I had a colleague some years ago when my kids were primary school age - who used to constantly make snide and sarcy remarks every time we went to the cinema, the theatre, out for a meal, on a day trip, and especially on a holiday abroad ...
She was about five years older than me so in her late 30s at the time - and always single .... She had occasional boyfriends for a few weeks, but never managed to keep hold of any of them lol ... it's probably because she was a nasty spiteful cow to be honest with you ...The amount of remarks she made towards me was outrageous .. Never anyone else just me.
...... 'oh it's all right for you isn't it being kept by a husband' (I worked 22 hours a week at the time, and did 90% of the childcare, housework, home admin, grunt work etc, so not exactly fucking KEPT.
) And she said 'yeah it's all right for you double income families - and YOU having a husband who brings in loads of money so you can have a good life .... what about the single people - do you ever think about THEM when you're swanning off doing stuff?' And she often said when I left for home at lunchtime (I did 2 full days and a half day,) 'slacking off again part timer?!!!' She was a fucking bitch.
She constantly goaded me and got at me too, critisising everything I did, and mocking and deriding things, like when DH got me a lovely soft toy from Steiff for my birthday, she laughed and said 'are you 5?!' Her jealousy and resentment towards me was fierce. Because I worked part time, and had a husband, and 2 gorgeous kids. (Everything SHE wanted.)
HILARIOUSLY - she was actually a supervisor, and her income was about 10% more than mine and my husband's combined! Plus our mortgage at the time was £550 a month and hers was only £300 cuz she brought a council house on right to buy for about £15,000 compared to the £42,000 we paid for ours ... (Very late 1990s.) She was such a nasty bitter little cow ... 😆 Even now I see her out and about ... She's in her early 60s now, and she's still single ... LOL can't imagine why.
@MojacarSunset YANBU, what your workmate is doing is tantamount to bullying. When this horrible colleague of mine was so vile, I did report her to the manager, but she was above me in rank, and right up his arse, so he just told me to grow up and stop being a wimp. Charming.
This was 22-23 years ago. I doubt it would be allowed to happen now. She was a bully. She left eventually after a MALE colleague got the Office manager job she went for, and said it was only because she is a woman that she didn't get the job.
She moved onto another company, and I heard shortly after (maybe 5 months later,) that she was busy making another young mum's life hell, bullying and goading her, and picking on everything she did. This young mum left after 5 or 6 months of it, as she couldn't stand the bullying any longer, from this vile bully who left my place of work..... As I said, no wonder she is perpetually single.
