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.
