Ah yes we have some general contracts for whole sectors as well that ususally contain better conditions (called Gesamtarbeitsvertrag GAV).

My workplace, also IT, also gives 180 Swiss Franks a month to help with lunch (much appreciated in Zürich, shit’s expensive). There are some tax rules concerning workplaces either offering cafeterias or lunch subsidies. I believe 180 is the most they can give you before it counts as a separate form of income. I think this is common for office jobs, but I also don’t have hard numbers.
