I am a cm who looks after various part time children and I work term time only. I don't charge for holidays. I have a 6yo who comes to me most days and the hours agreed were 7am -9am and 3.15 - 6.00pm including school pickups and drop offs, breakfasts and hot evening meal.
For these hours I charge £12 for the morning session and £13 for the after school, my reasoning being that the morning is classed as unsociable hours. Some days the child comes at 7am, sometimes mum texts me the night before to say it will be 8. Sometimes I am up and ready and they don't come til 8. Mum's shifts vary a lot and I work out what she will pay when she gives me her hours for the week.
I'm not sure if I should be charging her less for the mornings where she tells me the night before as I am then charging her £13 for an hour which I am a bit uncomfortable about. She's a single parent and really struggling with money. If every day was always 7am I think the charge would be reasonable. Should I drop her rate based on the fact that the arrival time varies or stick to my original charge? Hope this makes sense.
