SummaryThe relationship between organizational justice perceptions, job satisfaction, and Organizational citizenship behaviour (OCB) from the responses of 267 employees in the manufacturing sector showed that interpersonal justice positively influenced all dimensions of OCB. Among the justice factors, informational justice had a greater influence on job satisfaction than distributive justice, procedural justice, or interpersonal justice. The effect of job satisfaction on OCB was most significant on civic virtue, followed by courtesy, altruism, conscientiousness, and sportsmanship. The mediation analysis showed that job satisfaction fully mediated the relationship between organizational justice and OCB. Therefore, job satisfaction is a stronger predictor of citizenship behaviours than justice perceptions.
