So, according to the one person who responded to the article by saying the mother was always a problem and made a spectacle of herself (not that exact wording), it must have been well known in the school that she was on the paperwork to have access to the child...so your arguement is mute.
When a person goes by the office without checking in, it’s not clear who it is that is going by. So, there’s a need for them to be clearly identified. In addition, even if a person is “known” the legal paperwork can change.
That’s happened with me. Something happened so that I had to take a name off the approved list. Now, this person was “known” in the sense that they were seen there before, they were easily “identifiable” — BUT — only the office would have THAT INFORMATION up-to-date. I was thinking that something could happen even 12 hours later after I changed the information. Schools have to be TOTALLY on top of that - even within “hours” if necessary.
And all the other teachers do not have access to that office information, although the immediate teacher does (where our child is). So that means out of the entire school of teachers, there is probably ONLY TWO PEOPLE who know for sure and have up-to-date information. The rest of the teachers only vaguely “know” the person.
SO ... you see ... it’s a very good system for insuring that only the people you designate have access to the child and only the people you designate can have the child “handed off” to them to take out.
