So I have a coworker that's been ignoring me to the point it makes me feel uncomfortable. I've tried to confront him on this and all I got out of them was I “snitched him off to the boss”(one time weeks ago, he was late opening and I called the manager unsure of what to do). I've repeatedly asked my manager to schedule me different days when he's not working but he keeps scheduling me for weekends(which is when he works). I'm not sure what to do about this and I kinda need this job right now so I can't quit. Should I go over the managers head and contact HR? Or the owner? I don't know what to do and I feel trapped. Any advice is appreciated.
