Federal Mediation and Conciliation Service

The Federal Mediation and Conciliation Service (FMCS) is an independent agency of the United States government that provides conflict resolution services to private and public workers and employers, including mediation services for parties who cannot resolve a collective bargaining dispute. The agency aims to support the economy and workplace environments by resolving disputes that threaten the free flow of commerce.
It is not a regulatory agency.
Founded in 1947, it is the nation's largest public agency for dispute resolution and conflict management, providing mediation and related conflict prevention and resolution services in the private and public sectors.
