The level of 'support' is irrelevant, the strike mandate is irrelevant. Bassa have failed to achieve anything apart to a return to the status quo after the initial imposition. Unite won't call more action and they will advise BASSA against it. If BASSA and their lunatic secretary go ahead then it will have no impact whatsoever!
Delude yourselves as much as you like, BASSA is a toothless dog now so negotiation is the only way forward if BASSA want to salvage anything from this.
