Excellent points there CCC. I've had to work similar shift patterns and then had days off where my body just cannot get realigned to "normal" time. What happens next? Of course it all happens over and over again, with minor variations in the detail. The key difference being I'm not responsible for hundreds of lives.
The news report mentions quite early on: "Trainee doctors should no longer be working more than 58 hours a week under European regulations." The authorities apparently consider a 50% loading versus the normal working week quite acceptable. We should all bear in mind this is an "improvement" for them...
