Perceptions of co-worker exclusion and performance outcomes: are different forms of support helpful or hurtful?

Abstract

Abstract We argue that social support can be helpful or hurtful in the context of performance outcomes for employees experiencing co-worker exclusion. We contend that employees' perceptions of co-worker exclusion are negatively associated with task performance and citizenship, and positively associated with interpersonal deviance. We further contend that whether social support strengthens or weakens the negative performance outcomes of co-worker exclusion depends on whether the source of social support is from co-workers or family and friends. Using data obtained from 135 supervisor–subordinate dyads across various occupational positions, we find that co-worker support is hurtful, whereas family and friends support is helpful. We also find a three-way interaction: task performance suffers most when employees who feel highly excluded also perceive higher co-worker support and lower family and friends support. These results suggest a need for a more nuanced view of social exchange/support, and build our knowledge about ambivalent relationships.
