Qantas ground service workers are set to vote on industrial action. NewsWire / Dan PeledQantas ground service workers are set to vote on industrial action. On Wednesday evening, the Transport Workers Union filed a Protection Action Ballot, giving members the right to vote on industrial action. It comes following a bitter dispute over the outsourcing of 1800 ground workers, which the TWU says has impacted the pay, safety and working conditions of QGS-rostered workers. “There is no immediate risk of industrial action from this work group,” a spokesman said.
