PAY. They want to give them easily 3% a year so you are making less money each year because inflation is usually higher than that. The only way to get more money is to gain some experience and training through traumatics and then leave to an OEM or something similar to get paid what you're worth. Just causes a lot of turnover and it's very hard to find new people with any experience so you are constantly doing the job of multiple people. It's a vicious cycle all because they don't want to pay people what they're worth as they progress in their career instead they would rather wait until the next guy comes in pay him even more than someone was asking for plus they still have to send him to all the trainings that the other guy had already completed. Just a poor business model that makes no sense to me.
