My co-worker is my senior and she spends all day on chat.
For the last year, I have done the work of a manager even though I am very junior and I have even done more work than my senior co-worker. Recently my manager has been getting suspicious that I will be asking for more money so she has been taking tasks away from me and giving them to other members of the team. So when it comes to my annual review I can no longer say I do those things. However I did them for an entire year to a high standard so doesn't that count?
She has asked me to split some of the tasks with my senior co-worker because apparently she should have been doing them all along she just didn't have time. My coworker spends all her time on facebook and chat and shes good friends with my manager so nothing will come of it.
I have more experience than her in my field and often it creates a lot of tension. I am not sure how to ask for more money in my annual review and also highlight the fact that my co-worker has less experience than me and is above me and she does no work...
Should I just not say anything at all? I am so hard working and passionate about what I do that I get emotional whenever I bring it up because I am so stressed. I don't want to show any emotion when I talk about it to my boss because I want to remain strong but it's all really getting to me!
