The gun laws in Ohio have expanded the rights of gun owners to carry weapons in the state. This includes allowing gun owners to carry weapons at the workplace. People with valid concealed – handgun licenses may now bring their firearms onto employers’ parking lots (subject to certain conditions), even though this may have previously been banned by employers. Don’t worry, the legislation provides Ohio businesses immunity from civil action for injuries, death, or other damages related to their gun policies, https://hr.osu.edu/public/documents/policy/policy705.pdf.
