I am clinical psychologist, looking for work at present. I live in Luzern, and am close to Zug. I have conversational German, but I really would have to work through English for the next year or so.

And that's the issue.

Could anyone help me with advice as to how one in my situation goes about finding employment? Are there organisations or people I could talk to, for English-speaking health service workers? I am off to drop in to Manpower, Adecco, Kelly, etc, but I know I will probably get blank, confused stares!

I know there must be a need for this sort of work, given the population of international workers in CH!

Try to search here, at least for the similar specializations, the procedure will be similar. Here is a similar thread.

While it is true there is a large number of international specialists, you will not work in an isolated scenario. I would invest all I have into learning at least one of the local languages, it will speed up your work placement.

Good luck.
