Guys,
Something more to consider before making decision to go to Switzerland or not is rules for taxations.
They are different in every canton, even in every community.
General pattern is, the places with cheaper accomodation prices have much higher tax rates and vice versa. Attention going somwhere outside to rent appartment/house does not mean saving the money, they will take it is just a question is it going to be taken by taxex or high rent.
Be firm/hard when negotiating with Skyguide,it works, almost each emplyee in Skayguide has different contract/qonditions, it is realy like on the market. My impresion is that they prefere cheap labour even if it means a bit less quality.
Of course it depends where you come from and what salary you have at the moment but due to high living costs I would advice you do not accept figurs lower than 160.000, everything below that means you will have to live very carefully your dayly life in Switzerland and you will not save much.
