Rio Tinto is replacing workers with driverless trucks at its Pilbara iron ore operations in Western Australia.

LMN member group Partizans notes that in the past, Rio Tinto seemed to favour eliminating workers by having them shot: Sir Auckland Geddes, Rio Tinto chairman, said to shareholders at its 1937 London AGM: “Since the [Rio Tinto] mining region [in Andalusia]  was occupied by General Franco’s forces, there have been no further labour problems…Miners found guilty of troublemaking are court-martialled and shot” [“Plunder!”, published byPartizans, London and Christchurch, 1991, page 8].
