Hear hear seeker.
I also think the issue is more about the op being seated in the school office, rather than the actual document. Ideally, every school would have several small meeting rooms, where no paperwork ever needs to be left. Parents should never be allowed in either the school office or the staff room- which after all, are other peoples places of work, where confidential information will be held, and discussed. After all- who would dream of ever being allowed to sit behind the reception desk at the doctors while filling in form? Or in their staff room??
However, in the real world, most schools dont have that luxury. They are also under enormous pressure to be open and welcoming to parents who want to volunteer, in a way that no other profession is.
As a parent I have occasionally had meetings with my dds year head in her office - the school is pushed for space, and doesn't have the luxury of unlimited consultation rooms. The desk usually has papers on it. I have no idea what information these contain, because, surprise surprise, it's none of my business, I am there to discuss my child, and I damn well don't try to read anything. If I inadvertently saw a piece of paper headed 'safeguarding' I would assume it was a document merely outlining safeguarding procedures- ie not anything confidential. But again, I wouldn't know because I wouldn't read it.
What sort or person does?
