Yeah, okay? And? What are you trying to say. That Apple has 3+ years retention? 5? 1.5? What are you saying? Apple's employee turnover is very high, no matter what data you look into. Even 2-3 years is a lot less than ideal. People used to make 20-30 years long carriers at certain companies, and a burnt out employee who silent-quits the last 2 years of employment indicates what? It indicates Apple is a bad employer. Working for Apple is hell and you're forced to pretend you enjoy it, otherwise you're either pushed out or fired on a PIP. Even with a big, big, huge blind eye to the stats we do have, even 2 year rate is very little for a company for which "everyone wants to work".
I think a large chunk of folks tolerate working at Apple just to get it on their résumé.
