You bet BA have a plan following the expected YES vote:-
Option 1 (BASSAs preferred response from BA)
BA go to the courts to get an injunction against any strike being implimented - this they could easily achieve given the tenuous lack of reason for a strike ballot in the first place.
Result - BA win because the new crew compliments are in and the savings are made. BASSA also win because they could claim thier hands were tied by the courts and it's the big bad company preventing their membership from exercising their right to take industrial action and how the Union has the moral high ground etc.
Option 2 (A BASSA nightmare)
BA don't try to fight in the courts at all and do nothing thereby calling the unions bluff. The union will be forced to announce strike dates which will be broken in the first 24 hours once a few crew are sacked. The union loses all credability. BASSA falls apart and BA get to impliment even more changes early in the new year following disappointing quarterly results etc
- New fleet implimented early along with Operational Recovery Proceedure (the replacement for the disruption agreement).
Option 3 (BASSAs worst nightmare)
BA yield to cabin crew pressure and announce the recent impostion of crewing levels is cancelled / rescinded. Crew joy for 24 hours until the 90 day notice to terminate all CC contracts under SOSR rules hit the doormats and that existing crew are invited to accept new (New Fleet) contracts or please return their uniform etc.
My bet is option 2 because BA win massivley with little disruption / cost.
BASSA would hate options 2 or 3 but option 3 is the worst for the union reps personally because it affects all crew not just the ones who are sacked on day 1 of the strike as you can bet none of the reps will be rostered to work that day.
