I speak as an outsider looking in, but it seems to me that a lot of what is going on between CX and the AOA is pretty well based on personal vendettas, rather that the cold facts. The current climate isn't a great one for anyone, pilots or management, so why can't both sides put their differences aside for long enough to sit down and talk.
As a recently redundant pilot myself, I would have no hesitation in taking a job with CX; when it is a choice between being banned from a union, and feeding my family, there is no choice.
Grow up guys.
