Private schools often discount tuition for the children of their teachers, sometimes substantially. I knew more than a few teachers at my high school who taught until they got pregnant with their first child, quit until the youngest was in elementary, then went back to teaching - both to have something to do and to defray the cost of tuition. And while the students and parents may not be perfect gems, they're a lot less likely to threaten actual physical harm.
