Thanks so much for all this information, I've just read through the posts and it's really useful. Can someone just please confirm that I have this right please?

I have a UK passport and have been offered a job in Lausanne. All I need to do is register at the cantonial office within 8 days of arrival with my job offer and a copy of my passport to automatically get a residence permit. I don't need HR to get me a work permit etc. I can just do this myself when I arrive. Is it really that easy??
