I ignore my company gun policy also. I leave it in my car though. If I'm not mistaken, .ga law protects your right to carry to work. Not inside the business, but in your car.
You are correct in that, but it really is a sticky situation to find yourself in. I believe the law restricts your employer's right to search your car, or have it searched by police, but I still think you can be fired for having it against company policy.
