What happens in the medical profession is, in the first instance, their affair & for them to sort out. And, for the rest of us, to avoid getting admitted to hospital!
What happens in ATC is the affair of Controllers & ATSAS.
If Spanish ATCOS are being told that they can only have 2 days off in 6, & 1 of those being a rest day after a night duty, then that, in my book, is TOTALLY unacceptable - for reasons which I do not need to explain here.
