Maybe through proper negotiations. BASSA is as guilty as BA. I don't think it's easy to negotiate with either side because they are simply too far strong-minded. BA has one agenda. BASSA has a completely different one.
Everyone is entitled to their own opinion. If crew have voted against a strike or are not part of a union it would make perfect sense for if they don't strike. We had an almost 80% turnout for a strike in our latest ballot and I'm very disappointed with all those who voted for a strike but didn't go through with it for whatever reason. There were crew who came down to Bedfont and showed their "genuine" support and then headed off to work. If you don't intend to strike, don't vote for it. It's not rocket science.
It's a saddening behavior. It's the same with all strikebreakers from behind the flight deck door, Waterside, other departments within BA and ex-temporary cabin crew who have returned to the company.
