This really is amazing and I applaud you for how you treat the teachers. Some of the issue may be the principal. The teachers have almost no time for themselves during the day, sometimes no time for a bathroom break and/or eat lunch. They have meetings after school 2 times a week and her typical day is 7:15-5:30. Then home to grade. I tell my wife this does not sound normal, nor should it be considered normal. She teaches at a challenging school. While our ISD and our area is mostly middle/upper middle, her school(in same ISD) is in a poorer area where about 50% of the kids have an unstable home life, and live near or below the poverty line.
