This man would be doing nothing to get anyone fired. Tristan would be informing a company that one of their managers and his direct report (who happens to be married) are having an affair. This is verboten in most companies because of the possibility of a sexual harassment suit. The employer can take any action that they deem necessary to protect themselves. And if the Company decided it was in their interest to terminate one or both of these people, well there are consequences for behavior. The truth of the affair isn't the problem. The problem is the affair itself.
I would fight this with my last breath.
I'm a man . . . But I can change . . . If I have to . . . I guess . . .
