Informed by social exchange theory and social identity theory, we developed a conceptual model that examines the mediating role of organizational identification in the relationship between employees’ perceptions of organizational context and their job attitudes. In our model, the antecedents include perceived organizational support (POS), procedural justice, and perceived job insecurity. The outcome variables consist of affective organizational commitment, job satisfaction, and intentions to leave. Our respondents were 591 workers employed in three different firms in China. The results of regression analyses showed that employees’ job attitudes are affected by their perceptions of organizational context and organizational identification. Further, organizational identification was found to mediate the effects of POS on the outcome variables.
