STUDY OF TEXAS EMPLOYEES REPORTS HIGHER NIGHT-TIME INJURY RATES
Kenneth D. Fortson, a Ph.D. candidate from Princeton University recently published study results showing that the "injury hazard is substantially higher late at night than during regular daytime work hours." Mr. Fortson's findings were presented in the Monthly Labor Review.
Night workers typically have longer work schedules verses the number of hours worked for daytime employees. Differences in the duration of work hours can have a sizable effect on nighttime injury rates. Fortson also reports, "There is little evidence that fatigue is the primary contributing factor for the late night spike in injury rates." And although younger, more inexperienced workers may be employed at night, "the injury pattern is not simply an artifact of a disproportionately young and inexperienced workforce working late a night."
Studies indicate that workers are not optimally alert during night shifts contributing to higher injury rates. "Biological patterns known as circadian rhythms are processes that generate diurnal variation in the body. This coupled with the empirical findings in this report provide strong evidence that workers are not optimally alert during late night shifts contributing to hazardous working conditions for them as well as their fellow employees."
