Mariner,
I personally think it is the sackings and suspensions and BA's requirement that the arrangements between the union and BA are modernised, that drives the reps on.
They are just using misinformation to the cabin crew as a way of getting them all on side. I am sure that the reps know that this deal is actually quite good. They are just totally embittered because some of their colleagues, in their eyes, have been unfairly and harshly treated plus the removal of staff travel seniority.
That's what drives this strike on.
