In every state of this country, in every city, this kind of behavior is illegal. Do you have a small voice recorder? The next time he approaches you, record it. Do not laugh or make light of it and tell him firmly "NO" and to get lost. Then tell him that you are going to the boss with the recording and if he says one more word about this, you will also go to his wife (or girlfriend or whoever she is) and give her a copy of the recording. This is no game. This is illegal and is a violation of your rights as a woman and as an employee and as a citizen.

For your sake, I do hope that you get the other job. I am not going to give you false hopes. In my work in the government many years ago, we successfully saw many people prosecuted for this crime but the fallout was also real. It's gotten better but it hasn't disappeared completely.

Stay strong and stand up for yourself. Hugs to you and keep us posted.
