The National Mediation Board (NMB) was established under the Railway Labor Act to facilitate labor relations for railroads and airlines by mediating and arbitrating labor disputes and overseeing union elections. The FAA Modernization and Reform Act of 2012 included a provision for United States Government Accountability Office (GAO) to evaluate NMB programs and activities every 2 years. GAO’s first report under this provision, issued in December 2013, included seven recommendations for NMB based on assessments of policies and processes in several management and program areas. This book examines the extent to which NMB has implemented recommendations made by GAO in December 2013, and incorporated key procurement practices.
