Another problem is rotating shifts. When I was in the military, we had rotating shifts for a while. But our rotations were monthly; some people had a short turnaround and some didn't, but when you did, it was only once a month. These controllers are changing shifts far more frequently. That should stop.
Also, adding one hour to their break probably wouldn't make much of a difference. It's like when we went from 8 hour breaks to 10; adding two hours was what was meaningful. It would allow them to have a full 8 hours sleep in addition to their commute.
Rotating shifts if deadly. I worked them in the military and at the Agency for years. 6 days on, 2 off, change shifts. Falling asleep at work was common.
Sitting in a darked out room, no windows, starting at a screen, is a plan for tired.
Study after study was done, by places like Johns Hopkins when I was in. All said the same exact thing. NO rotating shifts and a nap period built in.
The British and Japanese had nap periods built into their shifts. Their error rates on mids were far lower than ours. When the Brits worked at a US site, where I worked with them, they worked our shifts and had the same error rates as we did.
I understand that LaHood has been informed of all of this research and in normal government fashion, ignoring it. He just says, no one is sleeping on my watch. What a PUTZ!
