I know they do - I was however hoping Pelton Level would reply.
Lots of ATCOs do extra sectors for no money - although it doesn't include extra working hours as that is constrained by law, it does mean more bookwork, more annual exams, less early go's (I know, a perk not a right), less comfortable night shifts... no extra money, but without it, the centres would not run, at least not without a huge increase in overhead.
It is easier to recognise the office bods who (regularly) work over their contracted hours to help the company, as extra sectors etc are contained within the normal working hours. I think nowadays, NATS sees people doing extra work for the company for no reward as a norm and
expects it from people - exploiting, to a degree, the pride people have in doing their job.
However, the Belgians have, it seems, played a very clever card. I hope they resolve the issues to their satisfaction
