The 1.1 million cases of lost-worktime injuries and illnesses reported in 2002 that included data on the time of the incident were fairly evenly distributed from Monday through Friday.
Among high incident occupations, truck drivers (includes heavy, tractor-trailer, and light or delivery truck drivers), janitors and cleaners, and carpenters had a greater proportion of injuries and illnesses on Mondays.
In contrast, cooks and sales workers had a greater proportion of their injuries and illnesses on Thursdays and Fridays.
These data are from the BLS Injuries, Illnesses, and Fatalities program. Additional information is available from "Time of Lost-Workday Injuries and Illnesses, 2002: First Results Announced by BLS," (PDF) news release USDL 04-2407.
