Qantas chief Alan Joyce has received a death threat, managers have been sent menacing letters and strike-breaking workers have been bullied by striking union members according to the airline. The Daily Telegraph newspaper reported one letter threatening Joyce that the unions will fight on: “Qantas is our airline, started & staffed by Australians, not foreign filth like you,” it read. The paper also said senior Qantas staff had had their car windows smashed and houses damaged after refusing to strike. Transport Workers Union (TWU) national secretary Tony Sheldon has confirmed that union members too had received threatening emails saying: "You lazy dirty bunch of scabs. Pulling strikes at this time of year has finally made all TWU members the most hated in the country." Australian Licensed Aircraft Engineers Association (ALAEA) federal secretary Steve Purvinas has deplored the threatening behaviour and said all incidences should be reported to the police.
