12-hour shifts best kept to not more than 8 consecutive days, according to study

Workers scheduled for more than 8 consecutive 12-hour shifts operate under fatigue-induced impairment comparable to being drunk, according to a study of Australian miners by researchers at James Cook University (Queensland, Australia). The miners' schedule has them working 14 days in a row. Researcher Dr. Anthony Carter says that after 8 days of such work, worker's performance is similar to a person's with a blood alcohol level of .05.

The study's authors recommend limiting strings of 12-hour shifts to no more than 8 days.
