Workplace ostracism and knowledge hiding are pervasive issues that can negatively affect organizational citizenship behaviors (OCB) among employees. This study's purpose was to examine the individual relationships of workplace ostracism and knowledge hiding with OCB in the Pakistani context. A cross-sectional survey was conducted with employees across various industries in Pakistan. The data were analyzed using regression analysis to test the direct effects of workplace ostracism and knowledge hiding on OCB. The findings provided insights into how these harmful workplace behaviors undermine extra-role behaviors that are beneficial for organizational effectiveness. This study will help identify the drivers of key workplace behaviors and inform managers on how to mitigate the detrimental impacts of ostracism and knowledge hiding.
