Abstract
The use of extended workdays (regular shift lengths of 10 or 12 hours, while still maintaining a 40-hour workweek) in mining operations is attracting growing interest in the United States. While the popularity of extended workdays has been on the increase, there are some serious concens by management, workers, unions and various governmental policy makers that working 10- or 12-hour days may create an added risk of accidents and health problems. The manuscript represents a review of the literature related to the safety and performance issues of extended workdays. The objective of this manuscript is to describe all relevant research that could aid in decisions regarding the use and implementation of extended workdays. The studies examined in this review are divided into three sections: (1) laboratory studies; (2) field studies; and (3) accident analysis studies. In general, results are inconclusive. Studies have shown both positive and negative effects. It is concluded, therefore, that in industries such as mining, where accidents are a serious concern, special measures and evaluation in the use of extended workdays be considered.
