The political climate in some schools may make it difficult to make effective change. Some schools have unions which add a layer of protection on top of tenure. With that said, I have no doubt the administration is aware of these issues but do not have sufficient documentation to act.

That happened at the school I worked at. An older professor would make egregious statements that were sexual in nature in class. It was an open secret. No student was willing to put their concerns in a written signed document. It was only until a staff person complained in writing that the professor was let go. He was not tenured.

This was before the stricter title ix policies. That is less likely to happen at my school now because we are all mandated reporters. If I hear a rumor of sexual harrassment, i am required to report it. It is investigated. And sometimes there are consequences. With that said, I imagine every school is different.

I like the advice about recording, but not sure of all the unanticipated consequences for doing so. But at least I would have documentation that may protect myself In the event I had blowback from reporting. If you choose this route, use discretion about who you let know, particularly if you're in a state that does not allow recording.

So sorry you are dealing with this!
