Looking for some views on au-pairs having guests over. We have always encourged our au-pair to have friends from home or family to come and stay. When our current au-pair's family came to visit we offered them to stay either with us and come for dinner (they choose to stay in a hotel centrally but came for Sunday lunch). We have told our au-pairs that we don't want them to bring friends back to the house whom they have just met without telling us.
My question is - our current au-pair has made friends with other au-pairs and brings them home after clubing to our house. She also stays at other au-pair's houses after partying. Is this quite normal?
She goes clubbing and drinking every week and recently brought a friend home who was vomiting all night.
She seems to equate friends she has known 3-4 weeks with the friends we have agreed to stay with us from home.
My main question is - does other au-pair families allow their au-pairs to bring people back to their house after parties?
