Calif. Teachers Take Action on Homework Schoolteachers in Berkeley, Calif., begin what's called, in union parlance, a "job action." The teachers haven't had a raise in two years. So they're sticking to the hours they're contracted to work. They're refusing to grade homework in the evenings, on their own time, as teachers traditionally do. That means they won't assign much homework. Which makes the school unhappy, though probably not the students.
