At the end of the day everyone does whats best for them and to hell with everyone else. It's human nature. As a wise A scaler told me, the only way to have a cohesive contract is to have no variables. Everyone is based in Hong Kong, no-one does W patterns, no one flys on G Days, no one does an "early" command getting F/O pay for the privilege. Everyone is on the same housing, no fixed or floating option.
