HiFlyer:
Where exactly is it going to be available...any access at hubs, etc.?
In all honesty I can understand BA's position not to make it web-based given the actions of some of the more militant BASSA members.
I perfectly understand some of the apprehension you must be feeling.
However, it doesn't necessarily have to be a negative. This could be BA's communication to non-cabin crew regarding a settlement, and why. It could simply be a message acknowledging the situation and thanking them for their continued support of BA.
Its a bit unsettling for Cabin Crew that this is taking place without any signal from Unite/BASSA. There are many reasons that BA may take decisive action (further threat of strike effecting bookings, etc.), but there are also other possibilities.
You are correct, a change of contract situation would be horrific from the CC's/BASSA's point of view, but its not as if the rest of BA or the public at large are going to be sympathetic. BA's hand is almost being forced in this issue.
Good luck and we can only hope for the best.
