Failed promises
You ask about pension etc... At interview I was promised health cover, loss of licence, shares and holidays, none of which in the end did I get. Excuses and lack of communication is one of the biggest problems Vueling have. The flying standards of both Captains and First officers were good and I never felt that the person sat next to me should not be there. If you are still considering joining and can afford to obtain you own type rating, do this, you can then gain sufficient experience in quite a short time to consider moving elsewhere if you feel the need too. Perhaps the top management will see the light and increase everyones terms and conditions? This is the only way that they will keep pilots!
