I beg to differ. It isn't too late to pull back from the brink. Going for the nuclear option in the current world financial crisis could be considered suicidal.
I dare say there is an amount of brinkmanship from BA Management, but just 15% of pilots flying choice routes might enable BA to see out 72 days and then the firings would start. I wouldn't throw my job away without knowing the exact situation. I have heard of resignations from BALPA in recent days.
If it was me I would be monitoring the situation very very closely. I don't share your rose tinted view of workforce solidarity, I am more convinced by the frailty of human nature.
I still say good luck, be careful who you trust.
