摘要:Background: Research on organizational injustice has mainly focused on the victim’s perspective. This study attempts to contribute to our understanding of third parties’ perspective by empirically testing a model that describes third party reactions to mistreatment of employees. Method: Data were obtained from a sample (N = 334) of Spanish employees from various organizations, nested into 66 work-groups, via a survey regarding their perceptions of organizational mistreatment. Structural equation modeling was used to analyze the data. Results: The proposed model had a limited fit to the data and it was re-specified. Organizational mistreatment, employee performance, and employee organizational commitment explained internal attributions blaming the organization. Moreover, coworkers’ organizational identification showed a positive impact on external attributions of responsibility. Lastly, supportive organizational climate and internal attributions accounted for a large percentage of variance in coworkers’ perceptions of organizational unfairness. Conclusions: The final model explains the perceptions of injustice on the basis of internal attributions of responsibility in the face of organizational mistreatment of employees.
