As Alsacienne said, you are not obliged to live in Switzerland, a lot of EZS pilots are leaving in France around Geneva...
No expansion is forseen in short terms in EZS, maybe a temporary additionnal aircraft during summer (???).
On the upgrade front, there should be a few this year, around 5-6,and quite a lot of experienced SFO are already waiting so I doubt that a new entrant can expect a rapid upgrade, don't expect to pass in front of everyone and to upgrade quickly...
And on the contract side, from the 1st of January, every EZS pilot will have an EZS contract, no more contractor...
