actively communicating ethical standards and reinforcing appropriate conduct. This implies that ethical leadership extends beyond a leader’s personal character to include deliberate managerial practices that communicate fairness and acceptable standards throughout the organisation. In manufacturing companies, where employees often operate within formal hierarchies, production targets and clearly defined procedures, the ethical conduct of supervisors and managers can therefore have important implications for employees’ perceptions of fairness, respect and organisational reliability.

Employee trust is another important organisational outcome that may be influenced by leadership behaviour. Trust in an organisational context involves an employee’s willingness to accept vulnerability based on positive expectations concerning the intentions, competence, integrity and behaviour of another party. Mayer, Davis, and Schoorman (1995) developed an influential integrative model of organisational trust which identifies ability, benevolence and integrity as important antecedents of trustworthiness. From this perspective, employees are more likely to trust leaders when they believe that leaders are competent, genuinely concerned about their welfare and committed to principles that guide their behaviour consistently. Dirks and Ferrin (2002), in a meta-analysis of research on trust in leadership, found that trust in leaders is associated with important employee attitudes and organisational outcomes and that direct leaders, such as supervisors, are particularly important referents of employee trust. Thus, leadership practices that demonstrate honesty, fairness, transparency and consistency can be particularly relevant to the development of trust within manufacturing organisations.

Organisational commitment is also a critical employee attitude because it reflects the psychological relationship between employees and the organisations in which they work. Meyer and Allen (1991) conceptualised organisational commitment as comprising three components: affective commitment, continuance commitment and normative commitment. Affective commitment refers to employees’ emotional attachment to and identification with the organisation; continuance commitment concerns the perceived costs associated with leaving; while normative commitment reflects a sense of obligation to remain with the organisation. Ethical leadership may influence these dimensions by creating an organisational environment in which employees perceive that management respects their contributions, treats them fairly and acts consistently with accepted standards. Where employees perceive leaders as trustworthy and morally responsible, they may develop stronger emotional attachment and identification with their organisations rather than viewing employment merely as an economic exchange.

The relationship between ethical leadership, trust and commitment has received increasing scholarly attention because employees’ responses to leadership may extend beyond immediate job satisfaction to deeper psychological attachment to the organisation. Brown et al. (2005) found that ethical leadership was related to trust in leaders, job satisfaction and employee dedication, suggesting that ethical conduct can shape important employee attitudes. Similarly, Dirks and Ferrin (2002) demonstrated through meta-analytic evidence that trust in leadership has meaningful relationships with employee attitudes and behaviours. More recent research has continued to examine the connection among ethical leadership, trust and organisational commitment. A 2026 study reported that ethical leadership positively shaped ethical culture and organisational commitment, while employee trust strengthened the relationships between these organisational factors. Although that study was situated in the public-sector context, its findings reinforce the argument that trust is an important mechanism through which leadership practices can influence employee commitment.

The Nigerian organisational environment provides an important context for examining ethical leadership because organisations operate within complex economic, social and institutional conditions that can affect employee-management relationships. In Nigeria, issues relating to managerial fairness, transparency, employee welfare, accountability and workplace relationships remain important considerations for organisations seeking sustainable performance. Research involving Nigerian employees has also demonstrated the relevance of leadership behaviour to organisational commitment. For example, a Nigerian study by Walumbwa et al. (2017) found positive relationships between authentic leadership behaviours and employee organisational commitment, providing evidence that leadership characteristics involving transparency and authenticity can influence employees’ attachment to their organisations. More recently, Abasilim and David (2026) examined ethical leadership strategies and employee engagement in Ado-Odo/Ota Local Government Area of Ogun State and highlighted the importance of ethical leadership in strengthening positive employee outcomes within the Nigerian context. These findings are relevant to the present study because Ogun State contains a substantial concentration of industrial and manufacturing activities, making leadership and employee-management relationships important areas of organisational research.

Ogun State is widely recognised as one of Nigeria’s important industrial environments, with manufacturing activities spread across areas such as Agbara, Ota, Sagamu, Abeokuta and other industrial clusters. Manufacturing organisations depend heavily on human resources for production, quality control, maintenance, logistics, administration and other operational activities. In such environments, leadership practices may influence whether employees perceive management as trustworthy and whether they develop a strong commitment to their organisations. Ethical leadership may be particularly relevant because manufacturing employees often encounter decisions concerning production pressure, workplace safety, disciplinary procedures, overtime, performance appraisal and resource allocation. Where employees perceive leadership decisions as fair and transparent, trust and commitment may be strengthened; conversely, perceived favouritism, inconsistency, dishonesty or disregard for employee welfare may weaken these attitudes. Existing scholarship establishes strong theoretical links between ethical leadership, trust and commitment, while Nigerian evidence demonstrates that leadership behaviours are relevant to employee attitudes. However, there remains a need for context-specific empirical evidence concerning the combined influence of ethical leadership on employee trust and organisational commitment among manufacturing companies in Ogun State. This provides the rationale for the present study.

1.2 Statement of the Problem

Manufacturing companies depend on committed employees who are willing to contribute their skills, knowledge and effort towards the achievement of organisational objectives. However, achieving employee commitment may become difficult when workers perceive that organisational leaders do not consistently demonstrate fairness, integrity, transparency and concern for employee welfare. Ethical leadership is expected to provide a basis for establishing acceptable standards of managerial behaviour, yet the existence of formal organisational policies does not necessarily guarantee that managers consistently practise those standards. Brown et al. (2005) observed that ethical leadership is associated with trust, job satisfaction and employee dedication, indicating that leaders’ ethical conduct can have important consequences for employee attitudes. The problem therefore arises when a gap exists between organisational expectations concerning ethical leadership and employees’ actual experiences of managerial behaviour.

A related problem concerns the development and maintenance of employee trust. Trust is essential because employees frequently operate under conditions in which they cannot completely monitor or control managerial decisions. They must therefore rely on expectations that leaders will act competently, fairly and with integrity. Mayer et al. (1995) argued that trust involves a willingness to accept vulnerability based on expectations concerning the trustworthiness of another party, while Dirks and Ferrin (2002) established through meta-analytic evidence that trust in leadership is related to important organisational outcomes. In manufacturing companies, low levels of trust may manifest through reluctance to communicate openly with supervisors, reduced willingness to report workplace problems, suspicion concerning management decisions and weaker cooperation between employees and management. If such conditions persist, the relationship between management and employees may become increasingly transactional rather than based on mutual confidence.

The problem is further reflected in concerns about organisational commitment. Manufacturing organisations may invest substantial resources in recruiting, training and developing employees, yet employees who lack emotional attachment or a sense of obligation to the organisation may demonstrate weaker identification with organisational objectives and may be more inclined to consider alternative employment opportunities. Meyer and Allen (1991) explained that organisational commitment includes affective, continuance and normative dimensions, each reflecting different reasons why employees remain with an organisation. While employees may remain because they need their jobs or feel obligated to stay, such forms of attachment may not necessarily reflect strong emotional identification with the organisation. Ethical leadership may therefore be important in creating the conditions under which employees develop a stronger and more positive psychological relationship with their organisations.

Despite the theoretical and empirical evidence linking ethical leadership with trust and positive employee attitudes, there remains a need for more context-specific investigation of these relationships within Nigerian manufacturing organisations, particularly in Ogun State. Existing studies have examined ethical leadership and related employee outcomes in different sectors and locations, including studies of trust, commitment and employee engagement, but findings from one organisational or geographical context cannot automatically be generalised to manufacturing companies in Ogun State. The 2026 study by Abasilim and David, for example, examined ethical leadership and employee engagement in Ado-Odo/Ota, Ogun State, while Brown et al. (2005) and Dirks and Ferrin (2002) provide broader international evidence concerning ethical leadership and trust. There is therefore a research gap concerning the extent to which ethical leadership influences both employee trust and organisational commitment among selected manufacturing companies in Ogun State. The present study seeks to address this gap by empirically examining the relationship between ethical leadership, employee trust and organisational commitment in the selected manufacturing context.

1.3 Purpose of the Study

The main purpose of this study is to examine the influence of ethical leadership on employee trust and organisational commitment among selected manufacturing companies in Ogun State.

Specifically, the study seeks to:

1. examine the level of ethical leadership practices among managers of selected manufacturing companies in Ogun State;
2. determine the level of employee trust in the leadership of selected manufacturing companies in Ogun State;
3. assess the level of organisational commitment among employees of selected manufacturing companies in Ogun State;
4. examine the influence of ethical leadership on employee trust among employees of selected manufacturing companies in Ogun State

1.4 Research Questions

The following research questions will guide the study:

1. What is the level of ethical leadership practices among managers of selected manufacturing companies in Ogun State?
2. What is the level of employee trust in the leadership of selected manufacturing companies in Ogun State?
3. What is the level of organisational commitment among employees of selected manufacturing companies in Ogun State?
4. To what extent does ethical leadership influence employee trust among employees of selected manufacturing companies in Ogun State?

1.5 Research Hypothesis

The following null hypothesis will be tested at the 0.05 level of significance:

H₀: Ethical leadership has no significant influence on employee trust and organisational commitment among employees of selected manufacturing companies in Ogun State.

1.6 Significance of the Study

The study will be significant to management of manufacturing companies because it will provide empirical information on how ethical leadership practices may affect employees’ trust in management and their commitment to the organisation. The findings may assist managers in identifying leadership behaviours that encourage fairness, transparency, accountability and integrity.

The study will also be useful to employees because it may draw attention to the importance of ethical treatment, transparent communication, fairness and managerial integrity in creating a positive work environment. A better understanding of these issues may encourage constructive relationships between employees and organisational leaders.

The findings will be relevant to human resource managers and practitioners because they may provide evidence for designing leadership-development programmes, ethical codes, managerial training and employee-relations policies aimed at strengthening trust and organisational commitment.

The study may also benefit policy makers and regulatory institutions concerned with labour and industrial relations in Nigeria. The findings may provide useful information for understanding how organisational leadership practices can contribute to healthier employee-management relationships within the manufacturing sector.

Finally, the study will contribute to academic knowledge by providing empirical evidence on the relationship between ethical leadership, employee trust and organisational commitment within the Nigerian manufacturing context. It may also serve as a reference for future researchers interested in leadership, organisational behaviour, human resource management and employee relations.

1.7 Scope of the Study
