In 1986 a British-owned company BTR (British Tyre and Rubber) dismissed its entire workforce. The workers had gone on strike in response to the company’s refusal to recognise their union NUMSA (National Union of Metalworkers). The strike was the longest-running dispute in South African history and the workers won support from trade unionists all over the world, including Britain. In the picture supporters are picketing the company’s London headquarters after taking part in a sit-down protest inside the building.
