This book explores why the Swedish Social Democratic Party (SAP) and the allied Swedish Confederation of Trade Unions (LO) have been reluctant to embrace calls from employers and bourgeois parties to liberalize Sweden's restrictive third-party national labor migration policy. Gregg Bucken-Knapp shows that the SAP and LO evaluate proposed labor migration policy reforms on the basis of whether they are seen as consistent with, or threatening to, the Swedish model.
