An increased interest in the impact of the so called "Dark Traits" of personality (e.g., narcissism, Machiavellianism, psychopathy, sadism) on the organizational well-being and job performance has been observed during the last ten years, aiming to lead to a better understanding of phenomena like toxic leadership, abusive supervisor behaviors and corporate psychopathy. These Dark Traits are usually expressed through behaviors characterized by manipulativeness, deceitfulness, callousness, hostility, and antagonism, as well as irresponsibility and risk propensity. We review the existing evidence on how these Dark Traits affect positive and negative aspects of workplace well-being (e.g., burnout, work-engagement etc.) and organizational performance (e.g., absenteeism, turnover intention etc.) and propose directions for future research.
