Homicides accounted for 709 (12 percent) of the 6,026 fatal work-related injuries in 1998.
While many may assume that most work-related homicides are crimes of passion or anger, committed by disgruntled coworkers, spouses, or acquaintances, this is not the case. Of the 428 homicide cases in 1998 where the victim-perpetrator association could be identified, fully two-thirds involved robbery.
Coworkers and former coworkers accounted for 15 percent of identifiable cases of workplace homicide, acquaintances for 7 percent, and relatives for 4 percent. Together, these three categories accounted for barely a quarter of the total.
Data on workplace fatalities are from the BLS Safety and Health Statistics program.
