There have been numerous threads concerning carry at work and guns in private vehicles on company property. I've researched a number of human resources web sites and found that the biggest (and pretty much only) reason given for forbidding weapons is liability to the company should the unthinkable happen. It has been suggested by some that the correct approach is not to force employers to allow carry or storage in private vehicles, but to eliminate that liability. I was reviewing the carry laws in -- of all places -- Ohio, and came across this law:

OHIO REVISED CODE 2923.126

(C)(1) Nothing in this section shall negate or restrict a rule, policy, or practice of a private employer that is not a private college, university, or other institution of higher education concerning or prohibiting the presence of firearms on the private employer’s premises or property, including motor vehicles owned by the private employer. Nothing in this section shall require a private employer of that nature to adopt a rule, policy, or practice concerning or prohibiting the presence of firearms on the private employer’s premises or property, including motor vehicles owned by the private employer.

(2)(a) A private employer shall be immune from liability in a civil action for any injury, death, or loss to person or property that allegedly was caused by or related to a licensee bringing a handgun onto the premises or property of the private employer, including motor vehicles owned by the private employer, unless the private employer acted with malicious purpose. A private employer is immune from liability in a civil action for any injury, death, or loss to person or property that allegedly was caused by or related to the private employer’s decision to permit a licensee to bring, or prohibit a licensee from bringing, a handgun onto the premises or property of the private employer. As used in this division, “private employer” includes a private college, university, or other institution of higher education.
