Coworker exchange: Relationships between coworkers, leader-member exchange, and work attitudes

The study of leadership exchanges is extended by studying both leader-member exchanges (LMXs) and coworker exchanges (CWXs). Data from 110 coworker dyads were used to examine relationship.,; between LMXs and CWXs and between exchange relationships and work attitudes. As predicted, the interaction between 2 coworkers' LMX scores predicted CWX quality for the coworker dyad. Also, after controlling for LMX, greater diversity in a worker's CWX relationships was negatively related to his or her organizational commitment but not job satisfaction. The quality of a worker's CWX relationships, however, did not moderate the relationship between CWX diversity and work attitudes.
