Whether it's your own children, your students in the classroom, the teachers that you manage or the administrators that you manage as superintendant, you need to think about what and who you're supporting.
At home if you let one child bully or tees the other, there will be long term trust issues with you and that child. You also run the risk that your children will not be as close as adults because of the tension you seeded or let happened from a difficult childhood.
In the classroom if you don't stop students from bullying, teasing or intellectually intimidating others, school will seem unfair. As the teacher you need to defend the other students. Like at home the adults are in charge. The young person is not really empowered to defend themselves. We have all been in that class where one student monopolies the time by talking or disrupting and the teach does nothing to curtail this disruption.
Parenting and Teaching are two areas I know and have been on both sides as brother/student and parent/teacher.
I think Principles need to protect the teachers and tell them to “take a step back” or “look at the bigger picture” parents and teacher do this all the time. It's harder, they have anywhere from 20 to 200 teachers. I worked 17 years in a teacher run school, I have been the innocent victim and the provocateur many times and the principals that got to know me were the ones that used my skills the best.
As far as institutional oversight of managers and administrators, if these people ever come the the Superintendent to suggest: “if we could just treat everyone the same” or "my job would be easier if we had one rule for everyone " those managers are not doing their job, and the “Super” is not doing theirs if they implement a course of actions or rules that make it easier for admin and harder on the students and teachers.
The common connection here is: if you are responsible for people, you need to get to know them, see what they need to thrive and protect them. I do that with my two sons and they are awesome, and with my students and they made great work. Never cut corners when you are charged with managing people.
