What is CX doing?

1) Can they even talk to Union leaders first so at least they can tell the public that they tried to negotiate in good faith?

2) Can they wait till off-season to announce this kind of moves to minimize possible strike impact?

3) I'm not in the airline industry so I do not know if NOT allowing cabin crews to swap will actually save money and how much, but from an outsider's perspective if the cabin crews can work out the schedules to swap I don't really see what's the big deal. Anyone with know-hows care to enlighten us?

Thanks
