If you work at a company with a competent HR department they will be very interested in hearing about how your supervisor is forcing you to eat lunch with her while she interrogates you about your sex life. That is 100% not appropriate in HR world. Just don’t ever believe anyone in HR is actually your friend, stick to the truth always, and document everything. Literally, keep a log of everything. If you end up in lawyer world they will be very happy that you have documentation of dates and who was there and what happened.
That’s a dangerous path, and also very likely unconstitutional in the US.
