Career FI - Does the school care? - in short no. Perhaps when the airlines are hiring and they are they are loosing a few instructors to them they may care a teeny weensy bit (or pretend to!), but when the situation returns to normal it is back business as usual.
Ex Airline and RAF jocks in the main couldn't be bothered with it much - particularly if they have to work for the abysmal employers we do.
Ex airline chappies are getting good jobs (and pay) doing type rating training on simulators so why would they bother with prancing about the sky in all weathers and week-ends for a bag of KP's finest in some beat out ancient C150?
