Teachers, never let family time be shortchanged. If something happened to you, they would replace you fairly quickly at school but you're irreplaceable at home.
The culture of a school is created by everyone in the school. Walk in a school and see how the front office staff talks and interacts or the staff /teachers in the hallway. Yes the admin influences it but everyone is ultimately responsible for a positive school culture.
The students' learning environment is the teachers' working environment. When teachers feel supported, encouraged, valued, and appreciated, they will create a dynamic learning environment. Then students and teachers can thrive!
