New and changed rules are in affect for air traffic controllers as there have been recent incidents where controllers are falling asleep on the job.
According to the Associated Press, the new rules will be applying to truck drivers, firefighters and other jobs where there is extensive need of changing sleep habits and working night shifts.
According to CNN.com, the new rules came about when there was a seventh incident when an air traffic controller was suspended after being found sleeping on the job.
"Controllers will now have a minimum of nine hours off between shifts, instead of the current eight-hour minimum." Most controllers are given shifts of a week of midnight flights and then a week of morning flights following right after. "Controllers can no longer be put on an unscheduled midnight shift following a day off."
