THE National Union of Mineworkers warned on Thursday night that several thousand of its workers will strike on Friday. Late reports indicate that a number of smaller unions have settled the wage dispute with employers. The strike is expected to hit Anglo American Coal (AmCoal) which has nine collieries, and Ingwe. Also expected to be targeted by the strike is the Durban Roodepoort Deep group which has three operations in Hartebeesfontein, Blyvooruitzicht and Roodepoort.
