Abstract:
The authors hypothesized that supervisors' perceived organizational support (POS) would moderate the relationships between leader-member exchange (LMX), job satisfaction, and job performance. On the basis of social exchange theory, supervisors' exchanges with the organization and subordinates should be interconnected. The authors expected that supervisors with high POS would have more resources to exchange with subordinates. Thus, supervisor POS should enhance the relationships between LMX and job satisfaction and LMX and job performance for subordinates. Hierarchical linear modeling analysis provided support for the hypotheses in a sample of 210 subordinates and 38 supervisors of a grocery store chain. The positive relationship between LMX and job satisfaction was stronger when supervisors had high POS. Moreover, LMX was related to performance only when supervisors had high POS.
