Notice period in Switzerland: how it works for employees
Swiss notice periods are among the most straightforward in Europe, but they have one critical peculiarity that catches many expat professionals off-guard: notice always runs to the end of a calendar month, not 30 days from the date of notification. Resign on the 15th of June with a 1-month notice period and your last day is July 31st, not July 15th. This single detail has derailed many planned start dates and created conflict with new employers expecting faster transitions. This guide clarifies all the rules.
Swiss notice periods are governed by the Code of Obligations (CO, Article 335c). The legal minimums are: 1 month in the first year of service, 2 months in years 2–9, and 3 months from year 10 onwards. These are minimums that can be extended by individual contract or collective labour agreement, but cannot be reduced below the statutory minimum (except during the trial period). A contract that specifies a 1-week notice after year 1 is legally invalid: the CO minimum applies.
- Year 1 (after trial period): 1 month notice, effective end of month.
- Years 2–9: 2 months notice, effective end of month.
- Year 10+: 3 months notice, effective end of month.
- Notice given on any day of the month takes effect at the END of the following (or second following) month.
- Notice can be given verbally but written notice is strongly recommended.
- Employer-paid gardening leave (leave of absence during notice) is legal and at employer's discretion.
- Pay in lieu of notice: possible but only by mutual agreement; employer cannot force immediate departure without paying full notice period.
How to calculate your last day
This is where Swiss notice differs from most other countries. If you hand in your resignation on June 15th:
- Year 1 (1-month notice): notice runs until end of July = last day July 31st.
- Years 2–9 (2-month notice): notice runs until end of August = last day August 31st.
- Year 10+ (3-month notice): notice runs until end of September = last day September 30th.
If you hand in notice on July 1st (first day of the month), the calculation is identical: notice starts at the end of that month, so a 1-month notice ends August 31st. Handing in notice on the first versus the last day of the month makes no difference to the effective end date.
Resignation process: practical steps
Swiss law allows oral resignation, but written resignation is strongly recommended: by registered letter (lettre recommandée / eingeschriebener Brief) to create a dated proof of delivery. Email is generally acceptable in practice but provides less legal certainty. Your resignation letter should state: your name, the date of notification, and the effective end date based on your notice period calculation. No reason is required: resignation is unconditional in Swiss law. You are not required to explain why you are leaving, and providing an explanation is purely optional.
Gardening leave (dispense de travail)
Swiss employers can place a resigning employee on gardening leave (dispense de travailler) during the notice period, releasing them from showing up for work while continuing to pay full salary until the end of the notice period. This is at the employer's discretion and cannot be forced by the employee. Gardening leave during resignation is common in finance, consulting, and tech roles where intellectual property or client confidentiality concerns make continued presence sensitive. If placed on gardening leave, you remain contractually bound until the end of the notice period: you cannot join a competitor (especially if a non-compete clause applies) before that date.
Pay in lieu of notice
If you want to leave faster than your notice period allows (for example, your new employer wants you to start in 2 weeks but your notice is 2 months), you can negotiate "pay in lieu of notice" with your current employer: they release you immediately in exchange for payment equal to the remaining notice period salary. This must be agreed by both parties; you cannot unilaterally leave before notice expires, and neither can the employer terminate you immediately without paying through the end of notice (except for cause, "licenciement immédiat" for serious misconduct). In practice, many Swiss employers will agree to an early release if the notice period payment is waived by the employee, meaning you leave early and neither party owes the other. This is negotiated case-by-case and not automatic.
Frequently asked questions
Can my employer refuse to accept my resignation in Switzerland?
No. Resignation is a unilateral act: you do not need the employer's agreement to terminate the contract. As long as you give the required notice in writing, the resignation is legally effective regardless of whether the employer "accepts" it.
What is the Certificat de Travail and when do I receive it?
The Certificat de Travail (work certificate) is a document summarising your role, duration, and performance that Swiss employers request from all applicants. Your employer is legally required to provide one upon request, even before you leave. It can be simple (dates and title only) or detailed (including a performance assessment): a detailed one is standard and much more useful for future applications.
Can I take annual leave during my notice period?
Yes, by mutual agreement. The employer cannot unilaterally assign all your remaining holidays to the notice period without your agreement (except if the notice period is long enough to reasonably accommodate the leave). If your leave cannot be taken during the notice period, you are entitled to financial compensation for unused days.
