That’s a critical and essential part of what parents expect from the school. They expect that no one will have access to the kid except what is legally allowed, per the parents instructions.
And the parents also expect that the school will “hand off” the kids to ONLY the people listed on that paper that the parents filled out.
That’s not just empty paperwork, that part of the core essentials for your kid at school.
Really? Well that is ok then. They certainly are not actually teaching the child anything but by gosh they are whizzes at making parents sign papers.
And in the end isn't that what schools are for?
To provide union members with money and power for their little egos.
