42 hours in Switzerland is IMHO a lie. I’ve seen and experienced tech and pharma setting expectations so high that people have to work at least 50-60 hours.
Don't you have anything like the Working Time Directive? I know Switzerland is not an EU member but then neither is Norway but we adhere to it as part of the obligations that we have regarding access to the Single Market.
Don't forget the commute either. Suddenly you're clocking in 12h days without even noticing.
