A male coworker frequently threatens to knock anyone out that is doing their job. If you enforce a corporate rule he will bait you into an argument and threaten to knock you out. Manager just coaches everyone, even the victim in the situation. No formal punishment.
Today as his boss he was hinting around at fighting me and called me names because I refused to argue. My boss did nothing. What rights do I have?
ETA: he told another coworker and customers they don’t make enough money for him to knock them the fuck out
