It's extremely difficult to be promoted to a higher pay scale without jumping ship and jumping into a new role altogether. Once you're in a role, there's a glass ceiling until you go to another department. Also, they don't pay people who are transferring from inside to outside roles with comparable pay to what they would pay direct outside hires from outside the company. Finally, new performance criteria leads to a very short leash for those who don't meet the ever-increasing growth numbers which are based on historicals, which can be difficult if you had a superb year the prior year, but cannot repeat your uncommonly high attainment.
