I have one parent with no back up. She has been upset at me before for taking time off sick. She thought I would supply a substitute provider on those days (a family member). I have in my contract that sometimes I will for an appointment etc. She seemed to think my substitute would be available all the time. I only use her for when I am away for short periods of time and would never leave the kids in her care for a full day. If I need a full day then I am closed.
She was pretty quiet this morning and didn't say much to me. Ah well, she will get over it.
