The National Union of Mineworkers (NUM) this week threatened strike action if the Anglo American corporation does not reverse its policy against providing anti-retroviral drugs to its workers. The multinational corporation earlier this year made headline-grabbing news when it announced that it would provide anti-retroviral treatment for its HIV-positive workers. Now the union says Anglo American is reneging on its promise. The corporation is denying that it made any promise either unconditionally or by implication.
