The way I understand it, the BMI pilots have a choice. Either sign the compromise agreement and integrate voluntarily or choose to stay in the "bubble". It remains to be seen exactly what percentage of people choose those options but it was inevitable that some people would choose to remain seperate. I suspect they will be in the minority and will feel increasingly marginalised. Eventually this may well result in discussions with management along the lines of, "Do you really feel BA is for you given your deliberate choice to remain seperate?" The option to integrate exists and that is what the latest negotiations were about - providing that option.
This means that BA pilots who gave up 2 days leave a year and 10% productivity changes in order to save their (BMI pilots) jobs
Thats a pretty bad misrepresentation of a completely seperate issue. If we're honest, BA pilots voted to give up leave/provide productivity increases to avoid the creation of a "BA express" operation at Heathrow which would have directly impacted their own job security/career progression. In that sense it was an entirely selfish dilemma and had little to do with what was best or worst for bmi pilots (in reality this was probably a better outcome for them as at least they are now afforded TUPE protection).
Finally,there was no suggestion that a no vote would have resulted in bmi job loses, just a stand-alone operation within IAG.
