In 2009, the most recent year for which data is available, approximately 81% of workplace homicides were committed with a firearm.1

While workplace homicides have decreased steadily over time, the rate of shootings committed by co-workers or former co-workers has remained steady, with an average of 45 homicides by shooting committed by a co-worker or former co-worker per year between 1992 and 2006.2

A 2005 study found that workplaces where guns were specifically permitted were five to seven times more likely to be the site of a worker homicide relative to those where all weapons were prohibited.3
