Summary
Employment contracts define the legal relationship between employers and employees under Swiss labour law. They establish the working conditions, obligations, and rights governing the employment relationship from the first day of work through to termination.
This page is most relevant when you are reviewing, negotiating, or interpreting an employment contract — or when a dispute has arisen about what a contract requires.
Swiss employment contracts are primarily governed by the Swiss Code of Obligations (CO). Collective labour agreements or sector regulations may also influence contractual terms within the broader framework of

Definition of Employment Contracts
Under Swiss law, an employment contract exists where a person performs work personally and under the direction of an employer in exchange for remuneration.
The relationship is typically characterised by:
• personal performance of work
• remuneration paid by the employer
• organisational subordination within the employer’s business
Employment contracts may be agreed in writing or verbally, although written contracts are commonly used to clarify rights and obligations forming part of

Employment contracts operate alongside mandatory legal provisions. Where a contract conflicts with mandatory law, the statutory rule prevails.
Key Elements of Employment Contracts in Switzerland
Swiss employment contracts define several core elements of the employment relationship. Some are straightforward, while others become more complex depending on context.
In practice, issues rarely arise from basic contract terms, but from how specific clauses are interpreted or applied in particular situations.
Notice Periods
Contracts define the notice period required to terminate employment. These may be agreed contractually, governed by collective agreements, or set by statutory minimums.
Complexity arises where:
• contractual terms differ from statutory minimums
• collective agreements override individual contracts
• termination occurs during probation
• protected periods apply
For a detailed explanation see → Notice Periods in Switzerland
Compensation and Bonus Structures
Contracts specify remuneration, including salary, payment intervals, and additional elements such as bonuses or allowances.
Complexity arises where:
• bonuses are discretionary rather than guaranteed
• commission structures depend on variable targets
• collective agreements impose minimum standards
• compensation includes equity or deferred elements
Disputes over bonus entitlement on termination are among the most common employment law issues in Switzerland.
Non-Competition Clauses
Employment contracts may include clauses restricting post-employment activity. Their enforceability depends on specific legal conditions.
This includes:
• access to clients or trade secrets
• reasonable geographic and time limits
• formal validity requirements
Not all non-competition clauses are enforceable as drafted. For a detailed explanation see → Non-Compete Enforceability in Switzerland
Probation Period
Most contracts include a probation period. During this time:
• shorter notice periods apply
• termination is simplified
The statutory default is one month, extendable up to three months by agreement.
Additional Clauses
Contracts may include:
• confidentiality obligations
• intellectual property provisions
• references to internal policies
Enforceability depends on drafting and context.
Collective Labour Agreements and Standard Employment Contracts
Individual contracts may be supplemented or overridden by:
• Collective Labour Agreements (CLA / GAV)
• Standard Employment Contracts (SEC / NAV)
These may apply depending on:
• sector
• employer membership
• cantonal applicability
Where applicable, mandatory provisions override individual contracts.
Types of Employment Contracts
Permanent Contracts
No fixed end date. Terminated through notice.
Fixed-Term Contracts
End automatically at a defined date or upon completion of a task.
Repeated renewals may lead to reclassification as permanent employment depending on circumstances. This is frequently contested and relates to

Part-Time Contracts
Define reduced working hours and proportional compensation. Statutory protections generally remain the same.
Temporary and Agency Employment
May involve:
• employee
• agency
• end employer
Regulated under the Federal Act on Employment Services and Personnel Leasing (AVG).
When Employment Contracts Become Legally Relevant
Employment contracts typically become critical at specific moments:
• before signing or negotiating terms
• when working conditions change
• when determining notice periods
• when interpreting compensation or bonus rights
• when assessing enforceability of restrictive clauses
• when disputes arise
In these situations, contractual terms interact with statutory law and collective agreements. This is where interpretation — rather than the wording alone — often determines the outcome.
