He acted enthusiastically as General Secretary during the General Strike of 1926 and was confirmed in that position after it, without opposition, at the Trades Union Congress of September 1926. The defeat of the general strike proved a watershed for the trade unions, persuading most General Council leaders to abandon their previous syndicalist philosophy. With other leading figures, such as Ernest Bevin (1881–1951), Citrine helped change the face of British trade unionism. They took the unions from the path of class conflict rhetoric to pragmatic cooperation with employers and government in return for union recognition and industrial advances. It was said that they took the TUC 'from Trafalgar Square to Whitehall'.
