We have a summer au pair who started with us at the beginning of June and who will be here until the end of August. I told her from the start that we would be away from 28th July to 6th August so she was welcome to take holiday or stay in the house during that time. She then asked if she could take 7 days holiday from 8th - 16th July which was not particularly convenient but I have agreed to and also if she can have a friend come and stay whilst we are on holiday at the end of July. I am firstly wondering if I need to pay her for the time she is on holiday (I was not in fact counting on her taking holiday at all other than the odd day here and there as she is only here for 3 months) and also whether it's reasonable for her friend to come and stay. I did say at the outset no overnight guests etc and am less than keen to have someone I don't know staying in the house whilst we are away. That said, the au pair is very quiet/mature and responsible and has assured me that her friend is the same, and that she has done this with all other families she has au-paired with, so I guess it might be ok. Any thoughts?
