The South African mining union, AMCU, that recently organized a successful industry-wide strike is facing deregistration. The labor registrar has stated that the union is “not a genuine trade union,” because it is not “function[ing] in terms of its constitution.” This decision comes just before the union prepares to enter wage talks in the platinum-industry. If the union is removed from the register, it can still organize strikes but companies would be allowed to forgo giving the union its fees.
