Yorik, I don't see the Jetstar people as scabs. They were not involved in an industrial dispute and AIPA gave them the cold shoulder when it counted.
It could have been much different if AIPA took a more pro-active stance but they put their head in the sand. Now they are trying to cobble together a bit of a broken down face saver that will appeal to no one.
That the Jetstar agreement may result bad things appearing down the trail look no further than AIPA. No scope clause guys....dumb.. dumb.. dumb.
