How does shiftwork influence variability in work performance there is extensive evidence that relative to day and afternoon shiftworkers, night shiftworkers tend to work at a reduced level of effectiveness, as measured both by various indices of job performance and by standard behavioral and physiological function tests. Between-shift variability in work performance thus may be explained as a consequence of circadian dissonance, in which night shiftworkers are asked to fulfill their job responsibilities in the face of depressed behavioral and physiological functioning. Another dimension of work performance variability concerns the consistency or reliability with which a shiftworker is able to perform his or her work during a shift. Possible shift-specific effects on such within-shift variability have not been closely examined. Clearly, a comprehensive understanding of the interaction between work performance variability and the work shift must address both between- and within-shift manifestations of variability. This U.S. Bureau of Mines report presents findings from the first phase of a study designed to compare the performance of mineworkers on rotating 8- hour shifts to that on rotating 12-hour shifts. Only findings from 8-hour shifts are given.
