I warn you now, in 1989 airline pilots in Australia struck a plan to resign en-masse to get the airlines to the negotiating table. Airlines called their bluff and accepted the resignations and immediately made new contracts available to anyone who wanted them. DEC’s were offered, many foreign pilots took positions and that caused a few local pilots to jump on the band wagon. The airlines ripped up the previous contracts and weeded out those who they didn’t want back.... they did all of this with the support of the then Government. Be very careful, don’t rely on everyone doing the right thing, it will just take a few to sign the new contract and then people will pile on especially if they see external pilots taking jobs, and there is no shortage of them. Good luck.
