The primary purpose of the current study was to assess the role of organizational justice in understanding prison staff job stress. Specifically, the authors surveyed 322 correctional employees across two prisons located in Guangzhou, China to explore the effects of distributive, procedural, informational, and interpersonal justice on work stress. Results from ordinary least squares analysis revealed significant contributions from three dimensions of organizational justice in explaining stress from work among prison workers. Prison personnel who had higher perceptions of interpersonal, distributive, and procedural justice in the organization were less likely to report being stressed. In addition, men were more likely to report higher levels of work tension than women.
