Thanks for the answer. I hope all firms have a formal HR process where they state expectations and confront the individual before he is labelled as toxic. I think everyone should have a chance!
Well, for truly toxic individuals, warnings or confrontations are useless (I’ve learned this the hard way, and not for lack of trying). It is impossible to get them to understand that they have a problem; anything you say, no matter how clearly articulated, fact-based, and objective, will be rationalized away. These individuals cannot accept that they may be wrong.
