I work in a school as a TA. The parents of the school have closed group Facebook pages for most year groups. Inevitably, they sometimes have a moan about the school on them. I happen to know that our Head has spies on some of these pages that keep him updated about any discontent. He will even say in the staff room "You'll never believe what so and so said on Facebook." I feel what he is doing is inappropriate. What do others think?
