Do they want the bus driver driving, or monitoring the behavior of the children. You can’t do both jobs well. If he had gotten into an accident dealing with this issue, I don’t suppose they would say he did the right thing. If they need the children’s behavior they need someone besides the driver to do it. (If he pulled over every time he needed to address something, the children would deliberately have him starting and stopping to get to school later)
Its for the children doncha know.
