I am with you 100%, but these are their own personal thoughts, he did reference the girls weight and one of them made a sarcastic comment, but they did not call her a name, I have heard much crueler statements. You might be able to force them to resign (good luck), but you will never be able to fire them. The comments are not that disparaging, and they may sincerely think the other girls takes drugs (and maybe she does). I do not defend their behavior, but you are not going to be able to fire them over this.
