Is a lunch break included here? In Germany it’s the norm to work 40h, but (are obliged to) spend an additional 30 minutes there for lunch. So you’re at work for 42,5h but only get paid for 40.

There’s no such thing as a normalized workweek here in Switzerland. Most have 40-42h. The average are ~41h (edit: it seems that number is a few years old and it’s now just shy of 40h - but it’s too late in the evening to dig deeper). But yea, in certain jobs/industries, it can also be considerable more.
