I would like to set my nanny up with a credit card to deal with the various expenses that she deals with. She is extremely trustworthy, so I am not particularly concerned about her defrauding me (or perhaps it would be better to say that I would be concerned about her defrauding me but see it as extremely unlikely). However obviously there are the usual checks and balances which I would like to have in place with anyone (including DH!) who I share a credit card with.
I would be interested to see what anyone else does. For example do you take out a credit card in your name with a low limit and then give the nanny a second card on the account? Its really to deal with petrol, runs to the supermarket and eg picking up the odd bits of clothing without me having to deal in wads of cash.
