Tommy, I think we are pretty much in agreement in 'concepts', it's just where we see the terminology differently. From what many have been saying here, any reduction to part time, compulsory or other, with the resultant reduction in pay would be seen as a change in Ts&Cs. But I agree with you that it makes an enormous amount of sense to keep as many as possible in jobs. Unless there are contractual agreements for redundancy in the UK "... the maximum statutory redundancy pay you can get is £16,140", so not that expensive. Pilots should get together to avoid other pilots being 'thrown under that bus', as more and more pilots out of jobs will drag down any future Ts&Cs fast.
GKOC41, face masks are not worn on the flight deck. Joe is correct on that one. They are only worn as you are leaving so I don't think that closing the door can count as a 'critical point'!
