The moment you let someone into the building, you have *allowed* them in.
The school employees have the ability to *NOT* buzz in someone if they deem it necessary to the safety of the children.
That they choose NOT to and instead insist that the real protection comes from a magical piece of paper is their problem.
How are you coming on establishing how a mother checking on her own child is a danger to other students?
You only open the door to allow then into the office to check who they are and to verify by the records that they have permission to access the child. That is not done at the door, but in the office, where the paperwork resides.
You said ... “How are you coming on establishing how a mother checking on her own child is a danger to other students?”
The mother may be a danger to her own child or to others ... either way.
If the office didn’t stop the mother of our boy from having access to him, then they would be negligent and we would sue the school for not doing their legal and required duty of stopping and checking everyone with the records to see if they are allowed access to a child in the school.
