i've been in current role for 4.5 years, the most junior person in a team of 5. 2 years ago, my colleague left and I took on all her workload. I was happy to do this to get more experience. I was given the news last summer that I would be promoted to her role within 6 months. A few months later I was told someone would be recruited for my original junior role. 6 months later, nothing happened and I asked my manager if promotion was going to happen soon. She nodded but I thought she seemed unenthusiastic. Now I've been told it's not happening for a while.
I feel very upset and disillusioned. I have put in a meeting with manager where I will set out my case for promotion. The thing is, if she says no, or if she says it will take another 6 months, I just want to tell her that I think it's time to move on. I don't want to wait another 6 months, even if they tell me in writing this time.
It's a great job otherwise and I feel like I'd be cutting off my nose to spite my face, but I just think they've had me perform the work of 2 people over the past two years, given me consistently good/excellent feedback in appraisals and now just want to save money by continuing to have me perform both roles. AIBU to feel this way?
