They want to steal our pension...
No they don't! But they do want to change the pension
for new recruits - quite a different thing, and rapidly becoming the UK industry 'norm'
(realistically, something from which NATS cannot remain immune).
But, as for an RPI + 1% pay award from January 2009, on the basis that traffic is still increasing (at least according to the Company's own Corporate Communications Department and its frequent posts on the NATS intranet...) then arguably, controllers' productivity has also increased and therefore, the pay rise should reflect this achievement.
The fact that an increasing number of aeroplanes might be flying around with less than break-even load factors is irrelevant to the ATC activity and effort required to safely control and separate these aircraft.
