African Trade Union Congress Following the split in the African nationalist movement in 1963, which led to the separation of the Zimbabwe African National Union (ZANU) from the Zimbabwe African People's Union (ZAPU), the ATUC became aligned with ZANU. The ATUC was affiliated with the African Trade Union Confederation. The ATUC was reported to have nine affiliated unions during the mid-1960s, with a total membership of 29,198 (36% of all trade union members in the country). The largest single affiliated union was the Railway African Workers' Union (RAWU), which had approximately 16,000 members. In 1981 ATUC merged into the Zimbabwe Congress of Trade Unions.
