Your "secret" SUB package seems logical but it really makes no value. If one needs a SUB of decent size ( L level gets 3 months minimum I heard and max is 50 weeks (not 52) which requires 25+ years) one has to be a senior position or long term employee
A long term employee until he/she gets the SUB is actually a quiet quitter. They are disillusioned (majority) and are hanging on to get picked (may be in their late 50s or early 60s)
Anyone who gets 26 weeks or above (10+ years service) are the ones who are in their late 40s or 50s and need their jobs. But mostly they are not quiet quitters and are trying to juggle and manage or talented enough to leave
Anyone less than 20 weeks - a few years of BNY - and they are not here for the SUB.
SUB is not the reason. And those who are waiting for the SUB (on the verge of retirement) have quiet quit (as I said earlier). So they are in fact vacationing with salary and benefits.
