Calling someone a "", violates UPS's non-hostile work environment policy. It also falls under Labor Laws, such as harassment. I don't allow anybody to talk to me in any hostile manner, because that's not what I go to work for. I go to work to do my job and get the hell out of there! Don't allow anybody to speak to you like that! It's wrong in more ways than one, and if you allow it, it's just going to get worse and make you very uncomfortable during time there.
I would take all the actions available to you, in order to have this supervisor punished in as many possible ways that are available! DO NOT TOLERATE THIS CRAP!!!
