The Federation of Unions of South Africa (FEDUSA) is the second largest national trade union center in South Africa.
The federation was founded on 1 April 1997, when the Federation of South African Labour Unions merged with the Federation of Organisations Representing Civil Employees. Many affiliates of the Federation of Independent Trade Unions also joined. On founding, about 80% of its members were white-collar workers, and 70% were white.
The federation worked closely with the World Confederation of Labour, but did not affiliate. Instead, in 1998, it affiliated to the International Confederation of Free Trade Unions, and has continued membership of its successor, the International Trade Union Confederation (ITUC). In 2006, it began negotiating a merger with the rival National Council of Trade Unions. They formed an umbrella organisation, the South African Confederation of Trade Unions, in 2007, but it achieved little, and the two federations remained independent.
The federation has favoured negotiation over industrial action. In 2015, it advised its public sector affiliates to accept a pay rise lower than that offered, in order to reduce government expenditure. It has placed a strong focus on its union education programme. In 2019, its long-term general secretary was dismissed after being accused of corruption. By 2020, it claimed a membership of 700,000, although the ITUC quoted a figure of 500,000.
The following unions were listed as affiliates, as of 2021:
