I work in the office and rarely do I go into the plant.
1- Our employee handbook says nothing about carrying at work.
2- I have never been told we cannot carry at work.
3 - There is a sign on our gate that specifically states.. well, see for yourself

It specifically says "into the plant"
I work in the office building, and I can lock my desk, if I need to go the plant (but that would mean unconcealing to do so).
My HR Manager is an ex-cop, and he has said before, in casual conversation that "I (meaning he) always has a gun on him". This came up prior to my looking into and trying to get a CHL, and did not pry any more than that. But I am worried that if I go to him and ask, I will get the "no you can't" when as I read the sign, I can, as long as I do not go into the plant itself.
I do say there is a distinct difference from the plant to office as you are required to wear a hard hat, steel toes and safety glasses in the plant, but not in the office.
How do you all see this scenario playing out?
