I worked for an employer who had a hard % cap on pay increases which made it extremely hard for them to retain people that they promoted from within. I don't recall what that % was, but it wasn't that much maybe 10%? What would happen is people would work for them for x number of years, get a new position with a new title that should increase their pay by say 30-40% at a minimum, however due to their pay increase cap it would have to basically get C level approval and even then they'd only increase the pay by ~25% at the maximum. People would then update their resume and start looking for a new job with their fancy new title and take a job elsewhere. Some would wait a year or two and come back at the correct pay scale. This problem wasn't the case with the entire company, but in my situation I had accumulated a wealth of institutional knowledge and was in a situation where I should have been making ~40% more than I was getting paid so I left knowing I could always go back if things didn't work out. The last time I drove by their offices they were flying a faggot flag so the chances of me being willing to work for them again are pretty slim.
