Procedural Justice, Employee Perceptions and Change Acceptance in Nigerian State-Owned Enterprises: Evidence from a Large-Scale Structural Equation Model

Organizational change in African state-owned enterprises frequently fails due to rigid governance structures, institutional mistrust, and employee resistance. While reform efforts emphasize technical solutions, the role of fairness perceptions remains underexplored. Understanding how procedural justice shapes employee responses is critical to improving change acceptance and enhancing the effectiveness of public-sector reforms in developing economies. This study develops and empirically tests a structural equation model grounded in procedural justice and social exchange theories. A cross-sectional survey design was employed, collecting data from 1,500 employees of the Nigerian National Petroleum Company across departments, tenure levels, and educational backgrounds. Key constructs include perceived organizational support, fear of change consequences, self-confidence in learning and development, trust in management, and perceived need for change, with procedural justice modeled as a mediating mechanism. Data were analyzed using confirmatory factor analysis to establish reliability and validity, followed by structural equation modeling and bootstrapped mediation analysis to test hypothesized relationships and ensure robustness. The results indicate that perceived need for change is the strongest predictor of employee acceptance of organizational transformation, followed by self-confidence in learning, perceived organizational support, and trust in management. Procedural justice has both a direct and indirect effect, significantly mediating the relationships between most employee perceptions and change acceptance, although its mediating role is not supported in the case of self-confidence. The model explains substantial variance in both procedural justice and reactions to change. Moderation analysis shows that employee tenure strengthens the relationship between perceived need for change and acceptance, while higher education enhances the influence of trust on procedural justice. Robustness checks confirm the stability of findings across alternative specifications and estimation techniques. The findings underscore the importance of embedding procedural justice principles such as transparency, consistency, and participatory decision-making into public-sector reform processes. Policymakers and managers should prioritize fairness-driven engagement, clearly communicate the necessity of change, and address employee concerns through inclusive strategies. Tailoring reform initiatives to workforce characteristics, including tenure and educational level, can improve change acceptance, strengthen institutional trust, and enhance the overall effectiveness of organizational transformation in developing economies.
