The later am afraid Pat, the dispute was never about pay. Basic pay is less than one third of the income yet BA dwell on it as though being generous. What is important is allowances when you work with some trips being far more lucrative than others.
Behind the scenes BA have been moving over the lucrative routes to the mixed fleet penalising the legacy crew further. Publicising the 3% one hand in base pay whilst silence on allowances being reduced by 3-4 times is typical of a BA PR game.
Also look in detail – the agreements BA have broken stay broken. Why do BA believe ACAS cannot be trusted to provide fair decisions when an impasse is reached? BA has loaded the deck by being able to reject arbitors (I assume those that don’t call it in their favour) and even if they get it wrong they need not be bound by the decision of ACAS.
They also want a no strike agreement so the leadership can ride rough shod over whatever it sees fit without risk of IA.
It was never going to be acceptable that is why 83% voted for industrial action.
