The first chipping away of the once mighty NATS pension has begun and will continue to be eroded at every chance from here on in.
The main reason people stayed for an entire career is no longer there.
Plenty of people are looking elsewhere already and I would expect quite a few to wander towards sunnier climes. Maybe take VR and then off to pastures new wouldnt be such a bad move.
Well done NATS management, you have potentially shot yourself in the foot there... better appoint new management roles to compensate and do it quickly as thats all you are good at !!!
