@ TBSC
you are right, the problem is that in Wizzair, there are a lot of expats, and with Wizzair salary it's not easy to manage a family in your home country with maybe a house to pay and all the rest, and at the same time live and commute int the country where you work, with no sick leave in case something happened and no retirement contributions, and in the meantime try to save some money for the future.
This is the big picture, but as I said earlier, when you join you know the deal, take to leave it. If wizzair would have a better salary the rate of leaving was completely different, because apart that, it is a great place to stay.
