Stand-your-ground laws prohibit civil suits against armed self-defenders cleared in criminal court. The prohibition doesn’t cover their employers. As you might imagine, insurance companies won’t touch that one with a ten-foot-pole.
So, while independent businesses like jewelry stores and privately-owned Stop ‘N Rob convenience stores “allow” employees to tool up, the number of franchised businesses willing to take that risk is, basically, zero. But if Circle-K, Checkers, Pizza Hut, etc. employees could carry, should they do it openly or concealed?
Have you ever seen any business (other than a gun store) with open carry employees?
