A proper system requires a reasonal committment from both the employer and the employee.
So Bushy..............try telling that to a REX F/O living in Sydney on $40,000 odd dollars after he's spent huge amounts of money to get there in the first place.
It's time for Airlines to actually pay a decent fair wage and maybe a bit more for the Pilot's to WANT TO STAY.
Then the Employee might be happy to give a REASONABLE COMMITTMENT.
It's a two way street.
Simple really.
