According to a federal judge, companies can fire an employee for having a gun at work, even if that employee uses it to stop a robbery at the store.

This decision spells bad news for Walgreens pharmacist Jeremy Hoven who used his gun to stop an attempted armed robbery at a Benton Township Walgreens in May of 2011.

When two masked, armed men entered the Walgreens where 36-year-old Hoven worked, Hoven took action. Seeing that they pointed guns at another Walgreens employee, Hoven shot at one of the men.

Eight days later he was fired for breaking the company’s policy about having guns at work. Hoven sued Walgreens for firing him. He says that he had a permit to carry a concealed weapon, and that he only fired the gun in self-defense and defense of others when he stopped the robbery.

According to WSJM, this week U.S. District Judge Janet Neff ruled that even if it was self-defense Michigan’s Concealed Pistol Licensing Act allows companies like Walgreens to establish their own policy on whether employees can be armed at work.
