Yes people are leaving, yes they are trying to hire alot of people, yes they are talking about hiring straight to the 330, ANAC did intervene and there are about 60 widebody captains who are currently not flying because they didn't pass the English test. Only a few got downgraded to the a320 fleet but that was during the Barioni Era.
Switching to theses other airlines make sense when you have the time for command but you are number 900 on the list and you can go somewhere else and upgrade faster. Oh and yes I still work there.
