An investigation of relation between organizational justice and professional commitment of staff: A case study of public organization in Kermanshah

This paper presents an empirical study to investigate the relationship between organizational justice and professional commitment in Kermanshah official organizations. The study uses 20 questions to measure professional commitment from a questionnaire originally developed by Spell et al. (2007) [Spell, C. S., & Arnold, T. J. (2007). A multi-level analysis of organizational justice climate, structure, and employee mental health. Journal of Management, 33(5), 724-751.]. In addition, the study adopts 12 questions from another questionnaire developed by Vallas (1999) [Vallas, S. P. (1999). Rethinking post?Fordism: The meaning of workplace flexibility. Sociological theory, 17(1), 68-101.] to measure organizational justice. Cronbach alpha for organizational justice questionnaire and professional commitment are 0.81 and 0.89, respectively, which are well above the minimum acceptable level. Based on the results of this survey, there is a positive and meaningful relationship between organizational justice and professional commitment. The implementation of the linear regression analysis also reveals that there is a positive and meaningful relationship between inter-organizational justice and professional commitment. The study performs Freedman test to rank three components of organizational justice and the results indicate that interactional justice maintains the highest level of importance while distributive justice comes last in terms of priority.
