When I was taking classes for my supervisors cert I had an excellent professor who spent a lot of time going over all the work you needed to do to fire a teacher. It was a lot of work, but according to him perfectly achievable. His bigger picture message was that doing that work was important because it gave the teacher ample opportunities to improve but also moved people who didn’t belong out of the classroom. I never became an administrator but that message stuck with me. Most admins clearly don’t have my old prof’s work ethic.
