Dr. John Clarke, an expert in the criminal mind, discovered that psychopaths are not only people you'd find in prisons or in the courtroom. They are lurking and scheming in workplaces world-wide. They lie, cheat, steal, and they manipulate, victimize, and destroy co-workers.
The problem for their victims is they are very good talkers and appear to be charming and intelligent. Their ruthlessness is mistaken as ambition and a drive to succeed. In a way it is. They will do anything to get what they want--power, salary, status.
According to Dr. Clarke, the workplace psychopath thinks the same as the criminal psychopath. The difference is criminal psychopaths physically destroy their victims; whereas, workplace psychopaths psychologically destroy their victims. I would add that the health of workplace victims is often seriously compromised for the long-term due to intense and prolonged stress. Indeed, workplace victims often feel their lives are destroyed.
Clarke says there are two weapons you can use: education and teamwork. Education helps you recognize what is happening and empowers you to stop the self-blame. Teamwork keeps you from becoming isolated.
Build a personal team advises Clarke and tell people what is taking place, because "if a psychopath can't isolate you, he can't destroy you."
