It's a shame that occurred teresa. Perhaps it was a response to being told that the Impulse/ Jetstar Pilot Council had rejected AIPA overtures when we bought Impulse.
Some other 'facts' from a bit earlier than your example- these from a time before J* started operating heavy metal overseas and were flying 717s in QantasLink uniforms. Avoiding looking you in the eye or looking away once eye contact was made when in close proximity in the terminal. Being ignored when you subsequently said 'hello'. Getting grunts in response to questions about their day when standing beside them getting coffee.
It was an unpleasant time for crews on both side of the fence. I'll note that since that time J* has probably tripled (or more) in size and QF has added another 400-500 pilots and so for many crew in both airlines they have no frame of reference to this sort of stuff.
Perhaps we should just focus on what unites us rather than what divides us.
