Multiple Relationships between Perceived Organizational Justice and Adherence to Psychological Contracts with Organizational Citizenship Behaviors

The main purpose of this research was to study perceived organizational justice and adherence to psychological contracts with organizational citizenship behavior among employees. For this purpose, 280 subjects were selected through stratified random sampling, based on Mitchell and Julie sample size table. The research method was descriptive and correlational. Research instruments consisted of organizational citizenship behavior questionnaire (Lee & Allen, 2002), organizational justice (Niehoff & Moorman, 1993) and psychological contracts (Rousseau, 1995). The data were analyzed by Pearson correlation and simultaneous and stepwise regression. Results indicated that there was a significant relationship between perceived organizational justice in all three dimensions distributive, procedural, interactional and adherence to psychological contracts in two dimensions transactional and relational, with Organizational citizenship behavior toward coworkers and organization (P≤0.01). Also, the results of the regression analysis showed that adherence to transactional psychological contracts, distributive justice and interactional justice has explained 45.7 % of variance in organizational citizenship behavior. Finally, we can conclude that perceived organizational justice and adherence to psychological contracts are important predictive factors of organizational citizenship behaviors.
