Look who is talking! You don't know everything either. I know first hand what its like, most high school teachers teach 3 classes in a single day at 70 minutes each that is 210 minutes of teaching which is 3 1/2 hours a day times 5 days = 17.5 hours which leaves 22.5 hours of lesson planning and marking, they get paid for their lesson planning and marking which is done at home or at school after hours, most teachers are done there planning and marking in 2 1/2 hours. 6 hours of work a day. Also don't forget the sick days, which they are entitled to 15 a year, which is equal to another 3 weeks of holidays and believe me they use them even if they are not sick. Sure they volunteer and other shit but they do get paid a hefty amount so they should stop their crying about class sizes etc. on the other hand auto workers don't get paid for sick days and they work even harder than most teachers if not all of them. Also i think teachers with 10 years make over 75 000 a year or more thats more than an auto worker without overtime.
