Re: The Au Pair/Nanny employment thread (no ads!)
The rules are quite clear- the Au-Pair has a special status in order to come and learn a new language and experience a new culture- so must not speak her own language in the home. We had several Au Pairs from Switzerland in the past, and I had to guarantee that, although French is my MT, we would always speak English as a family and with the Au Pair. One took the Cambridge First after 1 year having never studied English, and the other passed the Proficiency (now a Professor of linguistics at Michigan Uni- a very clever girl). The rules also stipulate a maximum of 30 hrs per week, with about 50% with a parent present.
In a way, this thread title compounds the confusion between 'nanny' (qualified? or unqualified? a huge difference- certainly in conditions and salary) and Au Pair- which have totally different status.
As long as you speak your local language as a family most of the time, there would be nothing wrong I suppose to ask the Au Pair to help for a couple of hours with her MT- but not on a day to day basis. As said, the whole point of an Au Pair is that they get a chance to learn a new language, and experience a new culture. We had many Au Pairs here in French speaking Switzerland, when I was a kid- to help my part-time working mum and learn French (so they can be of the same country, as long as the language spoken in the home is different).
