How do you know the person that set this you up?
I'd be ending that friendship too! I suspect they know EXACTLY what he's like!
I strongly suspect having worked in elderly care myself that the reason you were sought out is because he's burnt all his bridges with local professionals precisely because of his sleazy behaviour - nobody will work with him!
Do not under any circumstances let your dc anywhere near him he sounds predatory and dangerous
Also report him for the drunk and dangerous driving before he kills someone! To the Dvla and keep reporting to police why they aren't responding to this I don't know
Be careful how you do things....he could contact the authorities if its cash in hand.
I wouldn't put it past this guy to accuse you of stealing/financially abusing him
You've put yourself in an incredibly vulnerable position in this job even though you say you've no caring responsibilities here what if he had an accident due to where you moved something? Have you even got public liability insurance for such an incident?
It makes me wonder why his dc aren't keen to spend more time with him or go away with him.
Again they know exactly what he's like!
He actually reminds me of my dad (who abused me) just because he's elderly doesn't make him an innocent, I had very little to do with him as an adult but other people didn't know why specifically.
My dad was charming, intelligent, funny, entertaining, incredibly generous (when it benefited him)
He was also controlling, jealous, possessive, aggressive, violent and predatory
Nobody is "all bad" and abusers KNOW they have to charm to reel their targets in.
