ABSTRACT
Performance of tasks depends upon muscular contractions, which in turn require expenditure of metabolic energy. The metabolic energy requirements are substantial in the event the task being performed is physical and highly repetitive. Rest allowances are given to avoid these detrimental effects. During rest periods, workers recover from the fatigue that is generated as a result of producing work. Fatigue or rest allowances are given so that workers may recover from physiological and psychological effects of work. Rest allowances can be added to the working time either as a percentage of work time or as a percentage of shift time. This chapter discusses a procedure that provides rest allowances as a percentage of shift time. It shows program output for an actual case as well as the differences in rest allowance determination when the aerobic capacity is known and when it is not known.
