The Workers' Union of Ireland (WUI), later the Federated Workers' Union of Ireland, was an Irish trade union formed in 1924. In 1990, it merged with the Irish Transport and General Workers Union to form the Services, Industrial, Professional and Technical Union (SIPTU).
The WUI was formed in 1924 as a consequence of the clashes between James Larkin and the incumbent leadership of the ITGWU, subsequent to his 1923 release from Sing Sing and return to Ireland in April 1923. Larkin, still officially general secretary of the ITGWU, clashed bitterly with William O'Brien, who had taken leadership of the ITGWU, the Irish Labour Party and the Irish Trades Union Congress.
During Larkin's absence at the 1924 Comintern congress (and possibly against his wishes), his brother Peter led their supporters out of the ITGWU, forming the WUI. The new union quickly grew, gaining the allegiance of about two thirds of the Dublin membership of the ITGWU and of a smaller number of rural members. It affiliated to the pro-Soviet Red International of Labour Unions, but during the 1930s gradually entered the mainstream of the Irish trade union movement, being admitted to the Dublin Trades Council in 1936 (although the Irish Trades Union Congress would not accept its membership application until 1945).
In 1941 a new trade union bill was published by the Government. Inspired by an internal trade union restructuring proposal by O'Brien, it was viewed as a threat by the smaller general unions and the Irish branches of British unions (known as the 'amalgamated unions'). Larkin and the WUI played a leading role in the unsuccessful campaign against the bill.
After Big Jim Larkin's 1947 death, his son James Larkin Jnr became general secretary, and continued to preside over a gradual expansion of the WUI, including amalgamations with a number of other unions. In 1979, the Federation of Rural Workers merged in, and the union renamed itself as the "Federated Workers' Union of Ireland".
