omeara - don't believe diligent has a clue about teaching. He basis his entire judgement about teachers on his experience which begins that once upon a time a teacher rang him and asked why he wasn't home by 5pm....etc etc etc. Not surprisingly, given teachers' workspace and conditions, most teachers take work home with them rather than stay in a school where there is adequate space, heating, etc. Used to cost me quite a bit in photocopy paper (even seen the queue for the use of the photocopy at school before and after school time), heating, duplicate copy of textbooks which I kept at home, computer expenses, internet use, etc etc etc etc etc. But, don't worry about omeara, he once had a phone call from a teacher he knew.....yeh, right, he knows EVERYTHING ABOUT TEACHING FROM THAT SINGLE PHONE CALL. lol.
