The basic principles I imposed to my children regarding school were:
School rules must be respected!
School work must be carried out!
It was not always easy to follow those principles. Some rules were inadequate, some teachers did not respect the rules while dealing with children, and often, my children did not respect those rules.
Fortunately, there were no rules that went against the children. The behavior regulations concerning teachers and children were, as always, there to provide stable working conditions and to help in achieving the best results.
We interpreted the rules in our own way, and so did the teachers. Most of the teachers had the correct interpretation, but some of them acted inconsistently, sometimes wrongly and very harmfully for the pupils. In those cases, I would always warn the class parents about the possible consequences and propose possible solutions. About how it would turn out you read in the post titled Parental meeting also known as Dance of the Vampires.
