OK, I am new here and this thread is exactly what I was looking for.
Per my employee guide: "Employees are precluded from possessing dangerous weapons, including handguns, while on duty or in company facilities."
This is the only reference I can find. Also, there is no reference to 30.06 anywhere on the grounds or in the books.
I am not looking at it from CHL perspective (I do have my CHL). I just want to be able to keep my handgun secured in my vehicle so that I can attend a nearby shooting match after work. It looks like I got the answer, although it's not the one I want. Our parking is on the property, so I assume that would be included in "company facilities".
As an aside, due to the total lack of signage, I see nothing restricting other people (vendors, contractors, visitor) from CC'ing at our business.
Either there is a chance they will search your car or use dogs, or there isn't.
