SOME 7,000 SOUTH AFRICAN MINERS RETURN TO WORK Some 7,000 black workers returned to work after staging one-day strikes at two mines on Monday, the National Union of Mineworkers and the companies that own the mines said. About 6,000 miners resumed work at the Grootvlei gold mine east of Johannesburg after protesting the transfer of colleagues to other jobs at the same mine, owners General Mining Union Corp Ltd <GENM.J> said. The union said about 1,000 mineworkers at a new coal facility owned by Anglo American Corp of South Africa Ltd <ANGL.J> also returned to their jobs on Tuesday. The workers at Anglo's Vaal Colliery south of Johannesburg had struck to protest the alleged refusal of officials of the South African homeland of Transkei to allow miners to attend a funeral in the homeland, a union spokesman said.
