Toxic leadership is an area of growing interest. The goal of my study was to investigate toxic leadership and how toxic leader behaviors relate to employee outcomes. Part of my goal was to examine the role of toxic leadership (taking other factors such as burnout, and workplace incivility) and how toxic leadership and other variables contribute to an employee's subjective well-being. Hence, the goal of this study was to examine the following effects: Toxic leadership behaviors and their effects on subjective well-being of the employee; and b) mediating roles of incivility and burnout on toxic leader behavior and the employee’s subjective well-being. Data were collected through snowball sampling and a paid survey through MTURK. A random sample of 339 working professionals completed the survey that assessed how different aspects of an employee’s life are affected by toxic leadership behavior. Burnout, incivility, and subjective well-being were assessed using existing measures in peer-reviewed publications. Each of these factors were measured using their respective scales. Data were analyzed using linear regression via SPSS v.28 to find the direct relationship of toxic leadership behavior and its effect on employee’s subjective well-being. Results indicated no significant relationship between toxic leadership behaviors and subjective well-being. Results also indicated there was a significant relationship between toxic leadership and burnout. Findings from this study also highlight a new and significant relationship between toxic leadership behaviors and incivility.
