Nanny has X amount of holiday in their contract. Nanny picks half, family pick half.
The family 'use up' their allowance and then book an extra two weeks holiday, which they give to the nanny as extra holiday.
The nanny then books a holiday/makes plans for these two weeks.
Due to an issue at work the family then have to cancel their two week holiday (about 2 weeks before they're due to take it) and will now need childcare during those two weeks.
Is the nanny obliged to cancel their holiday/plans? Or to take it out of their annual holiday allowance (the nanny still has one week left to pick, no holiday booked for that time, but one in mind)? Do the family have to honour the holiday?
