My colleague has told me she pays less than min wage for her live-in nanny. She is Latvian, and the nanny is Latvian also - possibly with no English. My colleague said she doesn't need to pay min wage as she provides accommodation etc, but I really don't believe that's the law.
It's also suggestive that, if not min wage, then it's unlikely that proper payslips are being given, and tax paid etc.
Would you do anything about this?
