i was in school today at lunchtime and watched a teaching assistant telling off a reception boy in the dinner queue. He was clearly being disruptive and cheeky but her approach was to shout angrily and harshly into his face, much as a very irate mum at the end of her tether might in the privacy of her own home . Is this OK? I didn't like to see it coming from a professional, but I never feel confident that I can judge what's considered 'normal' by other people. And what should I do, if anything? She was in front of any staff who happened to be present and lots of children, so it can't be that unusual.
