There is no way to stop the race to the bottom , the company always wins and always has. Remember when the Qantas pilots said don,t join Jetstar on such poor conditions , I wonder where all the people are that took this advice , probably not in Aviation , but more than likely in JQ or VA.
the only floor in this is the pilot award for now , but even this will be challenged.
457 visas would open the floodgates, never will be more than temporary shortages in Australian Airlines.
