How does a counterproductive work situation affect employee turnover intention? Using conservation of resources (COR) theory, this study explores how the experience of workplace ostracism results in knowledge hiding and turnover intention. Based on three waves of data collection from several organizations in Indonesia, we find a support for our proposed model. Furthermore, this indirect relationship was stronger among employees with higher level of hindrance stressor, in contrast, was weaker among employees with higher level of challenge stressor. We conclude this study by discussing the theoretical and practical implication of these findings.
