I heard about this here in Austria that Swiss laws are way more business friendly at less worker friendly than here, basically reaching at will employment.
It "at-will" in the sense that your employer doesn't need to justify firing you. But I wouldn' compare it to what they have in some states in the US.
However you still have at least 1 month notice, and often more depending on the industry and seniority. Here in Zürich the standard in tech seems to be 3 month (anecdata though).
Where it gets kinda business friendly is that if you are fired for an illegal reason, it's up to you to prove that you were instead of your employer having to prove he fired you for something reasonable. The settlements are also nothing that would deter a company to behave badly I guess.
There is also a good tradition of union-like structure in the professions that need it (the ones where one is easily replaceable basically) that give workers a nice protection and benefits. It's not like in France of course but it's far from the US, based on the stories I gleaned about on HN.
