This teacher is a typical man of his times. Jaded and cynical desperately clinging to some false notion of self-importance in an education system that left him behind long ago. Sadly he is not respected by staff and merely tolerated as part of the furniture.
He is a good teacher who knows his stuff but should spend less time ranting about behaviour and just try and share his knowledge
More concerned about lording his Faculty Head position over other teachers than actually teaching helping kids. Guy belongs in politics where he can get away with not doing anything, not in schools!
