Lack of trust?
The thing is Litebulbs is that if the 5,000-odd who voted yes (and perhaps some who couldn't be bothered with having a say in their own futures) dont believe or trust anything their employer says then no agreement BA propose would ever be satisfactory. Even reinstatement of the sacked, return of ST, and allowing CSD's to put their feet up again on their current agreement will not be satisfactory if they don't trust BA not to change things in future.
If this lack of trust is genuine at CC level rather than just posturing by the union, then the only solution is for the CC concerned to go and find an employer elsewhere that they do trust. Or be booted out (with assistance from BASSA if they do go ahead with what BA will say is an illegal strike) if they won't take the initiative and leave
Tough maybe when they've got a mortgage to pay, but what is the alternative?
