FoxyTotty,
Interesting examples.
Only having a 2 hour nap in the time between that early shift and starting a night shift shows that the controller operated while unfit.
That was the controller's decision and unless you want the IAA to go home and tuck you up in bed then ATCO's have to take responsibility for either;
Ensuring that the obtain suficient sleep so as to start shif suficiently rested.
or
Don't start shift.
It is a safety issue.
Since the IAA have had people working and early, then short rest followed by a night for decades, it is very hard to turn round now and say that it is dangerous. Furthermore, when asked the staff said that they preferred to have a short rest in the middle provided they got more time off at the end.
Having 9 hours off and only sleeping 4 due to commuting and personal activities. - Living too far away from work?
NATS had the posibility of such problems - people travelling long distances home after night shifts. These people had moved in advance of the Swanwick opening. The answer - Hotel available if you want it. Simple answer. Put the onus straight back n the ATCO to turn up fully rested and not to risk motorway driving while fatigued.
I must admit that 6 on and 3 off is one of the better systems I have seen - with most of the night shift moving to various day shifts to bolster the day staff requirements. Much study into different systems never really came up with much better in terms of numbers and both management and staff satisfaction.
