A question to those people who are considering a Yes vote in the ballot - What do you think is realistically going to happen in the event of a No vote?
It seems very unlikely that management and unions will accept that as a final decision and simply forget the entire matter until NATS may or may not face financial problems.
The probable outcome is another round of talks, during which the Union can go back and do it properly. If you think, as the Union and Management claim that this is the best deal possible, consider this - ask management for an extra £10 Xmas bonus this year in return for a guaranteed Yes vote, they'd bite our hands off.
Yes it's a stupid example, but the point is that this isn't the best deal possible, it's simply the best deal that our Union have manage to negotiate so far.
Send them back in there with a strong No vote in the ballot, the full backing of the membership and stop overtime (officially, by suspending the overtime agreement as per the mandate), see how long before Management magically come up with a better offer. If the original Union negotiators feel they can't go back, there are plenty of people I can think of who would have a go.
I'm not saying it will be vastly better than we have now, but this is a long term problem, we have nothing to gain by leaping at the first offer.
Think about it before committing yourselves to a 15 year deal, once you vote Yes, there's no way back.
