Results revealed that workers in the taxicab industry had the highest rate of work-related homicide (26.9 per 100000 workers). High rates were also discovered for workers providing public and private security and in a number of retail trade and service industries. For many high-risk industries, the risk was excessive for male workers only. Differences between rates for black and nonblack workers varied across industries and occupations. Findings indicated the need for immediate efforts to protect workers and long- term efforts to describe and study work-related homicide thoroughly and to evaluate interventions.
