South African Trades Union Council Wikipedia
The South African Trades Union Council was established in 1925 as a result of a special congress after the collapse of the South African Industrial Federation called by the Minister of Labour, Colonel Cresswell. All the affiliated unions were registered under the Industrial Conciliation Act 1924 and represented white workers. It merged with the Cape Federation of Labour Unions in 1930, forming the South African Trades and Labour Council.
The secretary was Bill Andrews, the first General Secretary of the Communist Party of South Africa.
