Insurance giant IAG is backpaying 19,000 current and former workers more than $21million after an intervention by the Fair Work Ombudsman. The company is the latest Australian corporate to be outed over worker underpayments in recent years and in addition to backpaying staff it will also fork out a $650,000 "contrition" payment. Fair Work Ombudsman Anna Booth says many of the underpaid workers were at the lower end of the pay scale at IAG.
