I agree that the triple whammy is about to happen. I heard figures of +400 guys reaching 65 and 55 by 2018 (10 years since Cos 08). Add to that a few new joiners and it will quickly become unmanageable.
I agree about a new contract, but by judging history, Cx will try and give nothing or take stuff away for exchange to 65 and bases...both of which they need.
...have you heard the term ...have your cake and eat it!
