The decision of the National Union of Metalworkers of South Africa (NUMSA) to cut ties with the ruling African National Congress (ANC) has been badly analysed.
Comment has tended to focus on the possibility of a new political party in 2019, or whether suspended general secretary of the Congress of South African Trade Unions (COSATU) Zwelinzima Vavi will get his job back.
But the greater significance of the biggest trade union in the country throwing in its lot with a growing movement in opposition to the neoliberal order, and thus to the left of the ANC, is being missed.
