Unionize the Charters!
One of the best strategies for dealing with the union-busting charter schools is to unionize said charters. That is happening, especially in Chicago. There are difficulties in reconciling an anti-charter position with organizing those teachers, but the unions can work that out. Unionizing these schools are the nightmare of Michelle Rhee, Campbell Brown, Arne Duncan, and Scott Cowen. That alone should make it a top priority.
