They are one of the key swamp operative unions..

They have power because parents feel that good schools are important and that teachers are saints and therfore if they strike the parents (taxpayers) reflexively support the teachers.
But I suppose in a world where schools are kept closed indefinitely because teachers say they'll strike if they are forced to teach kids there is a tipping point where parents will say 'enough' and finally tell the teachers unions to go f@#@ themselves. Then change is possible.
Sadly I don't think we're there yet.
