Ted, I think you can keep hoping, but don't hold your breath!!
I really do suspect that after the strike dates have been announced, BA will be forced to issue a 90 day SOSR notice, introduce "draconian" (or industry outside BA) Cabin Crew contracts, and invite any strikers who want to, to return on the new terms........or their old ones for 90 days.
If they don't change the crew now, the problem will keep resurfacing.
