Trade Union Rights in Switzerland

Freedom of Association

Article 28 of the Federal Constitution guarantees the right to organise in unions and to conduct collective action. Employees can join or not join a union as they choose, neither is compulsory. Employers cannot dismiss, demote or otherwise disadvantage an employee for union membership or union activities. Such retaliation is wrongful dismissal (Art. 336 CO), entitling the employee to compensation of up to 6 months' salary. Union representatives exercising their mandate have additional temporary protection during their mandate period.

Main Swiss Unions and Their Role

Key unions: Unia (~180,000 members, construction, industry, retail, hospitality), Syna (services, healthcare, food industry), KV Schweiz (commercial and administrative sector), VPOD (public sector), SGB (Swiss Trade Union Confederation, umbrella body for multiple unions). Unions negotiate Gesamtarbeitsverträge (GAV) with employer associations, setting sector-wide minimum standards. The Travail.Suisse federation groups the Christian and independent unions.

Strikes and Collective Action

The right to strike is constitutionally protected (Art. 28(3) BV) but subject to conditions: the strike must concern employment relations (not political issues), there must be no current peace obligation from a GAV, all other means (negotiation, mediation) must have been exhausted, and it must be proportionate. Switzerland has one of Europe's lowest strike rates, the tradition of social partnership and GAV peace obligations keep disputes at the negotiating table. Political or solidarity strikes are not constitutionally protected.

Context on the Swiss job market helps frame any career decision in Switzerland. Our gross-to-net salary guide shows what Swiss gross salaries look like after AVS, LPP and tax deductions. The salary negotiation guide covers how to use market data in offer discussions and which arguments work with Swiss recruiters. Our guide to working in Switzerland as a foreigner covers entry conditions, permit categories and practical relocation steps. The work permit guide explains B, C, G and L permit categories and processing timelines. For cross-sector salary benchmarks, the Switzerland salary guide covers all major roles and cities.

Frequently Asked Questions

Can I be dismissed for joining a union in Switzerland?

No. Dismissal for union membership or activities is explicitly wrongful under Art. 336 CO and entitles you to compensation of up to 6 months' salary. Freedom of association is constitutionally guaranteed.

Does a union membership benefit me even if my employer is not in a GAV?

Yes. Unions provide free legal advice for members, support in employment disputes, access to group insurance rates, and representation in individual claims. Even outside a GAV context, union membership offers personal protection.

What is the difference between a Swiss union and a German Betriebsrat?

A union (Gewerkschaft) is an external organisation that negotiates on behalf of workers across an industry. A Betriebsrat (works council) is an internal employee body within a specific company. Switzerland has unions but no mandatory works councils, the closest equivalent is the voluntary Arbeitnehmervertretung under the MWG.

What is the 13th month salary in Switzerland?

The 13th month salary in Switzerland refers to an additional monthly salary paid once a year, typically in December. It is included in annual salary benchmarks as standard: when a Swiss employer quotes CHF 120,000 per year, this normally means 13 monthly payments of approximately CHF 9,231 each, not 12 payments of CHF 10,000. The 13th month is governed by the employment contract or collective agreement (GAV), not by statute. It is subject to social contributions (AHV/ALV) and income tax. Always clarify with a prospective employer whether a quoted annual figure includes or excludes the 13th month.

How do Swiss notice periods work for employment contracts?

Under Swiss law (Code of Obligations, Art. 335c), notice periods during probation (default 1 month, up to 3 months by agreement) are 7 days. After probation, statutory notice periods are: 1 month during the first year, 2 months in years 2 to 9, and 3 months from year 10 onwards. Notice must be given in writing by end of calendar month (or end of the agreed notice period month). Contractual or GAV notice periods can be longer but cannot be shorter than statutory minimums. Protected periods exist (illness, accident, pregnancy) during which termination is suspended or prohibited.
