I work for a small company (less than 15). There is a coworker that has, from the day I started, constantly and daily harasses me. Calling me "fat, "stupid", "slow". He constantly talks about hating Jews, he is German. Constantly tells another co-worker that "he likes to suck dicks", "likes a big dick in his ass". His words, not mine. Not just every once in a while, but all day, every day. I have approached the managers about this situation, they are aware of it, but told me to "grow athicker skin." Since I have approached management and they will do nothing, do I have a civil case against them?
