Sorry to abuse AIBU. I just really need some kind words.
I work for a company where my department operates autonomously and is fairly new but the overall company is huge, listed and one of the best in the world for what we offer in professional services.
I moved to the company 18m ago. I think I've done well. I'm 26 and was brought in as an experienced hire, I used to work at Big 4. Most people were brought in as graduates, working their way up. It's customary at the lower levels to be promoted every year, they aren't normal promotions as most would consider, but there's levels within each grade and you move up a level each year, sometimes 2 levels if you do well.
I just found out I didn't get promoted. They said they love working with me, I am good, but they think I could do with an extra year in my current level to gain experience. I think they needed to show the US HQ they were keeping costs down and I was an easy target. In a normal year I would have been promoted, I was told. Everyone else has been promoted, some doubles. As a result, people less qualified than me and younger are now above me (as they began as grads). For the job you need to be ACA qualified, grads do this in their first 3 years. I have been qualified for 2 years, so that's what I mean by qualified.
I feel so worthless and embarrassed. I don't want to stay but a part of me wonders if maybe I should for a while. I get paid a good amount and I have it pretty easy right now.
Any words of advice?
