In order to evaluate the preservation and accessibility of public sector collective bargaining documentation in the United States, the authors conducted a fifty-state survey of public sector CBA collections. The study generated relevant data in four key areas: the presence of such collections, the scope of existing collections with regard to covered employees, the depth of those collections when compared to historical collective bargaining in a given state, and the relationship between a perceived legal mandate for collection and the presence of such collections. The authors discuss the public policy implications of their findings, and areas for further study, action, and advocacy.
