OK, a bit of a background before the question. I work nights in a large facility here in reno. Our security is basically a glorrified secretary so if there is a problem they call us. I got a call at about 2:00am about a strange car in the parking lot. I get in my truck (I park next to the Boiler room) and drive out there. As I pull up to a car parked sideways in the parkinglot our supervisor is also walking up. When I shine my flashlight into the car to check it out, there is and AR-15 in the front seat. I take a second look and it is an Airsoft, but the supervisor kinda starts freaking out a bit. I explain to him that it is a BB gun and he settles down. He does insist that you can't have a weapon on the company property!
OK, now the question.
Since Nv. considers your car an extension of your home can an employer tell you you can't have a weapon in the car like that?? I have always been under the assumption that they can't say squat about it, just like it is legal to carry a loaded weapon in your car here.
