go to HR, If you don,nt. and something goes wrong you will be screwed. If I was your super and you told me this, I would go with you and talk to the HR manager. I would also have to right up a report. and bring that with. Not you, me.
Do not talk to any other team members about it. I can not stress that enof. Not now, not after going to HR and not after, ever.
Let HR handle it, may be she just needs some training on how to act in a professional setting.
