It's also because it's not always about growth but about adjustment to different values; ones which aren't necessarily universally better, making them a better person, but simply different.

E.g. different companies will prioritize different things and the correct behavior is contextual; for a very crude and simplified example, if some employee puts speed over correctness and the company wants them to change their behavior to value correctness over speed (or the other way around! their previous workplace might have worked hard to instill the values you're trying to reverse!) then that's not really 'helping people to grow' but just that - influencing their behavior patterns.
