The Australian Construction, Forestry, Mining and Energy Union (CFMEU) said Tuesday that Rio Tinto’s redundancy package for its Blair Athol coal mine discriminates against union members. The mine, near Clermont in Central Queensland, is closing down in less than two months after almost 30 years of production. The announcement came after Rio pushed forward the closure date, slashed jobs at the nearby Clermont coal mine and closed its offices in Sydney.
