I'm not sure if this is unlawful termination, but I have a friend who was recently terminated with cause. The cause was supposedly lying about something. He had proof in his emails that proved he was innocent, but he has no access to his emails and was told all his accounts were deleted immediately on termination. What actually happened is some higher ups who had no hand in his brainchild saw how successful it was and wanted him to put their names on it. He refused (in retrospect, stupidly) and thus was fired so that they could take it over and claim it as their own. Because he was fired for cause, he has no severance, unemployment, cobra health insurance, etc. If he had copies of his emails it would be an entirely different story.
