THE Zimbabwe Diamond and Allied Minerals Workers Union has appealed to the government to come to the rescue of more than 2 000 RioZim Limited workers who have gone for five months without pay. According to the Union, the Rio Zim workers’ desperate situation now warranted the intervention of the government. In a letter addressed to Public Service, Labour and Social Welfare minister Edgar Moyo, the union decried the sorry state that employees at the Zimbabwe Stock Exchange-listed firm find themselves in.
