Most psychopaths remain hidden their whole lives and rise to the top of organizations due to their intelligence, charm and ruthlessness. Unless they become killers, which most do not, they are not noticed except by their victims whom they manipulate, fire, blame, or cheat, etc.

No one should have to work in an abusive work place.
An Anatomy of Workplace Violence in Canada
One form of workplace abuse is the systematic pattern of behaviors used to gain power and exercise control over another person. The abuser manipulates his victims into meeting his needs, whatever they might be.
Many abusers are insecure, have low self-esteem, believe they are unloved and unlovable, (perhaps divorced and in multiple short term relationships) and in general frightened that their needs will not be met. Hence, they use abuse to gain control over other people to satisfy their needs.
The abuser is contrite, apologetic, attentive and charming. He will use these characteristics to manipulate the victim and others. In any investigations he will use the same technique to blame others and show himself as the victim. In this manner, the abused person is often blamed and held responsible. It is often the case the abuser truly believes he has done nothing wrong and does not understand the issues of concern brought forward by his victim.
He is manipulative, deceitful, and lacks any sense of respect for others. His only actions are self serving while pulling the wool over the eyes of everyone in the office including his superiors.
He is a megalomaniac with a twisted view of his personal history, not to mention his supposed destiny as the only worthy leader within the company.
The abuser is solely responsible for the abuse. Abuse is a choice and the abuser can choose not to behave this way. No one has the right to abuse others.

Is this same person a self-absorbed, narcissistic, selfish, know-it-all jerk?
Have you wondered how he could be so utterly full of shit, yet not change color?
Has he seen and done everything, always have something better, and know a better way to do your job?
Is he a real "I-Man"? I've done this, I've done that, always describing how wonderful he is and full of tall tales about everything he's achieved?
Must all conversations revolve around him? Must he always have the last word? Does he have the answer to everything, but the solution to nothing?
Does he make inappropriate and disparaging comments about others in the company?
Does he micro-manage and impose his views into each and every aspect of the workplace?
Must he find fault in everything just to make himself appear more important and pull the wool over everyone's eyes?
Does he take credit for everything, but responsibility for nothing?
Can he never be at fault? Does he never accept responsibility for any of his actions by lying and denying it happened?
Does he behave as if stupidity were a virtue?
Would calling him a useless tool be an insult to each and every useless tool worldwide?
Is the most reliable way to test for lying merely to check if his lips are moving?
Is he a vindictive SOB? You're either on his side or you're the enemy.
Rest assured your experience is not unique. Given time, his halo will eventually slip and choke him.
He's likely really not such a bad person... at least until people realize his true personality.

Some leaders get to their position through honesty, integrity, respect, and knowledge.
Others get there through lying, cheating, intimidation, abuse, and taking advantage of others.
Hitler was really good at his job too. REALLY GOOD.

I've been asked to remove this section of my web page, but also great support that the statements hit dead on the mark from others.
If you can relate to these statements and find them offensive perhaps you should. Otherwise what's the problem?
