Quite a while ago, I made the point - completely ignored by all - that existing cabin crew have the luxury of several years to adapt to Mixed Fleet and other changes. I can point to cases either inside and and outside BA where employees have suffered base, office or factory closures, have had to move home to get to their new place of work, were told by their union to take VR as nothing better was available, or even were dismissed at short notice.
And I might point out the bleeding obvious that it's better to face uncertainty inside your company than face it outside. It's almost incredible that people like MissM would be prepared to strike until BA goes bust.
