I can verify the comments already posted about this man. He is a liar, a cheat and a bully. The school would be okay if he wasn't there. The word 'honesty' is not in his vocabulary and he will find a thousand excuses for not honouring any contract, i.e., paying wages, providing facilities, etc.
He is a moron who THINKS he is clever but all the staff know what he is... a dishonest, narrow-minded, deceiving, bad-mannered, lazy, ignorant, fool.
