Good on you BA Cabin crew.
Im with you all the way!
Good luck, and good on you for having the balls to do it.
I suspect an alc-fuelled wind-up; but here's another message for the brave lads and lasses. Who in Unite's headquarters will join you in the dole queue, when BA downsizes or goes out of business as a direct consequence of your suicide strike? Why not ask them about that. And about why they've manipulated you into a strike.
I'll wave cheerily to your pickets on the way in to LHR, (twice over the strike period, rebooked as soon as a risk of disruption loomed) but it's a "goodbye for ever" wave. If the tactic was to get passengers mad enough to force the management's hand, it's gone spectacularly wrong. They are not going to force anyone's hand, they are simply going elsewhere, and they will never come back.
Calling it all off now won't make any difference. Nor will any decision about legality. The damage is done. You might as well take the 12 days off unpaid while they write out the P45s.
