Visiting a primary school recently, I was perturbed to see children in a mixed year 6 changing in their classroom, with their male teacher present, and with me present, who they did not know from Adam. It made me very uneasy, not because I am a perv but because it seems to fly in the face of all the child protection issues we have to comply with today. The flip side of these is that as an adult working with children you need to be able to demonstrate your own complete innocence, at all times.
Be interesting to hear if others have had similar experiences or whether this was a one-off.
