Workplace ostracism is defined as the perception of being ignored and excluded by others in the workplace. Drawing on tenets of belongingness theory, we contend that ostracism may motivate victims to manage their impressions on others with the aim to seek acceptance. Findings from a two-wave survey study indicate that workplace ostracism is positively associated with impression management tactics (e.g., ingratiation, self-promotion, exemplification) through the mediating role of need for approval. In addition, this indirect relationship is more salient for victims who have high concerns for self-face. Theoretical and practical implications as well as future research directions are also discussed.
