Middle school teachers and administrators: what are some of your campus-wide procedures/logistics?

I work in a 1500+ high school, and we have three very spread-out buildings.

Before school, all students report to the cafeteria until 7:55. Then they can walk the halls until school starts at 8:20. ALL teachers are on duty in various locations during this time (and between every class and after school).

After school, bus riders and parent pickups are dismissed at 3:00. Drivers are dismissed at 3:05. All students are to be out of the building or in a supervised after-school activity by 3:15.

In the lunchroom students are to be seated unless in line for a meal or throwing away trash. There are always a principal and two teachers on duty. There's a teacher on duty outside all the restrooms between all classes. Our assemblies are silent. Totally. If a student talks, he is removed from school for the day. We teachers have an exact spot we must supervise. We are scattered throughout the stands.

We are held accountable for all of these duties. We must do them, and we know it.

Um, no. Bullying, the kind of bullying that leads to severe depression and suicide at any rate, is not generally an obvious out in the open kind of thing. Most teachers are not any more aware of the bullying than the parents of the bullied child (or bullies). And even if/when they are, their hands are often tied by red tape that prevents them from doling out consequences to the bullies that would actually have any real effect. Not to mention that much of the school-associated bullying happens outside of a school setting where a teacher/administrator would have any kind of authority (this I know from personal experience of being bullied as a child by other kids at school).
