I would work YOUR way up the HR ladder. Get the go ahead from the top and get it in writing. I would look into your rights and if you allowed to kilt up and get it in writing on a letterhead with the HR persons name on it. Then kilt up and if the boss cries then show him the letter.
I once went on a interview and saw someone I knew who worked there. Well the person/owner wrote down to find out if the person I knew and I were of the same religion (come to find out he hated people of my religion). When I went back for the second interview with the hiring manager I saw this written on the back of my resume. I plucked my resume out of the hands of the interviewer and asked what it was all about. She poo pooed it and I said I wasn't interested in working for them. I contacted a lawer and 6 months later I walked away with a few $$$$$'s and the business was closed permanently. Moral of the story: don't EVER let people take away rights that thousands & thousands of people died for YOU to have. To allow someone to do that to you is disrespectful to the people who fight to allow you your freedom.
