Anyways, I don't see why they wouldn't be able to use a retired volunteer. I personally would never allow them in if I'm not there though, I don't trust people and don't want them looking around places where they shouldn't be, as may well have happened with the guy in your apartment.
Yes. Once every 6 months for 3 weeks. It’s terrible.
Well I question it due to the risk of having a non-employee doing work for them since they’re neglecting their job to use real maintence vs a volunteer that puts them in potential legal liability
