I have a nice au pair who is honest and kind. My au pair wanted find some extra work in her spare time and in order to help I put her in touch with a friend of mine who wanted some help with the housework, cleaning and childcare over the weekend. Friend of mine agreed to pay her a fixed amount for the work which my au pair agreed to. However as no set hours were agreed, my friend had her there for a long time which meant my au pair was working for approx £5 per hour. My friend wants my au pair to work every weekend now, but I can't help thinking that my au pair is being taken advantage of, as a cleaner would get almost double this. On one hand I think I should stay out of it - after all it is between my friend and my AP, and I guess my AP is happy that she is at least earning something extra - but another hand I feel uncomfortable about it all. Am I worrying about it too much? Should I just leave them to it, or should I say anything to my ap??
