"Frank Chalk is a teacher in a fairly poor inner city school - a school where the kids get drunk, take drugs and beat up the teachers...when they can be bothered to turn up. He confiscates their porn, booze and trainers, fends off angry parents and worries about the few conscientious pupils. Terrifying and hilarious, It's your time you're wasting is Chalk's real-life diary from the front line of the modern edukashun system."--Provided by publisher.
