State Constitutional 2A rights and "shall not be questioned" Or however you are quoting it applies to government upon the citizenry. A private business can make whatever rules it wants for it's employee's if it is not violating some kind of regulatory law (discrimination, OSHA, etc). So it's your choice if you want to carry, but you can expect to be fired if caught. Like others have said depending where it is, unless you can afford to lose the job, just leaver it secured in your vehicle. I even work somewhere at elevated risk (but still remote over all) for an armed intruder and I still along with most of the other employee's have our armory in the parking lot.
