Three years after Barack Obama's election signaled a seeming resurgence for America's unions, the landscape looks very different. Republican governors in Wisconsin, Indiana, and Ohio have limited the reach of collective bargaining for public employees. The moves, especially in Wisconsin, set off a national furor that has all but obscured the underlying debate as it relates to schooling: Should public-employee collective bargaining be reined in or expanded in education? Is the public interest served by public-sector collective bargaining? If so, how and in what ways? Arguing in this forum for more expansive collective bargaining for teachers is Richard D. Kahlenberg, senior fellow at The Century Foundation and author of "Tough Liberal: Albert Shanker and the Battles over Schools, Unions, Race and Democracy." Responding that public-employee collective bargaining is destructive to schooling and needs to be reined in is Jay P. Greene, chair of the Department of Education Reform at the University of Arkansas and author of "Education Myths".
