Ahh it's getting ugly....short payment

[Play and Learn]

And then you state that a termination letter will be written up if they can't come up with the shorted days.

Do you have it in your manual/contract with their signatures of this rule?

In my manual under the Illness Policy (it's bolded and capped):

Regular child care fees apply for all children in times of illness.

I also have in my manual (which they sign) under the Fees section, and in the Contract (which they also sign) that they HAVE to (again bolded and capped):

Payment for late fees is due at time of drop-off the next day with exact cash or cheque or your child will not be allowed to come to care. If payment is late, I will require a $20 late fee per day. Each day that you do not pay, your child will NOT receive care.

This pushes them to RESPECT me and my business, and that I do NOT put up with bullshit like your DCM is pulling.
She would get a termination asap from me, unless she wants to fork over the money. She's paying for the child's spot, no matter what! The only time parents do not pay for care is when I have to close.
