Noodles - As a relatively recent J* F/O joiner, I was on an AWA and yes, I effectively voted to dump it and move to an EBA. Many in exactly the same position. This took precedence over the initial salary issues and the 5 year term of the EBA.
At least now, the vast majority are now on the one agreement. (I assume here that most would have elected to move from the AWA's). All we need to do now is sort out the representation issues to our advantage. It's all very confusing.
