This study delves into the intricate relationship between leader narcissism, stress levels, and organizational communication, providing insights into the dynamics of contemporary workplaces. Utilizing a sample survey conducted within an information technology department, participants assessed leader narcissism, job stress, and organizational communication through comprehensive questionnaires. The findings illuminate the positive correlation between the "exploitativeness" dimension of leader narcissism and the "work-family conflict" sub-dimension of job stress, as well as the "feedback" sub-dimension of organizational communication. Similarly, a positive association emerged between the "superiority" dimension of leader narcissism and the "critical communication" sub-dimension of organizational communication. Conversely, a negative relationship was observed between the "self-sufficiency" dimension of leader narcissism and the "information sharing" sub-dimension of organizational communication.

Moreover, a statistically significant negative correlation was identified between the "authority" dimension of leader narcissism and the "role ambiguity" sub-dimension of job stress, while a positive relationship was detected with the "role stress" sub-dimension. These empirical findings underscore the nuanced effects of leader narcissism on job stress and the quality of organizational communication within the workplace. These significant insights offer valuable implications for leadership practices and organizational communication strategies, empowering organizations to address the challenges associated with leader narcissism. The scholarly contribution of this study advances the field of organizational behavior, providing actionable recommendations for leaders and managers striving to cultivate a conducive work environment.
