The really sad story is, that whilst a pilot may be worth AED 5000 for working on a day off, plenty in EK are evidently willing to do it for much, much less. Since that's the case, it would be utterly foolish of management to offer anything more, than what people are willing to work for. If that figure is AED 600, well, don't blame management - blame your colleagues for selling themselves cheap.
Pilots have always been a pilot's worst enemy. Self-Sponsored training, self-sponsored type-rating, P2F, one-man companies, ME3 labour practices, airlines operating without a unionised workforce; the list is long, almost endless.
