Arizona is a right to work state so I could be fired for anything. Company has a policy against firearms on property or anywhere they are conducting business. Even if they didn't have that policy it would be difficult for my since my job takes me into hospitals, courts, police departments, schools, post office and other prohibited areas on a regular basis.
I would if I could. Just I like having a job in this economy and in my little town the only shootings have been suicide, cop self-defense, and angry tweaker road rage.
Feel reasonably safe without and better that wherever I am my car is with me and I do carry in the car at work. The parking lot issue isn't mentioned in the personnel handbook.
