In the authors' random poll of 1,000 working people, 80 percent said that a single coworker contributed significant stress to their workday. Everyone has worked with someone "difficult" - someone who could always be trusted to blow up or say or do something provoking or inappropriate. Psychologists Alan Cavaiola and Neil Lavender have studied this much-discussed but rarely addressed area. Their research showed that the conventional wisdom that some problem workers are "just nuts" was right: a sizeable number of such employees do in fact have full-fledged personality disorders. In Toxic Coworkers, they pinpoint a variety of personality traits and disorders, showing how they come about and offering effective strategies for coping with them. The authors cover the range of familiar types, from hyperactives, histrionics, and sociopaths to narcissists and obsessive-compulsives and provide concrete techniques for surviving them.
