dr. dre, "the evidence" will be texts, emails and recordings of conversations within HR to the effect that the KPI to be achieved by HR is 50% gender split in recruited pilot numbers. This information MAY be discovered in a lawsuit.
The way this comes about is Board level conversations: "Hey Bro, wouldn't it be good for our market positioning if we were hip, cool and LGBT friendly starting with pilots and cabin crew? And wouldn't that differentiate us from Qantas?". "Yeah man, and that would make us cool with all that diversity **** going down with government as well".
"OK HR Department, take us in that direction"......And shortly you will get a puff piece in the Fairfax press about a couple of girls (Sarah and Julie) piloting a Jetstar B737 with an "incidental" paragraph about their partners (Susan and Elizabeth) and how great everything is. It's called virtue signalling. HR KPI achieved!
If you are male, white and your intended employer is talking about "diversity" then don't bother applying for a job.
To put that another way, its worse. If you are LGBT you are employable in preference to a heterosexual white male.
