I did have a cleaner who skived off after two hours when paid for four- as I discovered when I ran into her while out shopping!-I would find the house pretty clean, but probably only superficially. I wasnt sure how to handle it but she left anyway, and Ive had the same cleaning lady now for ten years. She always does her time, the house is very clean, she's helped me reorganise my mess after builders, she babysits and is trusted completely. During the hols, if we are away and so not there to make a mess she comes in and does other jobs- fridge cleaning, spring cleaning, carpet cleaning so she doesnt loose out. I pay her a tenner an hour and she earns it!
