Set the right example for students; ban adult bullying in the schoolhouse.
Why is this important?
Bullying is used by school administrators to harrass teachers to "go somewhere else." It is not an issue of "improving teacher quality" but an issue of power. Many targets are quality teachers who are admired by colleagues and students. Bullying of adults causes the same psychological stresses as it does for students who are bullied; teachers cannot teach their best when they are being bullied. Bullying adults is not a good model for students; student learning is degraded. If we are to eliminate student bullying, adult bullying needs to stop first.
