I've dealt with this type of abuse all my life to the point where I'm so worn out from confronting ppl I either tell the boss to keep the asshole away from me or I just walk out..if your in a good job it's hard to walk out & just say your quitting especially when u have bills & can't get another job right away. But yeah I would confront the prick & say you don't play that shit. If he comes back at you which has happened to me at lower paying labor type jobs & gives a attitude or gets aggressive walk out and call your boss saying if he doesn't sort this out your gonna have to contact your lawyer...Don't take this lightly like I did at first it's killer for your mental health..it lead me to substance abuse, intense depression & anger issues from years dealing with insensitive toxic ppl...don't start a confrontation but definitely do what's best for yourself buddy. This type of abuse should never be tolerated in the workplace.
