There is a man at work that is accusing my husband and me of chasing him around town on a motorcycle, wearing clown suits. While this may seem humorous, he is serious. He has not said anything to us personally, but he stares me down at work and uses gestures to intimidate me. My personnel department says this does not constitute harassment because he is not coming against my gender or race. He makes me feel uncomfortable and I say this constitutes a hostile work environment. What can we do?
