I am thinking she is just going to ask you not to open carry while on company property. she can't say a whole lot about CCW as long as she never sees it. customers probably know you and want to know why you open carry, which could cause problems for the company...and for me too since I own stock!
I would imagine she will just talk with you about it. She wouldn't want to get in a big legal dispute over your right to carry etc. etc. but it also depends on what your company handbook says and the rules of working there. if anything is in there (and probably is) that says you can't have a firearm on company property or whatever BS they feed you, that might be grounds for termination.
