Your attitude suggests that you have grown up with the dangerous idea that the world owes you something: Freedom from age discrimination. A right to a job in a foreign country. A reward for your personal expense and sacrifice in becoming a pilot. Recognition of your A330 flying experience!
. . . It may help to settle your nerves if you would just lower your lofty expectations when pursuing employment in a third world country.
Accept the fact that you will be a second class citizen in the sand box; a guest worker with
no rights. Your employment contract and your rosters will only be pacifiers. . . . Completely meaningless and uneforceable by any expat in any court of law in any country in the middle east or asia.
Your supreme choice is to accept the working conditions, or not to accept the working conditions.
