Abstract

We used two-wave panel data based on a sample of 137 employees from a small Korean manufacturing company to examine first the discriminant validity of, and then the interaction between perceived organizational support (POS) and perceptions of organizational politics (POP). We focused on the relationships between POS, POP, and three employee work-related outcomes, affective organizational commitment, intention to stay, and individually oriented organizational citizenship behaviour (OCBI). Confirmatory factor analysis revealed that POS and POP were distinct constructs. Moreover, time-lagged LISREL estimates showed that POS and POP were differentially related to the three outcomes in a theoretically predictable way. POP did not moderate the relationship between POS and either affective commitment or intention to stay. POS, however, significantly moderated the POP–OCBI relationship. The implications of the results for POS and POP theory and research are discussed.
