Someone already said that above you so I'll quote "you don't have the right to not have your feelings hurt" and if you can sue over this in Claifornia, it might be one of the reasons 3 Californian cities have already gone bankrupt.

People are so sue happy in America, it's ridiculous. As stated in the united states constitution, OPs boss does still have freedom of speech and expression - he was verbally expressing his apparent deep loathing of OP. Totally acceptable. Saying that you can sue for this is just as stupid as those fatties that sued McDonald's because "it made them fat." I mean really? Common sense should've told them that if they constantly engorged on fatty, greasy food, they would eventually get fat! Seriously, Americans - stop with the suing. You're making us non-retarded Americans feel ashamed.

Unless he was not doing his job or meeting targets or violated company policy. Just coz he was fired in a shitty way doesn't mean the firing wasn't jusified

oh wow look at all those question marks! You must have a huge penis /sarcasm

It is impossible to sue them! You are the third idiot who has said this. This isn't harassment, sure it isn't nice, but it is in NO way grounds for a lawsuit.

You'd be hard pressed to find a lawyer that would even take that case. Most of them would laugh you out of the office and still charge for the consultation ;)

If people were sued every time they did something wrong, all of us would be bankrupt.

Sue happy people need to get their arses kicked. Medical malpractice? One thing. Car accident that's not your fault? Another thing. Somebody called you names? Shut up and grow up.
