<p><strong>Abstract</strong></p><p>This study investigates the moderating effect of co-worker support in relation to workplace incivility and counterproductive work behaviour (CWB). A cross-sectional survey was undertaken with the objective of collecting data from a diverse sample of individuals employed in non-academic departments of five private sector universities located in Lahore, Pakistan. The data pertaining to workplace incivility, co-worker support, and counterproductive work behaviour (CWB), along with several control variables. Regression analysis was used to assess the postulated connections. The results indicate a significant association between workplace incivility and counterproductive work behaviours (CWB), suggesting that persons who experience incivility in the workplace are more likely to engage in actions that impede productivity. The co-worker support plays a crucial role as a moderator that increased levels of co-worker support and mitigate the positive association between incivility and counterproductive work behaviour (CWB). The results explored the significance support for colleagues in universities and have adverse effect on workplace incivility. It may become a safer flight during the organisational interventions and for employees, and potential direction's gap is available for future study.</p>
