Not sure how you would word that. But whenever I know that a parent isn't working and still sending their child I always ask if it will be the usual pick up time. Then I know what to expect and they are held to a particular time.

We have lots of extreme weather here in Manitoba and unless I have no power or something my daycare is open and the parents can send their kids as they are paying for the spot. Though it takes alot for anyone here to not go to work because of the weather.
