The aim of this study was to explore the relationship between organizational justice and organizational citizenship behaviour. The research was conducted on larger convenience sample of employees hierarchically structured organizations that represent a variety of different industries on the area of the Republic of Croatia. This study aimed to examine the effects of dimensions of organizational justice (distributive, procedural, interactional and overall) on the different dimensions of organizational citizenship behaviour (interpersonal citizenship performance, organizational citizenship performance, job/task citizenship performance and overall) and also to determine whether there are differences in the perceptions of organizational justice and organizational citizenship behaviour regarding tenure, educational level and participants hierarchical position in the organization. The results showed positive correlations between all dimensions of organizational justice and dimensions of organizational citizenship behaviour. Results of the regression analysis suggest interactional justice as the strongest predictor of all dimensions and overall organizational citizenship behaviour. Results of multiple one-way analysis of variance suggest a significant difference in the perceptions of procedural and interactional justice regarding participants job tenure, and in the perceptions of distributive, procedural, interactional and overall justice regarding participants hierarchical position in the organization. Also, results of multiple one-way analysis of variance revealed significant differences in interpersonal citizenship performance, organizational citizenship performance, job/task citizenship performance and overall citizenship behaviour regarding participants educational level, and in interpersonal citizenship performance, organizational citizenship performance and overall citizenship behaviour regarding participants hierarchical position.
