The overwhelming numbers of QF employees would condemn these threats. Don't tar all Qantas employees and union embers with the same brush. A bit of perspective from all sides would be a great thing.
That includes some empathy from Qantas that the games they are playing industrially involve individual people- many of whom fear greatly for their livelihood. Whilst no reasonable person would condone these threats, AJ et al are seriously ignorant if they don't think that their industrial tactics also don't look like bullying and intimidation to front line staff.
