Same, but I actually just leave a door unlocked. I live in a very low crime area and I have a security system, when they come through the door it sets off the 60s timer for them to deactivate the alarm with a punch code (which I supply to the agency and I guess they keep on file); they have standing instructions to lock the door when they leave, which they have never failed to do. The security system stays disarmed though, which is fine–I am not super paranoid about home security.
While I would obviously not just tacitly allow it, I don’t worry too much about a cleaner stealing while unsupervised in my home. I don’t have a lot of sentimental items, expensive or etc items (guns and some watches) that would be prized by a thief are kept in a heavy locked safe, and I don’t keep any real loose cash of valuables laying around. Most of the expensive stuff in my house that isn’t locked up is too big to easily move.
I will say though, a good friend of mine got married about 7 years ago and bought his wife a ~$40,000 engagement ring. The wife is an attorney who does a lot of work with indigent defendants, and a woman she met through some of her outreach along those lines ended up becoming their cleaning lady. She had cleaned for them for a few years, but one day the ring disappeared after one of her visits. She also went dark on them and wouldn’t answer phone calls for a couple of weeks. They searched around local pawn shops and monitored eBay to see if the ring went up for sale, but no luck. They actually just ate the loss entirely, even though it was insured–the wife didn’t want to file a police report on the cleaning lady and insurance wouldn’t cover the loss without one.
