Well, if it goes like it did here in the States, if the first few groups don't draw the line and say NO to concessions and loss of pension, then forget about it. The horse will be out of the barn and now management will be talking about needing to "remain competitive" with the newly castrated pilot groups at the first airlines that give up pay and pensions. Who knows what would have happened at Delta and Northwest if USAir and United had gone on strike (and probably out of business)?
The hard part is to be the ones to take the bullet for the rest of the industry. Who wants to be the one to lose their job (if it came to it) to save the rest of us?
