"...Sue should heap a sexual discrimination suit on top of the severance."
Given what we know, there would be virtually no chance of her winning such a suit, and it might only make it more difficult for her to find another job. She'll probaby be replaced by a woman, so the sexual discrimination claim would have no support. Plus, her on-air 'F-bomb' would probably give them whatever justification they need. Stations hire and fire all the time, and proving discrimination would be a challenge.
