9. The employee has everybody fooled.
In their book "Snakes in Suits," Paul Babiak, Ph.D. and Robert D. Hare, Ph.D., explain that a surprising number of workplaces employ psychopaths.
While psychopaths make up 1 percent of the general population, Babiak and Hare found that 3.5 percent of the executives they worked with "fit the profile of the psychopath."
Psychopathic employees are pathological liars who get away with doing little or no work. They charm senior management with their "leadership potential," con co-workers into covering for them, and successfully blame others for their mistakes.
If you're the only one who sees what they're up to, you're in a tough spot. Sometimes it's the whistle-blower who gets fired, not the snake.
