Jealous of a colleague

[Kandymuse70]

I know it's a horrible emotion and irrational, not here for people to have a go.
I work at a school, I was doing the role she now does as a maternity cover, and then a permanent role was advertised.
I applied as an internal candidate, but she was given the job as an external.
It's my own problem, I just feel resent that I was already doing that role myself yet they didn't deem me good enough to do it permanently.
Anyway, I guess I am jealous, I have another role now but on a much lower salary. I always see her walking round in expensive-looking clothes and she seems to have made a lot of friends at the school.
I covered one class of hers and when the kids came in they didn't even say hi or anything, just asking why she's not in and looking annoyed. Ended up telling them to just deal with it as it's just one day and not the end of world.
It's wrong to compare myself and all I can do is better myself. I have taken on a second job which will give me a much more comfortable salary.
I just need to focus on myself, I recognise this is irrational.
She has never been rude to me or anything though once she seemed to give me an order.
Any advice would be appreciated. Have others felt this way ?

Oh OP, so sorry you are feeling like this. Comparison is the thief of joy as you are finding.
Please try to be a bit kinder to yourself: as PP have mentioned, it’s worth getting feedback about why you didn’t get the job, as your current feelings might be showing (Eg. In your body language) and holding you back. A frank discussion with your manager should point you in the right direction.
As for her “expensive clothes” - many people that look expensive do so only because they only buy clothes that fit them perfectly, or have them adjusted after buying a size too large, or accessorise really well. Have a look at some articles online for how to do this - my Sainsbury’s dress costing £10.00 in the sales has garnered me the most “Ooh, you’ve dressed up today” comments after I had it tailored to fit (which cost me £15.00). That confidence is what you’re after, once you have found your way to this, you’ll stop being jealous and it will show🙂

you sound quite bitter and jealous and it comes out in your post by the way you spoke to the class, thats unprofessional and probably why you were not considered for the post you wished for.

So what if this new teacher shops at selfridges and you dress in Primani, lifes too short to worry whos wearing the most expensive blouse.

Take a look at how your behaving and work on being more positive, it will go a long way
