Alan Joyce made the tough choice here, he took the hard option and is finding a long term solution to solve Qantas' problems.
He's going to get this sorted out, and Joyce will not have Qantas flying until an acceptable solution is found.
Good on Alan Joyce I say, he's got some serious guts to ground an airline. He's earning ever cent of his pay cheque right now.
Joyce didn't make a tough choice - he made a childish one. What did he achieve? He got the government involved.
Put anyone else in the job, and all they would have to do to get the government involved is to ring the PM and tell her "Get involved, or the airline gets shut down tomorrow". Then the PM gets involved etc etc... they can go through all that without shutting down the airline.
If that didn't work, then by all means, take the scorched earth approach and burn the airlines, but give people warning at least.
The bottom line is that Joyce could've got the government involved in this WITHOUT shutting down the airline with no notice and stuffing up the lives of hundreds of thousands of people and costing the country millions as well.
