By 1959 it was the only entity representing nationalist aspirations in Aden and it used its leverage to boycott elections as the main grouping of the People's Union.
[2] On 30 November 1967 the State of Aden became part of the independent People's Democratic Republic of Yemen, also known as South Yemen, and the ATUC became the main trade union of that state.
When South Yemen united with the Yemen Arab Republic, also known as North Yemen, on 22 May 1990, the Aden Trade Union Congress merged with the General Confederation of Workers' Trade Unions in order to form the Yemeni Confederation of Labor Unions.
[3] The ATUC was affiliated to the World Federation of Trade Unions.
