Jurilo by Lawise.ai:
A non-compete clause in an employment contract is intended to prevent an employee from competing with their former employer after the employment relationship ends. However, not every non-compete clause is automatically valid. In Switzerland, clear legal requirements apply for such a prohibition to be legally enforceable. In this article, you will learn when a non-compete clause is valid, when it does not apply, and what consequences a violation can have.
WHAT IS A NON-COMPETE CLAUSE IN AN EMPLOYMENT CONTRACT?
A non-compete clause is a contractual agreement whereby an employee commits to not engaging in any activity that competes with the former employer after the employment relationship ends. It may include that the employee:
does not establish their own competing business,
does not work for a competing company,
does not participate in such a company.
Legal basis:
REQUIREMENTS FOR A VALID NON-COMPETE CLAUSE
For a non-compete clause to be legally valid in Switzerland, the following conditions must be met:
1. Written agreement
The non-compete clause must be agreed upon in writing. An oral agreement is invalid (Art. 340 para. 1 CO).
2. Access to trade secrets or customer base
The employee must have gained access to the customer base or manufacturing and trade secrets in the course of their work (Art. 340 para. 2 CO).
Example: A sales manager with access to pricing calculations and customer lists.
3. Significant harm to the employer
The use of this knowledge must be capable of significantly harming the employer. It is not sufficient that a theoretical risk exists – there must be a real danger.
4. Reasonable limitation
The prohibition must be reasonable in terms of location, time, and subject matter (Art. 340a CO). As a guideline:
Maximum duration of 3 years (longer duration only in exceptional cases)
Geographically limited to the employer's area of operation
Only related to actually competing activities
WHEN IS A NON-COMPETE CLAUSE INVALID?
A non-compete clause is wholly or partially invalid if:
it was not agreed upon in writing,
the employee had no access to sensitive information,
it unfairly restricts the employee's economic advancement,
it is excessive in terms of time or geography.
In such cases, the judge can annul the prohibition or reduce it to a permissible extent (Art. 340a para. 2 CO).
WHEN DOES A VALID NON-COMPETE CLAUSE BECOME VOID?
A valid non-compete clause loses its effect if:
the employer terminates the employment relationship without the employee having given justified cause (Art. 340c para. 2 CO),
the employee terminates for a reason attributable to the employer (Art. 340c para. 2 CO),
the employer no longer has a significant interest in enforcement (Art. 340c para. 1 CO).
CONSEQUENCES OF VIOLATING A NON-COMPETE CLAUSE
If the employee violates a valid non-compete clause, the following consequences may apply:
Liability for damages to the employer (Art. 340b CO)
Payment of a contractual penalty, if agreed
Injunction to remedy the contractual violation (if agreed in writing)
NON-COMPETE CLAUSE AND WAITING PERIOD COMPENSATION
Unlike in other countries, waiting period compensation is not mandatory in Switzerland. However, if compensation is absent, the non-compete clause is scrutinized more strictly for reasonableness.

CONCLUSION
A non-compete clause is only valid under clear legal requirements. Employers should carefully draft the prohibition and limit it to a reasonable extent. Employees, in turn, should carefully check whether the conditions are met before signing – and seek legal advice if in doubt.
FAQ ABOUT NON-COMPETE CLAUSES
Must a non-compete clause be agreed upon in writing?
Yes. A non-compete clause is only valid if it was concluded in writing. An oral agreement is legally ineffective.
Does a non-compete clause also apply to fixed-term employment contracts?
Yes, provided the legal requirements are met. The duration of the contract is irrelevant to validity.
How long may a non-compete clause last?
Generally a maximum of 3 years. A longer duration is only permissible under special circumstances and must be well justified.
What does "reasonable" mean regarding location, time, and subject matter?
The prohibition may not unreasonably restrict the employee in their professional future. It must be limited to the employer's area of operation and region.
What happens if the non-compete clause is too broadly defined?
The judge can reduce the prohibition to a permissible extent or annul it entirely if it is excessive.
When does a non-compete clause automatically become void?
If the employer terminates the employment relationship without the employee having given justified cause, or if the employer no longer has an interest in enforcement.
What is a contractual penalty in connection with a non-compete clause?
This is a contractually agreed monetary penalty that the employee must pay if they violate the prohibition. However, it does not automatically replace damages.
Can the employer claim damages in addition to the contractual penalty?
Yes, if additional damage has occurred, the employer can demand damages in addition to the penalty.
Can the employer demand that I cease the competing activity?
Yes, if this was agreed in writing and the balance of interests justifies it, they can file for an injunction.
What can I do if I signed a non-compete clause that restricts me too much?
You can have the prohibition reviewed by a court. The judge can reduce it to a reasonable extent or annul it entirely. Legal advice is recommended in this case.
