May 1 in Switzerland is a legislative curiosity, reflecting cantonal sovereignty and the intricacies of the Swiss federal system. Unlike many neighbouring countries, where Labour Day is a national holiday applied uniformly, the Confederation recognises only one federal public holiday: 1 August. For all other dates, responsibility lies with the cantons, creating a regulatory patchwork in which the status of May 1 can change dramatically from one cantonal border to the next. That disparity is not only geographic: it is also sector-specific, insofar as the nature of your employment contract may determine whether you will spend the day on a construction site or on leave.

Under the current setup, eight cantons have chosen to treat May 1 entirely as a Sunday within the meaning of the Federal Employment Act: Jura, Neuchâtel, Ticino, Zurich, Schaffhausen, Thurgau, Basel-Stadt and Basel-Landschaft. In these regions, economic activity almost comes to a standstill: shops close their doors and offices are empty. By contrast, in much of central and French-speaking Switzerland, such as Fribourg or Valais, the day remains a normal working day, even if some local customs allow work to stop at midday; in the cantons of Aargau and Solothurn, a half-day holiday is the intermediate compromise. Yet this cantonal mosaic has one major sectoral exception: even where May 1 is by no means a public holiday for the general population, construction sites are often deserted. This peculiarity stems from the national collective agreement for the main construction sector, a collective contract negotiated between trade unions and employers’ associations, whose provisions were extended by the Federal Council, making them binding on all companies in the sector, whether or not they are members of the employers’ association. That agreement enshrines May 1 as a paid day off for workers in structural construction, a major contractual exception that allows them to mark the day despite the absence of any cantonal legal recognition.

Geneva is probably the most complex case and regularly sparks lively debate. Officially, May 1 is not a public holiday there for the private sector, and yet the cantonal and municipal administrations are closed. The state relies on its status as an employer to justify this arrangement: much like a company granting an additional day off to its staff, it concluded an agreement with the inter-union coalition in the public sector, signed in 1985 and effective from 1986, whose provisions were incorporated into staff regulations, gradually turning May 1 into a full day off for state employees. This practice nevertheless creates a striking divide: while public counters are shut, employees in retail, hospitality and private services must still report to work. The state cannot impose the day across the entire private sector without a legislative change, which would run up against opposition from business circles that fear an additional day off would hurt competitiveness, especially in a canton where the Geneva Fast already applies by law to all employers, public and private alike. This privilege for civil servants, often seen as unfair by private-sector employees, remains deeply rooted in administrative practice and illustrates a constant feature of the Swiss model: in Switzerland, the right to rest depends less on national law than on geography, industry, or whether the employer is public or private.
