Can you tell us your old and new policy?
Our school is right next to a church. The church has a circular drive all the way around it. There is parking on either side. The old policy allowed parents to either park their cars and walk over to the end of a long sidewalk and wait for the students, or to get in a pick-up line that allows parents to remain in their cars. People are not allowed to park on the side of the church closest to the school to keep the area open for parents who are driving through and to keep it uncongested for the kids. When the bell rings, the teachers take turns walking the students down the sidewalk and anyone who has walked over to get their child, those kids are dismissed. I'd say this accounts for half the kids. The other half of the kids are dismissed as the teacher sees their car. Those are dismissed three at a time. I thought the system worked quite well.
The new policy is that the parents will all have to park now and walk up the sidewalk and wait outside the door to pick up their children. I have heard many reasons for this change, and maybe if they were consistent, I'd be handling this better. Some say that they don't want to have to worry about the liability of opening the car doors for the kids. Well, just don't open the car doors. Make it clear that that isn't going to happen. There is one other reason, that would have a simple solution (not sharing that one for safety reasons), and my favorite is that they don't want the kids to have to stand in the rain. So, instead, the parents will have to stand in the rain, wait for their kids, and then still walk their child in the rain to their car. So, the kids will be in the rain just as much. The parents will be in the rain a lot, because there is no shelter waiting outside the school. The only one this is going to benefit is the teachers who don't want to help anymore. It rarely rains. If anything, it is cold in the winters, and the kids all wear winter coats, hats, mittens, etc.
My biggest concern is for the parents who will have no option to get their child but to walk up that sidewalk. It does get slick in the winter time. And, elementary kids can handle that better than some of our older parents, grandparents, or people with infants or preschoolers.
