And at the top of everything I think that management of ANSP work properly( from their point of view) because they increased productivity without infringed safety.
Sure, they work properly.
They certainly have been working properly when they "magically" changed the staffing numbers at Munich from "120 too many" to "120 too few" within a few weeks...
Oh, and safety IS infringed, and the numbers show it. Just because planes don't crash doesn't mean everything is safe.
