The Free Workers' Union of Germany (German: Freie Arbeiter Union Deutschlands; FAUD) was an anarcho-syndicalist trade union in Germany. It stemmed from the Free Association of German Trade Unions (FDVG) which combined with the Ruhr region's Freie Arbeiter Union on September 15, 1919.
The FAUD was involved in the revolution in Germany from 1918 to 1923, and continued to be involved in the German labor movement after the FAUD began to decline in 1923. After 1921, the FAUD added an "AS" to their name, signifying a full transition from simple syndicalism to anarcho-syndicalism. This also led to further difficulties between the intellectual elites of the FAUD (AS), such as Rudolf Rocker, and the rank and file workers, mostly in the Ruhr region, who were more worried about "bread and butter" issues than anarchist political activities. These workers, the majority of the FAUD-(AS) members, formed the Gelsenkircherichtung (Gelsenkirche tendency) within the movement, and given the movements federalist structure, began to drift away from the FAUD-(AS) intellectually and organizationally. Eventually, those workers who had joined during the revolution left the movement and the remaining FAUD-(AS) members came from the FDVG's original constituencies of the building trades and specialized textile workers.
