Hence, present study has attempted to measure the direct impact of workplace friendship and altruistic leadership on preventing the knowledge hiding behavior; and also, in the presence of positive emotions. The study has also checked the mediating role of positive emotions among these relationships. Target population of the study is the employees working in government sector (sample size of 496). Present study has employed quantitative research techniques for testing the hypotheses. Smart PLS 3 software has been employed to run the partial least square structural equation modeling. Findings of the study have given major indications about the positive role of workplace friendship and altruistic leadership in preventing the knowledge hiding behavior among employees. It has also been revealed that positive emotions play a significant role in augmenting the relationship of workplace friendship and altruistic leadership with the knowledge hiding behavior. A significant contribution of the study is measuring the mediating role of positive emotions in decreasing the knowledge hiding behavior in the presence of workplace friendship and altruistic leadership.
