In 6 years working for them, I have not had a proper promotion (I started as a jr. assistant and am now an EA) with HR, just in workload. I have only received to raises in 6 years, one was 0.1% and the other was COLA, which everyone got. I have been denied more vacation time, I have been denied educational help, I'm basically stuck in a dead end job.
I will say though, I really like my fellow employees, even the ones holding me back. There is a great culture in the office.
