Organizational justice is a construct defining the quality of social interaction at work. Organizational justice can be divided into three categories: procedural justice (fairness of the decision-making procedures), distributive justice (fairness of outcomes) and relational justice (equity and fairness in the interpersonal treatment of employees by their supervisors). Organizational justice is related to employees' health and well-being. Low perceived justice has been shown to be associated with experienced stress reactions and related physiological and behavioral reactions, such as inflammation, sleeping problems, cardiovascular regulation and cognitive impairments, and with a high rate of work absenteeism. This paper is a review of the literature on organizational justice and its impact on workers' health.
