ConditionThree is absolutely correct here.
Also of note, your employer should get the permission of the property owner/manager where you will be working. When I first started carrying as a guard, we ran into some problems when the management at one of my assigned posts. Apparently, she had some unreasonable fear of guns because her ex-husband had held her at gunpoint once. (Ironically, I would have been her only protection if said ex-husband had shown up in the middle of the night.)
Anyhow, be aware that there may be a legal issue if the property owner is not aware you are carrying on their property. In most cases, your employer won't want to pay you to carry if she/he is not getting paid for such by the client. However, I know how ineptly some of the securtiy companies are run. CYA.
