Indiana soon could join at least 11 other states and allow residents to bring their guns to work, as long as they are stored out of sight in their cars. But a shooting in Portage, Ind., last week — in which a state worker frustrated over a poor performance review retrieved a gun from his car and fired at coworkers — is causing opponents to ramp up their pressure on Governor Mitch Daniels to veto the bill.

"This is further evidence that guns and the workplace simply don't mix," the president of the Indiana Chamber of Commerce told the Evansville Courier and Press . "The last thing our state should do is validate the opportunity for a disgruntled employee to get a gun from his or her vehicle and threaten the lives of innocent co-workers and bystanders."

On Friday (March 5), a 60-year-old employee at the Indiana Department of Workforce Development became upset about his job review, retrieved a shotgun from his car, returned to the office, and fired two shots at coworkers, The Associated Press reported . No one was injured.

The Courier and Press noted that the incident happened a day after the Indiana General Assembly sent Daniels the so-called "guns at work" bill, which would prevent companies from banning guns on their property as long as the guns are stored out of sight in employees' cars on the company parking lot. Daniels has not decided whether to sign or veto the measure.

According to the Brady Campaign to Prevent Gun Violence , 11 states have similar legislation: Alaska, Florida, Georgia, Idaho, Kentucky, Louisiana, Minnesota, Mississippi, Montana, Oklahoma and Utah.
