QANTAS has dismissed industrial action by professional engineers as a scare tactic, saying work bans will not hurt operations or Easter travel plans.Members of the Association of Professional Engineers, Scientists and Managers Australia yesterday voted to extend overtime bans through the four-day break beginning tomorrow.The union, representing Qantas and Jetstar professional engineers, said it could not guarantee flights would run to schedule and apologised to travellers.But a Qantas group executive, David Epstein, said the union industrial action, which he said had been continuing since late last year, had not affected services. ”It has continually tried to undermine passenger confidence in Qantas including before the Christmas and New Year holidays,” he said.Union members voted for work bans due to concerns about the overnight and weekend assignment of Qantas managers to cover the positions of specialist senior professional engineers. A union industrial officer, Alison Rose, said: ”Qantas continues to bring in inexperienced workers to cover the roles of our specialist senior professional members.”AAP
