I live in Ohio (and I'm not a lawyer in any case), so I won't presume to advise you about the legality of the situation, but I have to wonder how your employer reasonably expects you toguard/move cash without one? Either they ought to have provided an opportunity for you to obtain a carry permit before you started (and even helped expedite the process if they're supplying "armed" guards), or explained that you didn't need one in the course of your duties, whichever applies. Completely asinine that this would be at issue after the fact. Personally, I'd go ahead and carry under the circumstances and risk a charge before going naked with a cash-hauling job. There may be a "reasonableness" standard that affords you an affirmative defense to a CCW chargein the Michigan criminal statutes - which is not to say that the authorities might not still have a basis for making a complaint - just that you might be able to beat it in court that way.Ohio had such an affirmative defense available to people doing hazardous jobs like that before they recently reworked the CCW laws. Ask your boss and/or check with a lawyer.
