Employees with valid concealed weapons permits now have the right to bring their licensed firearms into company parking lots.  You can no longer ban these employees from transporting or storing their firearms or ammunition inside their privately-owned vehicles as long as (1) the firearm is locked in the trunk, glove box, or an enclosed compartment within the vehicle, (2) the firearm and ammunition remain in the vehicle when the employees are in their vehicles, and (3) the vehicles are parked in a permitted location. You can still prohibit employees from carrying weapons in company-owned buildings and vehicles.
