An interesting comparison can be made between the proposed KUL 744F salary of US$43,200 and the year 1 Syd Freighter salary of US$44,200.
Clearly this extra $1000 is valuable for it prevents your "colleagues" like Tom Tipper from describing you as "cheap foreign labour" or thepenguin warning that you are, "d-scales and undermining our jobs" or Fatbastard from exhorting, "my how our standards fall".
Every Syd 200F FO must grateful to Santa Ron for the extra grand, otherwise indeepsht will be justified in referring to you as a scab (in the politest of ways) and some very brave, but anonymous, hero will warn you that, "Fifteen hours in a -400...is a mighty uncomfortable place.. stay away.."
I remain unconvinced that had the company set up a 744F base in Syd on the same pay as the KUL base, this would have been an issue attracting such venom. I therefore wonder what the real issue here is?
