So I've been working with this colleague for about a year when she joined. I have been there for 5 years prior. We work in education. I'm not with her constantly around the school day but there is a part of the day where I have to be. The first couple months she was fine. Then when September came she completely blanked me and doesn't speak to me. You know when you know someone has a problem with you but you know you've done nothing wrong. I tried saying hello but nothing. So I thought okay maybe it's personality clash so I left it. It's getting worse, she will shut the door in my face if I am walking behind her, if I am speaking with children she will stand there staring as if she's my manager yet she's the same level as me, she's about 20 years old! I'm mid 30s! If I need to get past to get something I will say excuse me politely and she won't move. She even got involved when I was dealing with a child first and pushed into me trying to take over. I stood my ground, ignored her and carried on dealing with the child and she ended up walking off. She will stand there pointing over my way and looking at me so it looks like she's talking about me to others when I'm pretty sure they're not but it's to intimidate me. Almost like she's having a normal conversation with them but she's wanting me to think they're talking about me. The other staff are fine with me.
What do I do? It sounds petty when it comes out and it is petty which is why I feel like I can't go to the headteacher. I can't change where I am in the school as my job involves speaking to everybody. Its pathetic what she's doing. It didn't bother me at first but now it's happening more often. Has anyone else been through this?
