Punched at Work
I'm a middle aged woman and have been working with my company for 8 1/2 years. My boss's admin has been trying to intimidate for the last two months. We used to be friendly.
In August we were in the hallway talking about a TV show we both like. Someone was coming down the hallway and she had her back to him. Since we were in the middle of the hall way I said - watch out. My meaning was I wanted us both to step aside to let him pass since we were taking up the space in the hall and no one could pass us. She took offense to that. Started yelling at me. I tried to explained myself and she stormed off. Later on in the day I went over to her and spoke to her. We each explained ourselves. She told me she doesn't move over for anyone and I said I was just being polite. She suggested we agree to disagree. We shook hands on that and I thought the matter was resolved. I took the high road and was nice to her. She would ignore me unless someone else was around. She would glare at me and tried staring me down when she saw me. I continued to ignore it and continued to be pleasant to her.
Then on Monday morning we were on opposite sides of a glass door. I stepped aside to let her through first - which I would have done regardless of who was on the other side of the door. She opened the door and her face contorted and she hit me on my hand. My arms were down and my hands were at my side. I was taken aback and said "you just hit me" her response was "I have no idea what you're talking about" and walked away. The receptionist was there but when I asked her about it she said she was looking at her computer screen and didn't see what happened.
My question is should I try to reason with her, report her to management or let it go. I think she is emotionally disturbed and fear her behavior will escalate if I say something.
