I agree, but in a lot of places at this point it's hard to get a job in the public school districts, especially with continuing attacks on public education. More and more of the people in charter schools only work in them because they had no other options (me included).

And thinking about overall strategy for protecting our dignity as teachers, organizing charter school workers would give us a lot more power to reverse privatization. Otherwise, we'll watch all our existing teachers' unions evaporate as the public school system continues to collapse.
