The Association of Mineworkers and Construction union in Africa just ended a five-month strike by signing a wage agreement that will last for three years. The violent strike resulted in at least nine deaths, halted production, and negative financial outcomes for the company. The AMCU went on strike in November following its refusal to approve of a wage agreement that the company had negotiated with other unions. As a result of the strike, employees will now receive greater wages and benefits.
