hello; I had to work with such as classroom teacher. The school board along with the central office staff would write up handbooks full of rules. I will use attendance and tardiness as an example. Miss so many days and the grades, privileges (playing sports for example) will be punished in some specific way.example of an unenforced or unenforceable law, which is to say, no law at all.
So I keep attendance records very carefully and cut according to the rules. The parents complain and the punishment goes away. Sometimes the written punishment is ignored before any parent makes a complaint.
Do not make a rule that you do not or cannot enforce.
