SAFRICA-POLITICS-LABOUR-MAY1-UNION

Expelled Secretary General of Congress of South African Trade Unions (COSATU) Zwelinzima Vavi addresses a crowd of National Union of Metalworkers of South Africa (NUMSA) members and supporters during a May Day rally organized by a new United Front South African labour movement at Tembisa stadium on May 1, 2016 in Tembisa. Vavi was expelled from Cosatu in March 2015 for bringing it into disrepute and causing divisions by speaking out against the ANC governments policies and saying it had failed workers. He had since launched a new union federation to rival Cosatu. / AFP / JOHN WESSELS (Photo credit should read JOHN WESSELS/AFP via Getty Images)
