Will industrial action work? Who knows?, but my guess is no, it won’t And worse still the JQ IR negotiating team, in all likelihood, believe this also. To presume that the QF&JQ managers have not war gamed and simulated the possibility of every permutation of industrial action is naive.
For those that cannot live with the status quo, I’d be getting in ahead of the wave and applying for a position with Tiger or Virgin where Ts&Cs are better and also overseas. Not so easy for those with significant seniority in which case I’d be looking overseas for a DEC position. There are jobs overseas for well qualified and experienced pilots.
