I agree entirely that someone is going to have to swallow their ego. Sadly, the two sides of this dispute also happen to be two of the strongest egos any of us will ever have encountered.
However, I don't agree that Walsh should be the one to give in. He may be the senior party, but he's also the strongest and enjoying the most support. He has the support of his pilots, ground staff, engineers, office workers... Bassa appears to be able to boast the support of the unwashed hoodlums of the Socialist Worker Party.
Isn't that normally the person who emerges the victor?
I find it incredibly difficult to talk so negatively about Bassa, for I maintain enormous respect for the reps and for the work they do to secure favourable terms and conditions for us, the cabin crew. But this time around it's all gone too far and I wish they could see that.
