In this paper, we examine how narcissistic supervision and workplace bul-lying affect job wellbeing and employee silence through emotional exhaustion and psy-chological contract violation in order to address gaps in recent research and highlight the effects of adverse working conditions on performance behaviors of employees. We conducted a pilot study involving data from 51 employees in the fast food industry and performed confirmatory factor analysis. We then collected data from 616 employees to assess the relationship between the study variables. Results indicate that perceived narcissistic supervision and workplace bullying have a direct positive relationship with employee silence, and a negative relationship with job well-being behaviors. They also reveal significant indirect relationships between the variables and support our hypoth-eses. These insights contribute meaningfully to academic literature and have practi-cal implications for organizations striving to address the challenges posed by negative work environments. We highlight limitations of the study and provide future recom-mendations to enable researchers to assess the generalizability of our results.
