There is a guy at work 2 heads taller and more muscular than me I find very strange: he seems to enjoy to either ask or tell me what he thinks about me without any filters: He either asks intrusively if everything is OK, staring at me like it’s an interrogation or blurts out loud what he thinks about my face (you look angry). It’s always when I’m preparing to do my job (checking the computer, taking notes) or when I’m working (looking for files). I’m starting to feel intimidated. I don’t talk to him but he talks to me, I don’t want to talk to him to listen what he thinks about me. Can’t he see I’m working? Doesn’t he have things to do? Or anything better than blurt out what he thinks about me?

I’m also a man, but smaller than him and I keep my opinions to myself.

Is this mobbing? Would contacting HR be of any good? Any ideas to deal with this kind of person?

This has happened twice already in 3 weeks, so you decide if this is a pattern.
