Name changed as could be outing.
A is a childminder and b is a client.
B has a term time only contract and pays a £45 retainer a week for 12 weeks of the year. A gave b the option as per the contract to have childcare during that time if needed and pre agreed. Any extra hours would be added to the invoice.
A is sick and has had to close so b cannot have 2 days childcare for this week as previously agreed. A does not get sick pay. A has said that they will refund the childcare fees for those two days but will keep the £45 retainer as b would have had to pay that anyway. B says that two days were missed and other arrangements had to be made. Who is right?
