I've nced for obvious reasons.
I work in an office which also has a warehouse. The manager of our branch has his son (16/17) working with us to help out as we are short staffed. Me and the manager also work together but he's still higher up than me. He isn't trained to do most of the work in the warehouse yet so he just give them paper work etc and helps them out. He seems nice so thats not an issue.
However, when he first started properly, he was flirty, one time he also tried to kiss me. I asked him what he was doing and he seemed embarrassed and apologised and he asked me not to tell anyone.
Things were ok after that but recently he's been staring at me and I sometimes notice he's looking at my chest. I also feel uncomfortable if I'm alone with him. My manager has meetings at other places a lot so he asks me to tell his son what he needs to do, I don't have an issue with this but he comes to my office a lot. Yesterday, I also noticed he was smirking at me. Later, he asked me if I was single. I told him I didn't want to answer that and he said he was just making conversation.
Aibu to feel uncomfortable and am I overreacting?
