Just a bit of info for you. Block time currently 70-80ish hrs a month. Rostering, well they have just implemented a new 'agreement' which means you can be scheduled for 2 blocks of 2 days off per month, a maximum of 18 of these two day blocks can be allocated in any year. For example a 5-2-4-2-5 is possible. A guaranteed block of 4 consecutive days will be granted in every month. A fixed rosta similar to the UK would obviously be welcomed , as it stands you are informed of your monthly duties on the 20th day of the preceding month. It makes planning rather difficult!
Upgrading time..another contentious issue. They have just implemented a change in upgrade policy from FO to SFO from 1500 hrs (still the case in the UK) to 3000 factored hrs in Switzerland. Meaning a two year or more delay in many cases to some pilots just short of 1500 hrs. These changes were all implemented by management disregarding the current terms and conditions, and despite obvious opposition from the Pilots.
On a plus side your are paid in Swiss Francs, which at the moment is very strong against the UK pound, how long that will last is anyones guess.
