I'd be careful about the workplace too, don't want to stray too far off the main question, but fortunately, my place of work is one where it is extremely unlikely I'd have a confrontation (classified DoD work with a security force)...so I keep it locked in the truck. Since your business takes you to residential areas, I would probably carry. I know that a lot of mental patients don't exactly live in the "Leave It To Beaver" or "Nelson Family" type neighborhoods. I would assume that if your "patients" were of any type threat, they'd be in a "facility" with security. I would be more concerned about the area of town and the neighborhoods you'll go to. Therefore, like a few previous comments, I'd be more concerned abouting ability to adequately protect myself, and possibly the patient, than some company rule that is more applicable to the corporate office environment. Frankly, I think they are more concerned about someone going "Postal". But, as any reasonable person could conclude, if someone is going Postal, a frickin sign or rule ain't gonna stop them ! Pick an appropriate sized pistol and use an ankle holster. For Winter time, when a light or heavy jacket is used, the possibilities are unlimited....consider a shoulder holster rig......There.....my nickles worth.
