I have been there longer but I’m not qualified as I’m support staff. She has a qualification (nursery) she’s mentioned a few times me not being qualified. She is stand offish, stares at me a lot with a ‘mean girl’ look, only way I can describe it. Like a smirk, every time I look up and catch her eye she’s staring in that way. She blanks me whenever I’ve said hello in a morning and she just doesn’t look my way when I say it, like I’m invisible. She doesn’t make any conversation with me like she does with my other colleagues and when I’m talking to another colleague about something I notice out the corner of my eye she’s like frowning. She brushes me off if I have to ask for help and she just makes me feel really uncomfortable tbh. I don’t know how to approach it as it’s starting to make me feel on edge. What would you do? I haven’t done anything that would upset her or anything like that.
