Abstract
The concept of workplace ostracism and employee silence has achieved considerable attention in field of organizational psychology in recent years. This research examined the relationship of workplace ostracism with facets of employee silence i.e. acquiescent, defensive and diffident silence with mediating role of perceived self-esteem and meaningful existence in teachers of Public sector universities in Punjab. Data were collected by 200 questionnaires distributed to university teachers serving in Public sector universities in Punjab selected by cluster sampling, out of which 159 usable responses were received. Regression analysis and Preacher and Hayes (2008) mediation test were used to analyze data by SPSS 20 Software. Results revealed a positive association between workplace ostracism and employee silence whereby meaningful existence and self-esteem partially mediate the relationship between workplace ostracism and employee silence.
