Sorry for being a bit cynical about this but Ryanair is all about control. The main reason to go all round the world to acquire pilots is to dilute the strength of pilot power. They find it much easier to get what they want i.e. lower pay and conditions.
For instance as they are doing at the moment, employing pilots from Brazil, the pay deal they will have offered will look fantastic to them, so they will be no problem to them when the next pay round starts (dispute). I might add I do question the actions of Ryanair some of these pilots are direct entry left seat, I am sure some of them have NEVER SEEN SNOW!
