I agree. Behaviour was bad enough 10 years ago but it's far worse now. The last 10 yeras have seen the development of Pupil Voice, whereby pupils are even used to observe lessons and pass judgement on the teacher. Pupils are on job interview panels. In some school's a pupil's ersion of a classroom incident is given equal weight with a teacher's and sanctions imposed by the teacher may be cancelled if no-one else in the class will be a witness. The end result is that pupils know that they can misbehave with impunity and feel that's it's always worthwhile coming up with a story to counter the teacher's account.
