Perhaps if enough of us wrote to the union we could get a extraordinary general meeting to debate the issue of AAVA's with a view to the union organising a vote to stop doing them and then have something to go to the "Working Together" table with an talk to the Red Barron about when the NATS attributable delays go through the roof!!
The thing with that is that you wouldn't necessarily get everyone to agree to it. I have sympathy with the plight of the guys at MACC, it seems, working almost entirely on AAVA's. But spare a thought for the smaller units.....
I think it'd be fair to say that they're pretty well subscribed now, my unit is. Therefore, the AAVA's that do get offered tend to be snapped up happily, as they don't come around too often, and the (small) amount of extra money is gratefully recieved. I think you'd be hard pushed to get everyone to agree to a ban......
