People will always join BA. What you do not realise (already being on the inside) is that you are well rewarded by industry standards.
There are many many airlines who work damn close to your 850 hours a year and get nowhere near the pay you lot do. Not to mention the healthcare, travel perks etc etc.
There will never be a shortage of applicants to BA. Admittedly, you may not attract people from First Choice, Thomas Cook, Monarch etc etc any more, but you will ALWAYS attract people from other smaller airlines.
And what's more, these people don't care about your final salary pensions.
Sad but true.
In the meantime, I wish you well in your negotiations with management.
