Metalworkers’ union Numsa has threatened to take its mother body, Cosatu, to court for dragging its feet in convening a special conference. Numsa general secretary Irvin Jim told journalists on the sidelines of its four-day special conference in Boksburg that Cosatu was violating its own constitution in respect of how such conferences were called. “The constitution says if one-third of unions call for a special conference, it should be held, but now this morning (Cosatu president S’dumo Dlamini) said they should agree on the agenda first,” he said. He added Numsa would not rule out going to court to have Cosatu’s constitution enforced in this regard. Numsa is in the process of deciding whether it should remain in Cosatu or split. The decision will be announced at its plenary tomorrow morning. Numsa and eight other unions have called on Cosatu to have a special conference following the suspension of general secretary Zwelinzima Vavi when it surfaced that he had sex with a woman he had appointed to work for the federation. Numsa has openly vowed to support Vavi, claiming he was suspended for political reasons.
