He was allegedly harmed. If, as the person you are replying to speculates, he was freaking out and being a bad employee after discovering the affiliation of his coworkers, then potentially that's a righteous firing and he wasn't harmed in a legal sense. If as he alleges, he was fired for having valid concerns, then yes, harm in a legal sense.
