A happy worker is a productive worker. The company has just once again turned toward bona-fide profitability in a more and more competitive market--partially because of efficiency gains helped along by the people you want to keep happy. Happy workers go the extra mile sometimes when they don't have to. Happy workers sometimes answer the phone during time of crisis when they aren't required to. Happy workers sometimes go to work when strictly speaking they don't have to. Building animosity always hurts everyone and will ALWAYS hurt the bottom line in time. ALWAYS. And it's usually the decision makers who wind up unemployed when the bankrollers see the bottom line headed south.
Maybe someone is forgetting they need pilots to drive the shiny aluminum tubes, and that there's a bit of a shortfall given the greater quantity of nice shiny aluminum tubes on the way. Or that some of their staff still are on the books at their previous airline. Or that there's not a limitless supply of pilots to drive shiny aluminum tubes around when folks are unhappy at where they are.
I guess my suggestion would be to keep the place a happy place
-- but it seems things are going in the other direction.
