We have this service called 241-KIDS, where you're supposed to call if you know that a child is being mistreated, but the system is overloaded and there is no help for the children.
I worked in a school and there were children who would get dropped off at the bus stop and winter and summer and the parents wouldn't be there to meet them. The children would have to wait until the parent got off work. Calling the 241-KIDS didn't do anything. A very sad situation.
