The disadvantage to working for a company who owns around 25% of the market it operates in is that there's not much growth to be had, as people are afraid of locking themselves or causing a monopoly position. This lack of growth though leads to freezing the available budget to last years level.
Now, the main issue with this is that, basically, there's the same amount of money available to the same amount of people. Doesn't sound too bad, right? Well, each year you're evaluated based on your performance. This means that that some people need to get promoted, and in turn earn more. All of this with the same overall budget as last year. So yeah, this in turn means that some of the eployees will have lower salaries compared to last year, despite the company doing well (maybe too well).
I just hope I'm not one of the unlucky ones. God, I hate performance review week.
