Posting here for traffic, I don't have an aibu.
Went to pick up dd from nursery this afternoon and found the whole place locked up and nobody there. After frantically calling, banging on doors, checking nobody else had picked her up we managed to contact the neighbouring school. The staff who were still there were amazing, helped us to get into the building where we found dd on the toilet, on her own, lights off and doors closed, staff gone home. It took us half an hour to get in so she was there at least that long. She was obviously very upset but is now home and fine and drinking lemonade as a treat while I try to stop shaking.
Obviously this is a huge safeguarding issue and there is no way she is going back. The head of the neighbouring school has been in touch and is organising a meeting for the morning.
Any advice on where to go from here, who to complain to? Should we get legal advice? I am so so angry!
