Overview
The Revolutionäre Gewerkschafts-Opposition (RGO) was a communist trade-union organization associated with the Communist Party of Germany (KPD) and the Communist International during the final years of the Weimar Republic. It emerged from communist efforts to challenge the established free-trade-union movement, particularly the Allgemeiner Deutscher Gewerkschaftsbund (ADGB), and to organize workers around a more explicitly revolutionary program. The RGO’s formation followed a period of conflict between the KPD and the Union of Manual and Intellectual Workers, an organization that contained many KPD members but was regarded by the party as insufficiently disciplined and unsuitable for its strategic objectives. After the Communist International and the Communist International’s trade-union affiliate, the Profintern, adopted an ultra-left orientation in the late 1920s, communists increasingly treated the Social Democratic labor movement as a rival associated with so-called “social fascism.” The KPD consequently sought to build a separate organizational base inside and alongside the existing trade unions. On 14 March 1929, the KPD central committee decided to admit workers who had been expelled from established unions for radical activity. In June of that year, communist metalworker Michael Niederkirchner was expelled from the German Metal Workers’ Federation. He subsequently established an aid organization for expelled militants, which became an important nucleus of the RGO. The KPD formally created the RGO in December 1929. Although it was presented in 1930 as a “red class trade union,” it was never able to replace the established unions or create a broad, autonomous communist trade-union movement. The organization’s relationship with the existing unions changed during the early 1930s. At first, the RGO promoted separate communist structures and supported campaigns intended to draw workers away from the ADGB and other established bodies. After communist influence declined because of resignations and expulsions, the KPD modified its approach in 1931. Communists were instructed to work as an opposition within existing unions while also strengthening “red associations” in key industries. The largest such bodies were associated with metalworking, mining, and construction, but each remained a very small presence relative to the overall workforce. The RGO reported approximately 250,000 members in 1932, although contemporary assessments noted that its accounting practices emphasized admissions and did not fully reflect departures. More than half of the organization’s reported membership was unemployed, limiting its ability to operate as a conventional workplace-based union. Its leaders generally emerged from the KPD’s trade-union apparatus rather than being elected through ordinary union meetings. The RGO received national attention during the Berlin transport strike of 1932. It supported a wildcat strike against the Berlin Transportation Company after wage reductions and acted in cooperation with the National Socialist Factory Cell Organization, the Nazi labor organization. This joint action reflected the RGO’s hostility toward Social Democratic trade-union leadership, but it also became one of the clearest examples of the dangers and contradictions of the KPD’s ultra-left trade-union strategy. After the Nazi seizure of power, the regime destroyed Germany’s independent trade unions. On 2 May 1933, the SS and SA occupied the offices of the ADGB and its affiliated unions. The RGO went underground and maintained clandestine activity for roughly two years, but the Nazi security apparatus eventually dismantled it in 1935. Postwar attempts by Maoist groups in West Germany during the 1970s to revive the RGO name and model achieved little lasting success. The historical RGO therefore remained primarily a product of the Weimar-era communist labor movement rather than a durable trade-union institution.
History
The RGO developed from the KPD’s attempt to resolve a strategic problem in the German labor movement: how to build a revolutionary communist presence while the established trade unions remained under predominantly reformist and Social Democratic influence. The party had previously tried to use the Union of Manual and Intellectual Workers as an organizational vehicle, but disagreements over discipline and political direction eventually ended that relationship. The international communist movement’s turn toward an ultra-left policy after the 1928 congresses of the Communist International and the Profintern encouraged the creation of an independent communist trade-union opposition. Social Democratic organizations were increasingly condemned as “social fascist,” and the KPD began constructing a faction within the ADGB. In March 1929, the party authorized the admission of people expelled from unions for radical activity. Michael Niederkirchner’s expulsion from the German Metal Workers’ Federation in June 1929 led to an aid organization for expelled militants. That organization became one of the foundations of the RGO, which the KPD established in December 1929. By 1930 the RGO was described as a “red class trade union.” It attempted to conduct cross-union campaigns and to establish communist structures in important industrial sectors. Its principal areas of concentration included metalworking, mining, and construction. These organizations remained small, however, and never represented more than a marginal share of the workforce. The RGO’s reported membership reached about 250,000 in 1932, but the figure was disputed because the organization counted admissions without fully accounting for attrition. Unemployment also affected more than half of its members, making sustained workplace organization difficult. The KPD revised its trade-union policy in 1931 after losing influence through resignations and expulsions. Rather than relying exclusively on separate unions, communists were directed to work within the ADGB and other established organizations while developing “red associations” as more explicitly communist bodies. This made the RGO function increasingly as a party-directed opposition or front organization instead of an independent union movement. Its leading figures were generally selected through the KPD’s central trade-union apparatus rather than elected at regular union meetings. The Berlin transport strike of 1932 was the RGO’s most prominent public intervention. The organization supported a wildcat action against the Berlin Transportation Company after wage reductions and cooperated with the NSBO, the Nazi labor organization. The episode demonstrated the RGO’s willingness to oppose Social Democratic union leaders even when cooperation with an organization of the far right was involved. It also illustrated how the KPD’s ultra-left strategy could undermine broader labor solidarity. The Nazi dictatorship destroyed the legal environment in which all independent unions operated. On 2 May 1933, the SS and SA seized the offices of the ADGB and its member organizations. The RGO avoided immediate public dissolution by moving underground, but its clandestine structures were subject to systematic repression. By 1935 the Nazi authorities had crushed the organization. The RGO did not re-emerge as a significant postwar institution. East Germany instead established the Free German Trade Union Federation as a unified communist-led trade-union structure. During the 1970s, Maoist organizations in West Germany, including the Communist Party of Germany (Structural Organization) and the KPD/Marxist–Leninist, attempted to revive the RGO concept. These efforts had little practical success and did not recreate the influence or organizational role claimed by the original Weimar-era organization.
