The Austrian Trade Union Federation or Austrian Federation of Trade Unions (de: Österreichischer Gewerkschaftsbund, abbreviated OeGB or ÖGB) is a labour union of employees. It is constituted as an association and is subdivided into seven smaller affiliated trade unions. Each union is traditionally dominated by a certain political faction, with the strongest faction in the ÖGB as a whole traditionally being the social democratic one (Fraktion Sozialdemokratischer GewerkschafterInnen), which is known for its close contacts to Austria's Social Democratic Party (SPÖ); chairmen of the ÖGB have often also been influential SPÖ members.[1]
