Rude! Here is the clause from my policy. Feel free to adjust it's wording to include your family but we are not responsible for other people's emergencies as long as we are giving 100% every day that we are healthy. As I point out in this clause in my contract, the children in the daycare have usually brought the sickness to my house!

Illness Policy for Caregiver__________

If I am ill I will make every attempt to give parents/guardians 12 hours notice so they may find alternate care for the day. If I am feeling under the weather but not ill I will advise parents at arrival time. I reserve the right to use a paid personal day if I have become ill because usually one of the children has come to daycare with a contagion that has made me ill.
