A teacher writes:

I am a union member (AFT affiliate) and nothing in our union contract requires that I teach a certain way or limits the extent to which I stay late, come in early, or take work home. We do have limits on class size (28). Doesn’t this seem like a good idea for children as well as teachers? The only people who seem interested in constricting my work are the occasional administrators/suits who appear now and then with a stack of tests which I have to foist on my students.
