I have just re-opened after moving and a bit of a break. My hours are 730-5. I have had a lot of inquiries from shift workers like nurses, and I've decided that if they request a 630 start it's okay with me as long as they understand that I charge $10/hr extra after 4pm. So they pay for the same number of hours as the later starters. If they need later then they pay for it. I'm not just extending hours for nothing.That's not fair to me or the other parents who stick to my posted hours!
After reading another string about part time kids, I also decided that if the schedule is erratic because parents works shifts then their fee is $50/day. A lot of time they will only be coming for 10-12 days per month so that helps cover the days I may not be able to fill. So I charge $40/day for 5 days, and ten dollars more for less than 5 days. I think I'm okay with that....for now.
