IMHO NATS’s Management have badly overplayed their hand. Offering less than half the rate of inflation after paying out millions in Management bonuses and tens of millions in dividends was comical and if it results in industrial action I expect some of them to be quietly replaced.
As Paul Barron proved with his Pension reforms it takes a lot to get to get ATCOs to seriously consider industrial action, it's taken the current management less than a year.
