In my experience, the issue is that performing at the next level is not a guarantee for promotion. So when you do work at the next level, they can just say “it’s not sustained enough” or whatever reason and then you’re stuck — can’t really produce less so you end up looking for a way out because all that work was kind of for nothing. I look for opportunities outside my job requirements to learn and grow but it gets really tiring and exhausting when you’re not rewarded for it. Basically there is a lot of upside for the employer but for the employee it’s a bit of a crapshoot
