Moreover, a relational psychological contract breach is a mediator between workplace conflicts and knowledge-hiding behavior. For empirical evidence, data were collected from research and development institutions in Pakistan. The results confirm the significant association between conflicts and knowledge-hiding behaviors and the mediating role of relational psychological contract breach. The objective of this study is to investigate the impact of workplace conflicts (interpersonal conflict and task-related conflict) on knowledge-hiding behaviors (evasive hiding, playing dumb, and rationalized hiding). Besides, a relational psychological contract breach is used as a mediator between workplace conflicts and knowledge-hiding behaviors. By using a simple random sampling technique and time lag strategy, the data were collected from 408 employees working in research and development institutions in Pakistan. For analyses, this study employed partial least squares structural equation modeling statistical technique by using SmartPls-3 software. The results of the study confirm the significant relationship between workplace conflicts and knowledge-hiding behaviors. Relational psychological contract breach also significantly mediates the relationship between conflicts and knowledge-hiding behaviors. However, this study found an insignificant association between interpersonal conflict and evasive knowledge hiding.
