Phillip,
He doesn't need a CHL to have a gun in his home to protect from intruders.
Having said that, I do see the value of a CHL. (Obviously, as I have mine and value it.)
I, too, have to walk a thin line while at work. Although many of my colleagues know that I am pro Second Amendment, and some know that I like to shoot, they do NOT know that I keep a gun in my car while on campus, as is permitted by law.
I suspect that if anyone ever found out, the powers that be would ask me not to have it in my vehicle. This would count as verbal notice, so I just don't say anything.
In my case, they probably couldn't fire me. I don't recall signing anything. (If I did so years ago and don't remember, that's another story.) I'm union, and the representation is excellent. Unless I signed something, they have no grounds for termination.

OP, did you sign anything, thus acknowledging that you have been told not to bring a weapon on site? If so, I see your concern.
If you didn't, I recommend installing some type of safe in the trunk of your car or behind the seat of your truck. Keep weapon there while on company property. Unless they do random searches, no one will know unless you tell them.

The thing about having a CHL is that you never know where you'll need a gun. Susanna Gratia Hupp didn't suspect she would need one in Luby's one day. Luby's hasn't traditionally been the hang-out for the criminally motivated. Statistics were not on the side of her and her family one day, and she now wishes she had her gun with her.
