My sister is about to employ someone to look after her baby girl, 9 months. This girl (aged 22) is an experienced nanny and former nursery nurse, and has become quite close to my sister, as she babysits regularly and has got to know the family very well. She absolutely dotes on both my niece and nephew, and she's a really lovely girl.
My sister has said to her that she'd love her to look after her DD but can't afford the nanny rates. (DD is currently with a childminder) But as this girl now has her own baby, she's said she's quite happy to look after her DD, in their own home, just like a nanny, but on childminding rates (£5 per hour) if it means she can bring her baby along too. Sounds too good to be true huh?
Only problem is, the girl has asked that she's paid cash in hand, obviously to make up for the fact that she'll be on a much reduced rate.
I'd appreciate thoughts on this. The girl obviously knows she's not entitled therefore to national insurance contribs, sick pay, maternity pay etc, but she's SO keen to work for my sister and to look after her DD that she doesn't seem bothered by this. Apart from the obvious MORAL issue of not paying tax, what other problems should she consider?
