text: My third reason is that some parents may not want their children to do community service. Some parents have busy work schedules and they may not get to see their children that much on the weekends, so they spend time with them on weekdays after school. Or, some parents might share custody of their kids and they might want to go see a movie with them or get something to eat after school when it's their day to be with them. If schools started making them do things after school, the parent could miss quality time with the child.
