I always wonder at what point does bullying and the like become genuine illegal harassment? I have worked with assholes who bullied and acted like children, but I dealt with it and moved on. If my wife had worked with the same person does that make the bully's actions now something that is illegal?

I've done some reading on this and it is never quite clear. It seems like if the asshole is an asshole to everyone it is fine. Only if they pick a protected class to be an asshole to does it become a problem.
