Hi,
Apologises for long post, first time poster here.
Having difficulties with a fellow co worker
So I'm a male in an admin position, and I have been in my current role for a just under a year, I'm well liked by my co workers and senior management, apart from one, there's this female there who also works in admin, she's in her 60s and she thinks I'm incompetent (I passed my probationary period and been given good feedback) so I don't believe I am incompetent, she used to be in a position of authority but now for whatever reason she's not and she is same rank as me, but that doesn't stop her from deciding she thinks she can tell me what to do and order me about, I've openly told her to her face I don't like how she speaks to me and she gave me a very long patronising speech about how she prides herself on professionalism etc, and since then she's been very cold about me and I have heard her bad mouthing me to colleagues behind my back, luckily my colleagues have noticed how poor she treats me so don't really take notice of her. Management is also aware and I have been praised by them for my professionalism when working with her.
Basically for somebody who apparently prides herself on being professional I believe she can not accept the fact that me 40 years her junior is there in the same rank as her and seeing the fact that she is no longer in that position of authority and she can not tell me what to do, hasn't stopped her trying however and she got told off by management before for trying to order me about, but she still tries! She refuses to listen to a word I am saying to her, which makes working with her on tasks very difficult (her problem not mine) she's very rude to me and abrupt when she does need to speak to me,
I've been told that she disagrees with a few aspects of my lifestyle, for example I become a father when I was just 14 years old (but I've always held down a full time job in between balancing being a father) so that has never ever affected me and my child is 12 years old now so old enough to walk himself to and from school etc and fend for himself alone at home so I don't miss work to drop or pick up from school, she has made it very clear to me in the past we should have had an abortion or better still not do that stuff at such a young age! (It was a mistake but we decided to keep the baby and me and his mum have worked hard to give him a stable upbringing) and anyway it is none of her business and I don't need tips from her.
Anyway she's decided because of that to form the opinion i am incompetent, and that she's somehow superior to me in every way (although she claims she's never a snob) and that she believes she is a firm professional, however some of the things she's done to try and show her superiority over me at work is anything but professional!
Any tips or advice how I can best manage this please? Management are aware and they along with my colleagues are mainly in my camp rather than hers, not that I want other people to get involved. I don't wish to make a formal complaint because that will make everything worse.
Thanks in advance apologies for rambling!
