Hand Solo,
Except for a late appearance by Overstress you are the single BA pilot trying to explain why this is bad for everyone involved in the long run. As another BA pilot I applaud your effort. It is extremely short-sighted to say 'I'm alright, Jack' because it merely opens up the way for BA to franchise out to lower and lower paying companies until someone gets the bright idea of making pilots work for free if they want to do the job so much. In the meantime the reduction in T and Cs doesn't do anything for the pax who pay the same for a ticket regardless of who is operating the flight.
I'm trying to be succinct because I think Hand has made a very rational argument so that's all from me.
