The Association of Mineworkers and Construction Union in South Africa submitted a request to strike to the South African labor court- this request has been rejected. The AMCU has been on strike since November, however, the union wanted to extend the strike- making it “industry wide.” The union is surprised that the request was denied, and intends to appeal the labor court's decision regarding secondary strike activity. Labor union judge, Connie Prinsloo, stated concerns that an industry-wide strike would threaten the South African economy.
