The present research examines how the social identity perspective contributes to a better understanding of the relationships between perceived organizational support, affective commitment, and employees’ performance at work. Using a sample of 253 employees from an engineering company, Study 1 found that organizational identification partially mediates the relationship between perceived organizational support and affective commitment. The results of Study 1 also indicated that the relationship between perceived organizational support and organizational identification is moderated by organizational prestige. In Study 2, using a sample of 179 postal employees, the authors replicated the mediating role of organizational identification in the relationship between perceived organizational support and affective commitment and found that affective commitment mediates the relationship between organizational identification and supervisor’s ratings of extra-role performance.

The present study aims to investigate the contribution of identification to proximal targets in the prediction of affective organizational commitment. Using three sets of cross-sectional data, we found that organizational identification mediates the impact of both occupational and workgroup identification on affective organizational commitment. We also examined the relationship between organizational identification and affective organizational commitment and their effects on two of their common outcomes, that is, job satisfaction and turnover intentions. Our results showed that affective organizational commitment mediates the effect of organizational identification on job satisfaction and turnover intentions.

Although several studies have empirically supported the distinction between organizational identification (OI) and affective commitment (AC), there is still disagreement regarding how they are related. Precisely, little attention has been given to the direction of causality between these two constructs and as to why they have common antecedents and outcomes. This research was designed to fill these gaps. Using a cross-lagged panel design with two measurement times, Study 1 examined the directionality of the relationship between OI and AC, and showed that OI is positively related to temporal change in AC, confirming the antecedence of OI on AC. Using a cross-sectional design, Study 2 investigated the mediating role of OI in the relationship between three work experiences (i.e., perceived organizational support, leader-member exchange, and job autonomy) and AC, and found that OI partially mediates the influence of work experiences on AC. Finally, Study 3 examined longitudinally how OI and AC combine in the prediction of actual turnover, and showed that AC totally mediates the relationship between OI and turnover. Overall, these findings suggest that favorable work experiences operate via OI to increase employees' AC that, in turn, decreases employee turnover.
