Some excellent responses. I totally agree with the fact that alcohol and drugs have no place in the work place, I do think that the fatigue issue is bigger than one can imagine. I am sure the management in any profit making organisation will always get the "experts" in and make sure the results lie in the side of profit. Not saying that mr pinkman would have erred on this side. I would also like to add that as a human I am also a complete expert in human fatigue. I like to sleep when its dark and be awake during the day, I also respond to food and water. Which as you may have noticed is somewhat lacking in some of the steel lockers we now work in.
As an aside why is it that in the states there are loads of drinking water fountains in the airports but here its just plastic bottles at rip off prices and more waste for the planet. mr green from angry.
