I recently went to a local motor sport event and there was 5 other fellow NATS/Aberdeen retirees there including an ex GM.Never seen such a happy bunch.
NATS and the Unions over the last 20 plus years have stripped away at staff numbers,Pension changing to DC,Increased BS generally,and pay regrading in the downwards direction at the lower band units.Also plugging the shortfall with AVAAs which is a sticking plaster on a gunshot wound.
Good luck NATS in recruiting the next generation of skilled controllers that have propped up the fading empire.
