Federal Mediation and Conciliation Service (United States)

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. FMCS provides training and relationship development programs for management and unions to promote labor-management cooperation. The agency also provides mediation, conflict prevention, and conflict management services outside the labor context for federal agencies. The FMCS headquarters is in Washington, D.C., with nine field offices across the country.

On March 14, 2025, President Donald Trump signed an executive order that called for the elimination of non-statutory components and functions of several government agencies, including FMCS, "to the maximum extent consistent with applicable law".
