By this I meant hall duty assignments, its not so good that they can decide this is not part of their contract.
I agree that schools should teach valid history, and they could even discuss whether lockers should be private, or remain the property of the schools. You could review the search and seisure laws and see whether they apply to school age kids, and under what instances the school authorities may search a kid's backpack.
Your answers sound like it would be tough on teachers, but I guess you can have the point. Kids in decades past were not searched by school personnel I guess? What age would you say the bill of rights applies? What about parents looking in a kids room? How far does this go?
