I'd suggest to let them abuse you.

I have on several occasions tried to stop the lies and the abuse, and it just ended up 100x worse. Nothing was ever solved EVEN if I had witnesses with me high up in the hierarchy. They effed over those as well.

They lied about me many times. Of course, since I am "crazy", if people said or did something it never happened, the crazy person must have dreamt it up.... you know...

You are POWERLESS in that situation.

And most likely you will never win.
