Better understanding the perceptions of organizational politics: its impact under different types of work unit structure

Research has uncovered inconsistent results regarding the influence of the perceptions of organizational politics (POP) on employee job performance, suggesting the existence of boundary conditions for such an influence. Drawing from uncertainty management theory, we investigated the interaction effect of POP and work unit structure on job performance, and examined the mediating role of taking charge. We tested the theoretical model with data gathered across three phases over 6 months from 577 individuals and their supervisors in 133 work units. Results showed that when the unit operated an organic structure, POP was significantly negatively related to job performance. In contrast, results demonstrated that when the unit operated a mechanistic structure, POP was significantly positively related to job performance. Furthermore, the results of the mediated moderation analysis revealed that POP was negatively associated with job performance through taking charge in an organic structure, and the indirect effect disappeared in a mechanistic structure.
