From an outsider who was gouged during the 1989 Australian punch-up, and has experienced a couple of management try ons in other companies since......
For whatever reason, managements worldwide appear to be simultaneously taking on pilots' unions. As Hawke said in our dispute, "Go out this time and it's WAR boys!" - and he was correct with the analogy. In your stoush there will be no Marquis of Queensberry rules, they (CX management) will fight hard, heavy, and dirty...and the "war chest" is bottomless - completely non-accountable money, because it's "for the long term survival of the company". There probably won't be anything new, management just aren't that clever, or imaginative.
You can bet your phones will be tapped, and there'll be the odd slimey "plant" who'll feed info. back in the hope that he can gain something for himself.
Be imaginative, and keep your groin protected!
But in the end, if there is no negotiated settlement between company and union, CX will probably go the same way as Ansett - a slow, lingering, withering death.
