How will the Euro crisis and global recession affect the job hunting opportunities in Switzerland? Are there companies you recommend talking to to find new doors to open in terms of job opportunities?

Very difficult.
Stick to your job if you have one.

Expanding companies in 2012...Aldi, ORP, that's about it

maybe a few less jobs, but companies are now looking to hire the lowest paid possible people that are willing to take this job as their last (unless tech companies) Switzerland will simply follow what the rest of the world has gone through....my opinion

Compared to EU countries surrounding Switzerland, the labour laws here are very week. Even big profitable Swiss companies are taking on the "Hire & Fire" syndrome, and very few people feel completely safe in their jobs. Switzerland is very much affected by world financial swings, the higher value Swiss Franc is causing a slow rise in Swiss unemployment.

According to the reports we use to receive (external consultants) with information about markets and so on... the expectations are not bad, but with one eye on what's going on in the world.

A personal experience, we submitted the budget a couple of weeks ago, and we received a message from the top, to cut some projects and hirings, or strongly justify them.

Labour laws here are flexible, and thats a good thing. Flexible is what you require to overcome tough times such as now. Its the reason why Switzerland has the lowest unemployment rate in Europe. Here companies have the ability to soften economic impacts, i.e. employers can ask for productivity gains and a cut in salary during these times. Unfortunately with the impact of a slowing Eurozone and global economy, Switzerland wont escape.

Bad, or maybe like this last few months.

However, even universities like ETH expect a cut on their budget and are reducing their staff.
