Collection of data was made through a survey distributed to 249 call center employees in Lahore, SPSS was used for analysis, including descriptive, reliability, correlation, and Harman’s one-factor analysis. The findings of this study show that psychological contract breach negatively affects LMX quality, and mindfulness moderates the indirect effect of abusive supervision on LMX through psychological contract breach. These results contribute significant insights into workplace dynamics, focusing on the importance of mindfulness in reducing negative impacts. The study illustrates the significance of leadership’s role in employees’ relational outcomes.
