If you have a CHL and a 30.06 sign or your employment agreement prevents you from carrying, there is a serious legal issue. Say there is an incident and you or a loved one is injured or God forbid killed. Those who have chosen to revoke your right to protect yourself ARE liable. I verified this with a police officer as well as a lawyer.
However, if you do carry at your job and something happens. Even if you save yourself and others, there is a good probability you will still be let go because you broke their employment agreement. If you chose to pursue, It would be a toss up with a Jury. Tough decision. I follow the rules whenever possible.
