It makes total sense. There is a requirement in Portugal for a limited number of pilots with around 6 crews per aircraft. It is a truly dreadful contract, dreamed up by the Group Ops Director himself, and is Ryanair in all but name. There will always be people willing to take it from outside, and a handful of people inside desperate enough to take the deal due to family circumstances, Portuguese relatives etc. It is bad news, but there you have it.
