We are going away for the weekend without children, and our au pair/mother's help has kindly offered to look after our two for the whole weekend. To get a feel of how much I should pay her for the weekend, I asked a friend who has an au pair, and regularly goes off for a week or weekend, leaving her 7 year old DD with her au pair, how much she pays. She told me that she never pays her au pair for babysitting in the evening (even at weekends) and never pays her extra when she goes away either. She also pays her under 100 euros a month less than my au pair (which is significantly less than the going rate) and contributes nothing towards the cost of her language classes or flights to and from her home country in the summer/at Christmas. She justified this by saying that she doesn't expect her au pair to work when she herself has a day off, so counts this as time off in lieu.
Am I just remarkably soft, or is she really taking the piss here? She goes away regularly for work and once left her DD with chicken pox for a week with the au pair while she went ski-ing.
And more to the point, why does this au pair stay?
