Worker participation in decision-making is crucial for fostering positive employer-worker relationships. Traditionally, decision-making in organizations has been the exclusive domain of top management, often excluding lower-level employees who are essential for implementing these decisions (Ozoegwu & Akpan, 2021). This exclusion results in a lack of critical input from workers, leading to resistance, dissatisfaction, and poor implementation of decisions. In contemporary Nigerian banks, the need for worker involvement in decision-making has become increasingly important to maintain competitiveness and adaptability (Obada et al., 2024). This study evaluates worker participation in decision-making at First Bank Nigeria Limited, emphasizing its impact on organizational performance, worker satisfaction, and productivity. Participation is defined as the process through which employees influence their work conditions and share responsibility for organizational goals (Edomah et al., 2021). It involves workers in the initiation, formulation, and implementation of decisions, creating a sense of belonging and improving industrial relations (Ibrahim et al., 2021). The benefits of worker participation include enhanced job satisfaction, commitment, and organizational performance (Ascani et al., 2021; Bakre et al., 2022). However, non-involvement can lead to job dissatisfaction, decreased productivity, and negative health effects (Ogunkan, 2022; Adediran et al., 2024). This study explores the causes and consequences of low worker participation in decision-making and suggests measures to improve involvement. Using First Bank Nigeria Limited as a case study, it aims to understand the impact of worker participation on decision implementation and overall organizational effectiveness. The research addresses the need to enhance worker involvement to achieve better human relations and organizational goals, providing insights and recommendations for managers and future researchers.
