Then again there will probably be some silly computerized system for attendance set up by some IT bod which if its anything like some schools doesn't work half the time staff arn't trained how to update it and it prints the twagging letters off automatically,
If you had to sign 150 letters about poor attendance would you read each one? On top of the other mountain of paperwork you have to do Dealing with kids who have been kicked out of classes, parents complains, and general running of the school?
my mothers is a teacher and its ridiculous the amount of paper shuffling they have to do on top of marking kids work,
planning for lesson,
Filing kids work,
Designing things to put on the intelligent white board (where as at one point you'd have written it in chalk during the lesson)
evaluating each lesson,
kids personal profiles,
collating Exam/test results,
That on top of actually trying to teach.
you should see the mountain of work my mum comes home with every night she must spend 2 hours at home jugling papers and most of saturday night and most of the summer holidays sorting out the class room and paperwork for the new school year.
Look at how many other organizations send out letters, my grandma still gets letters from companies addressed to my Granddad, who has been dead nearly 4 years despite informing them they still come through the letterbox as his name must still be on the database somewhere and no one has taken it off.......
