Employment Termination in Switzerland: Notice Periods, Protection (CO 336c) & Templates

Swiss employment law operates on the liberal foundation of freedom of dismissal: an indefinite employment relationship may generally be terminated by either party without having to demonstrate cause. However, the Swiss Code of Obligations (CO / OR) balances this flexibility with strict statutory notice periods, absolute protection periods against dismissal during illness or pregnancy (untimely dismissal under Art. 336c CO), and precise rules governing garden leave. Understand your legal rights, statutory obligations, and explore ready-to-use Swiss resignation letter templates.

1. The Core Principle: Freedom of Dismissal in Swiss Labor Law

Unlike several neighboring European jurisdictions where dismissal requires prior economic justification or statutory redundancy approvals, Switzerland enforces the principle of freedom of dismissal (Kündigungsfreiheit) established in Article 335(1) of the Swiss Code of Obligations (CO). Both employer and employee have the right to terminate an open-ended employment relationship by giving proper notice.

However, this fundamental freedom is bounded by two vital statutory protections:

Mandatory Written Justification Upon Request (Art. 335(2) CO): The terminating party does not need to provide a reason upfront. However, if the recipient formally requests a statement of reasons in writing, the employer or employee must provide a truthful written justification.
Prohibition of Abusive Dismissal (Art. 336 CO): A termination rooted in personal attributes (age, nationality, sexual orientation, union affiliation, or religious faith) or carried out to thwart the employee from asserting lawful wage claims is legally categorized as abusive (missbräuchliche Kündigung). While the termination remains valid, the employer may be ordered by a Swiss labor court to pay indemnity compensation of up to 6 months' gross salary.

2. Statutory Notice Periods in Switzerland (Art. 335b & 335c CO)

Unless deviating terms are agreed upon in writing within an individual employment contract or an applicable Collective Labor Agreement (CLA / GAV), the statutory notice periods set out in the Swiss Code of Obligations apply automatically:

Length of Service	Statutory Notice (CO)	Effective End Date	Swiss Market Standards
Probation Period (1–3 months)	7 calendar days	To any calendar day	Statutory default is 1 month; extendable by written agreement up to a maximum of 3 months (Art. 335b CO).
1st year of service	1 month	End of a calendar month	Applies from the 4th month up to the end of the 12th completed month.
2nd to 9th year of service	2 months	End of a calendar month	The most widespread baseline in the Swiss corporate landscape.
10th year of service onwards	3 months	End of a calendar month	Executive contracts typically stipulate 3 to 6 months by contractual clause.

Mandatory Parity Rule (Art. 335a CO): Notice periods must be equal for both parties. If a contract provides for asymmetrical terms (e.g., 1 month for the employer and 3 months for the employee), the longer period (3 months) applies automatically to both parties under federal law.

3. Protection Periods: Dismissal at an Inopportune Juncture (Art. 336c CO)

To protect employees from sudden distress during non-culpable incapacity, Swiss federal law establishes absolute protection periods (Sperrfristen) during which the employer cannot lawfully terminate employment:

Illness & Accident (Art. 336c(1)(b) CO)

1st year of service: 30 calendar days of protection.
2nd to 5th year: 90 calendar days of protection.
6th year onwards: 180 calendar days of protection.

Pregnancy & Maternity (Art. 336c(1)(c) CO)

Throughout the entire term of pregnancy.
During the 16 weeks following childbirth.
Any dismissal served by the employer during this protected timeframe is void ab initio.

Military & Civil Defense Service (lit. a)

For the entire duration of compulsory Swiss service.
If service lasts longer than 11 days: protection extends to 4 weeks before and 4 weeks after.

Critical Legal Distinction: Two Distinct Scenarios

Scenario A: Notice is served DURING the protection period.
The notice of termination is null and void (devoid of legal effect). The employer must re-issue notice from scratch after the employee fully recovers or the statutory protection window expires.

Scenario B: Notice was served BEFORE the employee became ill.
The termination remains valid, but the notice period is suspended during the duration of certified medical incapacity (up to the 30, 90, or 180-day cap). Once the employee is certified fit, the remaining balance of the notice period resumes, and the effective termination date is automatically extended to the end of the subsequent calendar month.

4. The Receipt Theory (Empfangstheorie) and Delivering Notice

Under Swiss law, notice of termination is a unilateral, legally binding declaration that takes effect strictly upon arrival. According to the Receipt Theory (Empfangstheorie) established by the Swiss Federal Supreme Court:

Postmark dates carry no legal weight: What matters exclusively is the date and time when the notice enters the recipient's sphere of control (physical delivery into their hands, deposit in their personal mailbox, or collection notification at the Swiss Post office).
End-of-month delivery deadline: For notice intended to take effect at the end of a given month, the letter must arrive by the final working day of that month before standard business closing. If it arrives on the 1st of the next month, the termination date shifts backward by a full additional month.
Recommended method: Always send via Registered Mail (Einschreiben / Recommandé) with ample tracking buffer, or hand-deliver duplicate copies and obtain an in-person signed and dated receipt.

5. Garden Leave in Switzerland (Freistellung / Garden Leave)

In corporate Switzerland, employers frequently release departing employees from their daily working duties immediately upon notice (Freistellung). Key statutory principles include:

Full Continued Compensation Rights

The employer is legally obligated to maintain all contractual salary components throughout the notice period: base pay, pro-rata 13th-month salary, contractual allowances, and ongoing pension fund (BVG / LPP) employer contributions.

Offsetting Remaining Vacation & Overtime

Provided the garden leave duration is long enough to afford genuine rest and allow active job hunting, the employer can legally offset accrued holiday balances and overtime. In short garden leaves (e.g., 2 weeks), remaining holidays must be paid out in cash.

Early Secondary Employment & Interim Earnings (Art. 324(2) CO)

An employee on garden leave may start a new role before the notice expires. However, pursuant to Art. 324(2) CO, any compensation earned from the new employer during the overlapping period can be deducted from the former employer's wage obligations.

Frequently Asked Questions (FAQ): Employment Termination in Switzerland

When exactly must the resignation letter reach the Swiss employer?

The notice must enter the employer's physical sphere of control at or before the final working day of the month prior to standard office closing hours. Under the Swiss Receipt Theory, postmark dates have no legal bearing; actual delivery timing is the sole determinant of validity.

Is severance pay (Abfindung) standard in Switzerland upon dismissal?

Statutory severance pay (Art. 339b CO) is virtually non-existent in modern Swiss employment practice. Under federal statute, statutory severance lapses entirely if the employee qualifies for retirement or occupational pension benefits (2nd Pillar / BVG / LPP), which covers virtually all regular employees. Financial severance is only encountered in collectively negotiated social plans or individual mutual separation agreements for executive staff.

Is an employer legally obligated to state reasons for dismissal?

Under Article 335(2) CO, a termination notice is legally valid without reasons. However, if the employee formally demands written justification, the employer is legally compelled to provide a truthful written explanation. Refusal to provide reasons can be used against the employer before the Labor Conciliation Authority in cases alleging abusive dismissal.
