Dark Personalities: Their Role in the Creation of Toxic Workplaces

Individuals presenting dark personalities such as narcissism and psychopathy can have devastating effects as employees, but these effects are even more significant when they are in a leadership position. Indeed, an organization’s culture is created and maintained by its leaders. When those leaders present dark personality traits, their values, and negative workplace behaviors set the tone for a toxic work culture.

We will discuss how individuals presenting dark personalities make their way into the organization to obtain leadership roles, how they are able to remain in those leadership roles despite their unethical decisions and behaviors, their influence on toxic work cultures, and how to deal with the root causes of toxic work cultures (leaders and systems).
