I worked as a relief PA to disabled people for 2 years, self employed. I found every single client had been robbed by carers or cleaners. This includes my DILs late grandmother who lost multiple items during her last terminal illness. Items taken included sheets, duvet covers, joints of frozen meat, coffee, dishwasher tablets, jewellry, money, cashback at shops and petrol stations, wine and spirits, clothing, cameras, binoculars, ornaments, perfumes, boxes of biscuits etc. One lady had all her washing stolen by the carer who washed and dried it. Most people didn't even bother to report it as they were desperate for a PA.
I would not have a carer or cleaner without setting hidden cameras in every room.
