Hector, BASSA has lost. How can anyone say otherwise. By definition if they haven't won they must have lost.
BASSA expected BA to cave in last year as had happened so many times in the past. Now 18 months later, membership has fallen dramatically, actual 'do not go to work' support of the strike action was ~50%* or less, ST has been lost, the only offer available now is materially worse than those available only a few months ago and even in his postings DH talks about collapse, being beaten, weakened etc.
If that is not failure, I'd hate to see what is. BASSA could have come out of this situation a WHOLE lot better. It's BASSA's fault how badly they managed their strategy. Now it's a case of when they collapse rather than if, they've used the only tactic they have and it blew up in their face. I'd even go as far as starting a conspiracy theory that DH has been paid to weaken BASSA from the inside because in his tenure as leader he has done more to weaken that union's influence than the last 5 BA CEOs combined!
* Approx 14,000 cc. Taking BASSA's figure of 7,000 strikers = 50%. Taking BA's figure of 5,000 = 36%.
