You wife should have been (& hopefully has been) documenting every aspect of the situation in real time. That includes each episode involving the perp. and her interactions with HR. This is just common sense. In any environment where ongoing and required interaction with other people and where negative behavior creates hostile interrelations, documentation should be (is) the first line of action. If she hasn't done this, she should sit down and document as best she can what has transpired being up front about it being a history after the fact, then begin documenting the situation in real time. Then I would consult with an attorney before taking it to higher ups and let them know I had done that as a result of lack of effectiveness at the lowest levels of reporting it.
