This document discusses the history and future of public sector bargaining and unions in the United States. It traces the rise of unions from the 1930s in response to poor working conditions, through the growth of collective bargaining laws and public sector unions. However, it argues that public sector unions now have fundamental flaws, as they are not subject to the same market forces as private sector unions. It claims that unsustainable pension and benefit costs are being driven higher through political lobbying by powerful unions. The future of public sector bargaining is uncertain as these costs grow rapidly and place major strains on government budgets.
