Well, I don't see what's wrong with giving people from eastern Europe jobs.
With Ryanair, it originated in the early 90's when they needed pilots to fly the BAC 1-11. These aircraft were taken over from Tarom, so they subsequently hired Romanian pilots. They turned out to be very good workers, so why not stick with them?
As long as they have the right to work in Europe, anyone can apply, including yourselves, so what is there to bitch about?
