Just to add - this can even be a career advancement hurdle. My mom told her about a meeting she had with her boss where she asked for a promotion because she was doing so well at her current role and the boss basically said "yes you're doing more than we've seen before and that's why we're going to keep you right where you are". I'm a bit wary of the "peter principle" where people generally get promoted until they can't do their job well - but that's an institutional concern. From the perspective of an employee it might make sense to not excel because it could make you too valuable to promote. One of those annoying contradictions where you might have to look out for yourself at the cost of the company you're also trying to help succeed
