Psychopathy in the workplace
While psychopaths typically represent a very small percentage of workplace staff, the presence of psychopathy in the workplace, especially within senior management, can do enormous damage. Indeed, psychopaths are usually most present at higher levels of corporate structure, and their actions often cause a ripple effect throughout an organization, setting the tone for an entire corporate culture.
