The company I work for does not post it but it is in the handbook that you are not allowed to carry or have a firearm in your vehicle on the premises. My boss that retired used to carry so I asked the owner of the company how he felt about it. He told me that with times like they are, he is cool with me carrying as long as it is concealed and no one else see's it. He also said that he feels good to know if anything happens someone else could respond. So, as soon as I get my HCP I will be carrying.
I guess since we are a small locally owned company I am cool with him saying ok. I am lucky to have a boss who understands. Also, he is a HUGE hunter. So, I am good.
