Yes, and this goes for a lot of things. You can sue even if the other person was really clever. I mean, these are like, 12 year old boy logic. "Ahh I'm not touching you!" while they wave their hand in your face. That doesn't fly in the legal world. Also, just because you sign a contract doesn't mean you can't sue either. You can! Many, maybe most, contracts are invalid. You can't just write down whatever and make the other person do it. You can fight non-competes, NDAs, you name it. Also, if you got fired for "performance" (air quotes) that doesn't mean you can't sue. You can! Most discrimination cases occur when someone is fired for "performance". HR isn't stupid.
