Urban teachers unions, as mature institutions, face three dilemmas. First,
they struggle to maintain their ranks through an active role in the prepara
tion/recruitment of new teachers while raising standards (limiting supply)
and thus raising demand and salaries. Second, unions seek to become a more
powerful national voice for teachers (by attempting to merge the American F
ederation of Teachers and the National Education Assocation while serving t
he local district needs of their membership. And finally, and most complexl
y, unions strive to preserve large, monopolistic public education while bei
ng aware of the need to reform, restructure, and even privatize schools to
drive improvement.
