Australian Workers Union chief Paul Howes has demanded more Federal Government support for the steel industry and claims manufacturing is facing its worst crisis since the Great Depression.Responding to news BlueScope will shed 1000 jobs, Mr Howes called for a crackdown on manipulation of the Chinese Yuan, a more robust anti-dumping system and stronger domestic procurement policies for the resources sector.‘‘Today’s announcement is devastating for the families of more than 1400 workers who will be feeling the trauma and distress that comes with the loss of a secure income,’’ he said.
