At Fed Group, we see it every week: candidates arrive at interviews with a miscalculated notice period, a letter sent too late, or no understanding of the impact on their unemployment rights. Resigning in Switzerland is straightforward in theory — a unilateral act that does not even require a reason. In practice, a timing error costs a month's salary. Here is how to get it right.
The Swiss legal framework: what the Code of Obligations says
Under Swiss law, resignation is governed by articles 335 to 335c of the Code of Obligations (CO). A few fundamental principles that many employees are unaware of.
First, no specific form is required by law. An oral resignation, by email or even by text message, is legally valid — unless the employment contract or the applicable CBA requires written form. In practice, never do this. Without a written record, you have no proof of the date of receipt, and it is this date that triggers the notice period.
Second, you are under no obligation to justify your resignation. If your employer asks why, you may answer — but you are not required to. Art. 335 para. 2 CO simply provides that the party giving notice may be asked to state the reasons in writing. This is not a condition of validity.
Third, resignation is irrevocable upon receipt. Once your employer has read your letter, you cannot withdraw it without their agreement.
Notice periods: the table you must check before writing anything
This is where 90% of errors occur. The notice period depends on your length of service and runs to the end of a calendar month — unless the contract provides otherwise.
| Situation | Notice period | Legal basis |
|---|---|---|
| Probationary period (max. 3 months) | 7 calendar days | Art. 335b CO |
| 1st year of service | 1 month to the end of a month | Art. 335c para. 1 CO |
| 2nd to 9th year of service | 2 months to the end of a month | Art. 335c para. 1 CO |
| From the 10th year of service | 3 months to the end of a month | Art. 335c para. 1 CO |
These periods may be modified by written agreement, standard employment contract or CBA. However, a period shorter than one month may only be set by a CBA, and only for the first year of service.
Worked example: when to submit your letter to leave on 30 June
Sophie, 34, has worked for 4 years at a fiduciary firm in Lausanne. Her contract contains no specific provisions on the notice period. She wants her last working day to be 30 June 2026.
Her length of service places her in the 2–9 year bracket: 2 months' notice to the end of a month. Her letter must therefore be received by the employer no later than 30 April 2026 for the contract to end on 30 June.
If the letter arrives on 2 May? The deadline shifts: the contract then ends on 31 July 2026. One extra month — and one month's salary at stake if Sophie has already signed elsewhere with a start date of 1 July. We see this type of error regularly among our candidates. A single day's delay can disrupt the entire transition.
Resignation letter template standard Swiss version
Below is a template compliant with Swiss law, sober and professional. Adapt the elements in square brackets.
[First name Last name] [Address] [Postcode City]
[Company name] [Department / For the attention of Mr/Ms X] [Address] [Postcode City]
[City], [date]
Subject: Termination of my employment contract
Dear Sir/Madam,
I hereby inform you of my decision to terminate my employment contract in the position of [job title], entered into on [start date of contract].
In accordance with the notice period of [duration] provided for by [my employment contract / art. 335c CO / the applicable CBA], my employment will end on [end date, last day of the month].
I remain at your disposal to organise the handover of my files and to ensure a smooth transition.
Yours faithfully,
[Handwritten signature] [First name Last name]
A few key points about this template. No reason given: you do not need one. No emotion: neither reproaches, nor apologies, nor excessive thanks. A resignation letter is not a farewell letter — it is a legal document. If you wish to thank your employer, do so during the exit interview, not in a document that could end up in a file.
Resignation during the probationary period: what changes
During the probationary period — which corresponds to the first month of employment unless a longer period is agreed in writing (maximum 3 months) — the notice period is reduced to 7 calendar days. Termination may take effect on any day, not necessarily at the end of a month.
Important: during the probationary period, protections against termination at an inopportune time (illness, pregnancy, military service) do not apply. This works both ways: the employer can dismiss you during sick leave, and you can resign even while incapacitated.
Practical example: Karim, an engineer, is hired on 1 March 2026 with a 3-month probationary period specified in the contract. On 15 April, he receives a better offer. He sends his resignation on 16 April. His contract ends on 23 April (7 days later). No need to wait until the end of the month.
Resignation and illness: a widely misunderstood point
In Switzerland, the employee who resigns does not benefit from the protections of art. 336c CO. These protections (suspension of the notice period in case of illness, pregnancy, military service) apply only when it is the employer who terminates the contract.
In other words, if you resign during sick leave, your resignation is perfectly valid and the notice period runs normally. Your sick leave does not suspend it. This is a fundamental difference from dismissal that many employees are unaware of.
Method of delivery: registered post, hand delivery or email?
The delivery method has a direct impact on the computation of your notice period. It is the date of receipt by the employer that counts, not the date of sending.
Registered post: the gold standard. The letter is deemed received on the first business day following the delivery attempt (even if the employer does not collect it from the post office). Allow 1 to 2 days between sending and receipt.
Hand delivery: perfectly valid. Have a copy signed with the date of receipt, or deliver the letter in the presence of a witness. This method is faster and gives you full control over the timing.
Email: legally valid unless the contract provides otherwise. But proof of receipt is weaker. If your employer is on holiday, the email is only considered received upon their return. We advise against this method except as a supplement to registered post.
Resignation and unemployment: the real financial consequences
This is the point that surprises our candidates the most. If you resign without having a new job secured, unemployment insurance considers that you caused your own unemployment. Consequence: a suspension of your benefits lasting 31 to 60 working days. In practice, the suspension typically falls between 30 and 40 days — roughly two calendar months without income.
After this suspension period, you receive 70% of your last salary (80% under certain conditions, notably if you have dependent children).
Our position is clear: never resign without having signed a new contract, or at the very least without having built a financial reserve of at least 3 months. If you are considering a move, start by carrying out a self-assessment and launch your search in parallel.
Legitimate reasons that may reduce or eliminate the suspension include documented harassment, repeated non-payment of salary, medically certified health risks, or relocation imposed by family circumstances. But the burden of proof lies with you, and the assessment remains at the discretion of the unemployment office (ORP) and your unemployment fund.
Documents to collect on your last day
At the end of your employment relationship, your employer must provide several documents. Do not leave without checking that you have everything.
The work certificate (art. 330a CO) is the most important document. It must be complete (qualified reference): it states the duration of employment, the nature of the position, your responsibilities and an assessment of your work and conduct. You are entitled to it, and the employer is obliged to produce it.
The employer's attestation for the unemployment fund is essential if you register with the ORP. The employer must provide it within 2 weeks.
The final statement (solde de tout compte): pro-rata salary, untaken holiday, pro-rata 13th month salary, overtime. Check every line. To negotiate the transition effectively, you need to know your rights precisely.
FAQ
Can you resign by email in Switzerland?
Yes, unless your contract or the applicable CBA requires written form. Swiss law imposes no particular form for the termination of an employment contract. However, for evidential purposes, registered post remains the safest method.
What happens if my employer refuses my resignation?
They cannot refuse it. Resignation is a unilateral act that takes effect upon receipt, regardless of the employer's wishes. They may, however, require you to serve your notice period — which you are obliged to do.
Can my employer release me immediately after I resign?
Yes. They can release you from your obligation to work during the notice period. But they must continue to pay you until the end of the contract. This is a release from the duty to work, not an early termination of the contract.
Do I have to reimburse training funded by my employer if I resign?
Only if a reimbursement clause appears in your contract and the specified conditions are met (minimum post-training commitment period, degressive amount). Check your contract before submitting your letter.
