Recently, I’ve had a coworker of mine misbehave with me multiple times for absolutely no reason that I can think of. My only interaction with them is when I go to give them their lunch break of 20 minutes, twice a day. That’s literally it. Their misbehavior includes yelling at me at the top of their lungs, calling me names, passing rude comments as I walk by and a few other methods of being very aggressively rude.
I have notified and complained to my boss about it every single time and he has not a single care in the world except to just give me additional work and literally say the words “I don’t care”. Keep in mind this coworker is a temp, super junior compared to me and also works at a lower level on the company “ladder”. I happen to like my job. I also complained to HR about it and to my “NOT” surprise, his solution was to further misbehave with me and tell me that the issue is in my head. I have had multiple people witness this coworker’s demeanor with me and they all agree.
I need advice on how to deal with this further. Any help would be greatly appreciated. Is this something I could take to an organization like the Dept. Of Labor or something similar to that?
