What BA are busting, is BASSA's STYLE of unionism. ie resistant to the very smallest of change, objecting to the tiniest thing (hot towels in WT+?), agressive, misrepresenting company offers by spreading completely inaccurate rumours about them, not turning up for meetings, refusing to negociate (unless it's on their proposal, on show of hands at a union meeting), making offers worth less than a third they claim (either laughably incompetent, or criminally dishonest) and employing the most purile childish rhetoric in their communications.
If BA have been trying dirty tricks, it's because they have to play hardball with a union that they know will spin things shamelessly to win support for their real aim, giving Walsh a right royal kicking. (Oh, and it seems now, sticking one up for the British worker in solidarity with the SWP).
All other areas of the airline, including other Unite branches traditionally pretty anti BA managed to get a deal with BA without being "busted".
The best thing you can do to protect your terms and conditions and prevent what BASSA claim will happen, is settle. Fast. Then rebuild a decent union, with which the company can work by having a complete clearout of the current BASSA and Amicus leadership.
I say this as a fellow cabin crew member and former union member.
