In dealing with teachers back in the 1980’s, I always went directly to the Principal then the Superintendent and then the School Board. My girls’ teachers knew from 4th grade on how I dealt with issues.
Most Liberal teachers pull stuff when they think the parents won’t do anything about it. When they find out you will, they’re really careful from then on out.
I am a teacher and I find this story appalling. I teach in a district in the south and every child is EXPECTED to use sir & ma’am.
What I don’t understand is your being so disrespectful to your children’s teachers. To not address them first as you boasted is not the way to model for your children or build a positive relationship with the teacher. In all my years of teaching I have never been in a position where the parent & I could not work thru any issue. By all means a parent should go to the principal immediately if you are unhappy about what is happening and talking with the teacher did not immediately resolve the issue.
It is bizarre to me that you would treat an adult like that. And by the way when a parent came to me about a situation where I thought the teacher to be completely in the wrong I told her to go to the principal and if the problem still did not stop to go to the superintendent.
