"I have been raped by a colleague — not just once, but several times over months."

As much as I want to read this as hyperbole it doesn't look like that's the case. I guess it may be because I consider myself a level-headed person, and have (to the best of my knowledge) never even interacted with someone that vicious.

A person like that doesn't deserve just to be reprimanded. They should be in jail.
