On the morning of Aug. 24, Jeffrey Johnson returned to his former place of work, Hazan Import Corp., and waited on the street outside the building. Johnson, who was wearing a suit and carrying a briefcase, blended into the crowd of people on the street who were rushing to work that morning. As one of Hazan Import's executives, Stephen Ercolino, approached the building, Johnson drew a pistol from his bag and gunned Ercolino down with no warning, making Ercolino a victim of workplace violence. Media reports suggest that Johnson and Ercolino had been involved in several confrontations, at least one of which became physical, and that Johnson held Ercolino responsible for his being laid off. Each of the men had also reportedly filed police reports claiming the other had threatened him.
Violence in the workplace is a serious security problem in the United States and elsewhere, although it is not nearly as widespread as the media coverage suggests. On average, there are around 500 workplace homicides per year in the United States, according to the Bureau of Labor Statistics. In 2010, the latest year for which statistics are available, there were 518 workplace homicides, and only 12 percent were conducted by a co-worker or former co-worker. This means that while workplace violence incidents tend to get a lot of media attention -- even more so when an incident occurs near the Empire State Building, like the Johnson incident -- they are not common.
Still, while not all that common, incidents of workplace violence are serious. They are also, in most cases, preventable.
Threats or other indicators, like Johnson's previous confrontations with Ercolino, almost always precede a workplace homicide involving a co-worker. In workplace violence cases, it is very unusual for a person to just snap and go on a shooting rampage. Almost every case of workplace violence is planned, and the perpetrator intentionally targets a specific individual -- usually a supervisor, human resources manager or co-worker -- whom he believes is responsible for his plight. (We say "he" here because while women are sometimes involved in workplace violence, such incidents are predominately conducted by men.)
