A wave of strikes began in Durban in early January 1973 and spread across many workplaces over the following months. The actions were driven mainly by low wages and harsh working conditions, and they involved tens of thousands of African workers. The strike wave helped restart independent Black trade union organizing on a larger scale after years of repression.
As new factory-based unions grew after the 1973 strike wave, organizers created the Trade Union Advisory Co-ordinating Council (TUACC) as a loose coordinating body in early 1974. TUACC encouraged democratic shop-floor structures and aimed to organize workers regardless of race. This helped turn local struggles into a more connected labor movement.
The Federation of South African Trade Unions (FOSATU) was officially launched on 20 April 1979 after a founding congress earlier that month. It brought together important unions that had emerged from the 1973 strike wave and emphasized non-racialism and strong shop-floor control. FOSATU became a major step toward building a national, coordinated labor movement opposed to apartheid.
The government appointed the Wiehahn Commission to review industrial relations amid growing labor unrest. Its first interim report was tabled in Parliament on 1 May 1979. The commission’s work opened the door to reforms that would later allow Black trade unions to gain legal recognition through registration, changing the terrain for union growth.
The Council of Unions of South Africa (CUSA) was formed on 14 September 1980 by unions that did not join FOSATU. CUSA reflected a different organizing tradition and was influenced by Black Consciousness currents. Its formation showed both the growth of labor activism and the strategic debates about unity, leadership, and political alignment.
The National Union of Mineworkers (NUM) was established on 4 December 1982 in Klerksdorp (now Matlosana). It organized Black mineworkers in a sector central to South Africa’s economy and apartheid labor controls. NUM’s rapid growth helped shift union power into mining and strengthened the push for a broader federation.
The United Democratic Front (UDF) was launched on 20 August 1983 in Mitchell’s Plain, Cape Town, bringing together hundreds of organizations. While not a trade union body, it helped connect workplace issues to community campaigns against apartheid laws and local authorities. This wider alliance created more space for coordinated mass action, including strikes and stayaways.
On 3 September 1984, protests in the Vaal Triangle against rent increases included a stayaway from work and school. Police violence and escalating resistance turned local grievances into a wider township uprising that spread. The period strengthened ties between community organizations and parts of the labor movement, encouraging broader “mass action” tactics.
After several years of unity discussions among anti-apartheid unions and federations, delegates met in late November 1985 to finalize a new federation. COSATU was officially established on 1 December 1985. It brought together major unions (including many from FOSATU and NUM) and presented a stronger, more unified labor front against apartheid repression and exploitation.
By its launch, COSATU united dozens of unions into a single national federation and quickly became a central hub for worker coordination. Its non-racial, democratic approach supported large-scale organizing across key industries. This consolidation increased unions’ bargaining strength and made labor a more influential part of the broader anti-apartheid movement.
During the nationwide State of Emergency in 1986, security forces detained and harassed many union activists, with reports that large numbers of detainees were linked to COSATU-affiliated unions. The repression aimed to disrupt the growing alliance between workplace organization and mass community protest. Even so, the period underscored that unions had become a major, organized force challenging apartheid by the mid-1980s.
On 5 October 1986, CUSA and AZACTU merged to form the National Council of Trade Unions (NACTU). This created another national federation alongside COSATU, reflecting enduring political and organizational differences within the labor movement. The merger clarified the main centers of union organization as repression intensified.
