Mr Manager,
As for defining succesful, from this side of the fence there does not to appear to be much to be on offer. NATS at present - uncertainty over financial issues ( spare cash or not ) , uncertainty over jobs, unhappy atco workforce, unstable area control equipment etc.
Leaving to find further gainful employment elsewhere. Shouldn't be too long before the laughable manning projections for atco's are further put into dissarray by the odd one or two deciding that enough is enough. Shame really, bit of a disgrace that atco's and many others take great pride in doing , as you say, an exceptionally difficult job in a highly professional way that is applauded and envied worldwide - except in One KS.
Disillusion creeps further and further......
