BASSA will not be able to put up any meaningful resistance to this as it has been proven quite convincingly that only a very small percentage of the work force support them.
Don't think its quite so simple GW.
BASSA's missives to date all carry the same story, namely the strikes have cost BA millions, CC crossing picket lines only coz they're being bullied, its only a matter of time before WW caves in or is booted out by the board, ST will be reinstated etc etc
Human nature tends to give greater credence to "information" which agrees with and/or supports one's point of view. Conversly there would be a natural distrust of "information" supporting any contrary view.
I therefore expect many BASSA reps, supporters etc actually believe their own propaganda. The "20 jets at Cardiff" story is a good case in point -surely nobody in their right mind would attempt to peddle that story in an attempt to garner support when it was so easily disprovable. I suspect that rumour probably started with 1 BASSA member saying that's what BA would probably do and a couple of Chinese whispers later it was taken as "fact" and triumphantly announced to the media.
It is possible therefore that BASSA truly believe that the ball is firmly in WW's court and its up to him to make the next move. If so, they'll likely have a long wait....
