Pardon my bad news but this is NOT something to mess around with.
HR is NOT your friend and hasn’t been for almost 20 years.
It is an engine to protect the company and push an agenda.
I nearly got fired 10 years ago for doing something much, much less disruptive than what you document.
You are already in deep trouble...don’t make it worse.
Get some professional legal help and GO TO GROUND.
Well said.
