Actually Undercover both you and sector8 are wrong.
At the conclusion of the CTUS pay negotiations the negotiating teams, including the ATCO one, agreed to recommend to their own BEC`s that the deal on offer was the best that could be achieved by negotiation. No more, no less.
The ATCO BEC, after discussions, decided to recomend rejection and make it perfectly clear that industrial action would be a distinct possibility if the members voted no.
It is the ATCO membership who rejected the deal very conclusively.
