"[A]n important study of the public sector labor movement's development...To anyone interested in understanding the roots of contemporary battles over the labor movement—as well as federalism and American political development—Walker's book is an essential read." (Political Science Quarterly) "Well-researched and convincingly argued, Divided Unions is timely in its coverage of private- and public-sector labor over a period of nearly eighty years. I can think of no other book that comes close to accomplishing what Alexis N. Walker has accomplished." (Joseph E. Slater, University of Toledo College of Law) "Divided Unions offers a persuasive argument about the impact of federalism and geography on public sector unions that is sorely needed in current public discourse." (David B. Robertson, University of Missouri-St. Louis)
