Opposition leader Bill Shorten says he won't give union-backed Industry Super funds preferential treatment if he is successful at this year's federal election. Former Trade Unions Secretary Bill Kelty, an architect behind industry super, says the Labor leader has a duty to protect worker savings by standing up to underperforming funds. The Productivity Commission recently recommended regulators select a list of the top 10 performing super funds for new workers but Mr Kelty has instead suggested that the bottom 10 simply be abolished.
