THE National Union of Metalworkers of South Africa (Numsa) is threatening to strike at Ferrometals and Columbus Steel near Middelburg, according to Stephen Nhlapho of Numsa. Nhlapo blames the potential industrial action on the firms’ refusal to address union concerns such as racism, failure to implement the Employment Equity Act, and planned job cuts. The target ot the strike is a joint venture between Highveld Steel, Samancor, and the Industrial Development Corporation.
