I used to deliver pizza PT for a nationally known company. I also carried a gun. I was given the choice of driving unarmed or termination. The essence of "concealed carry" is that you are not visibly armed, and you do not volunteer the information to your employer. If your employer does not know, then it does not become an issue
We had vehicle inspections on a regular basis. It was seen under the seat by a nosey asst. manager.....so, the choice was presented and I made the decision to be safe.
