Yesterday was DC's 1st day in Y1 and my first day back at work after mat leave (WFH). I'd negotiated taking a late lunch to allow me to pick up DC from school. The teacher kept them all behind for 15 mins. When I asked DC (admittedly not necessarily a reliable witness) he said some of the children at the back of the queue were being noisy and the teacher wouldn't let them all our until they stopped messing around. AIBU to think this was unreasonable on the teacher's part? I was 15 mins late logging back on to work on my first day back - presumably other parents had similar commitments/potentially other kids to collect. I'm still quite new to being a school parent so keen to hear other people's thoughts before potentially mentioning something to the school (if this happens again). Ta!
