This doesn't apply to me but some of my friends have had an au pair whilst on maternity leave and now see them as the cheap solution for childcare. They think just by increasing the au pair's pay from eg £120 to £200 they can ask the au pair to do 45 hour weeks.
The U.K. Gov website is not v helpful.
When is an au pair not an au pair? When would you have to pay national living wage? (We all live in London.) I won't be sticking my nose in - but am curious.
