They are seeking equal pay for an equal service, I don't see why that's hard to understand.
As for the lounge access, it's extremely pleasant after a shift before pacing to relax in a clean and comfortable environment instead of the crew room or in the local coffee shop fighting for a seat. Just my two cents though.
That prehistoric notion of "if you don't like the conditions find another job" is quite behind the times. Budget airlines are budget airlines, but there's no such thing as a budget pilot.
I still can't fathom the decision to not give the same benifits (as Qantas) to this pilot group, consider qlink EFA and network get better.
