A little context: My co-worker (F40) is a little bit weird around me (M22). She is always very touchy feely with me, whenever I’m walking by she playfully hits me if nobody there, she’ll playfully insult me, ect. I’ve never really said anything to her because I didn’t think it was too much of a big deal, however I’ve never acted this way back to her, I tend to ignore her most of the time. This has been going on for around a year now but my other co-workers are only just now coming out and telling me that they think she has a weird thing for me. I do think this is a little strange do to the age gap, but she doesn’t particularly act like a normal 40 year old, in some ways she has the mind of someone in their early 20s.

Anyway, the other day I was starting my shift at work and she was starting at the same time as me (nobody else was around in the locker area). I was at my locker and due to my locker being at the very bottom, I have to kneel down to get my stuff out. And before my co-worker passed me to go to her locker, she playfully kicked me while I was knelt on my knees. I responded with saying “Oh fuck off” jokingly, and continued to take my stuff out of my locker. And then as she was walking by me, she stopped, got very close to me and sat on my head. When she was sat on me she started shaking her ass side to side on my head. I was in massive shock thinking did she really just do that. I pushed her away by her leg and said “What the fuck are you doing”. She laughing as if it was nothing and then continued walking to get her work stuff.

I haven’t brought it up with her at all since it happened, but I did feel very uncomfortable and pissed off when it happened. I have told 2 of my work friends about it and they both said that sounds really inappropriate in the work place. (They’re also laughing because that happened to me aswell). What should I do going forward?
