When someone is being subjected to abuse in what is supposed to be a professional setting, the correct strategy for them is to take matters into their own hands and probably begin a disruptive and draining conflict which they are almost certain to lose in the end because the deck is stacked against them. Under absolutely no circumstances should the victim ask for assistance, because that would demonstrate weakness and a lack of self-respect. If only the victim had better strength of character, they could put those assholes in their places and nothing like this would ever happen again.
I really don't think I can make myself see the world that way. I don't think I want to.
