Employment Law in Switzerland

Swiss employment law balances employer flexibility with employee protection through a framework of mandatory minimum standards, freedom of termination, and sector-specific collective agreements. The Code of Obligations (OR), the Labour Act (ArG), and various social insurance laws together define the rights and obligations of both parties. Whether you are hiring your first Swiss employee or managing an established workforce, understanding these rules is essential to avoid costly disputes and compliance failures. This guide covers the full scope of employment law, drawing on our detailed resource on Swiss employment law essentials.

Swiss Employment Law Overview

Employment relationships in Switzerland are governed primarily by federal law. There is no single employment code — the rules are spread across multiple statutes, each addressing different aspects of the relationship:

• Code of Obligations (OR) Art. 319-362: Core employment law — contract formation, notice periods, termination, non-compete clauses, overtime, and employee protections
• Labour Act (ArG): Working hours, rest periods, night work, Sunday work, and health/safety requirements. The State Secretariat for Economic Affairs (SECO) publishes detailed guidance on working conditions and labour standards
• Federal Act on Gender Equality (GlG): Prohibition of gender-based discrimination in employment
• Social insurance acts: AHV/IV, ALV, BVG, UVG, and other mandatory insurance schemes

Cantonal law plays a limited role — primarily in enforcing labour standards and administering social insurance. The substantive employment rules are federal and apply uniformly across all 26 cantons.

The system is characterised by a high degree of party autonomy: employers and employees can agree on terms that exceed the statutory minimums. But the minimums are mandatory (zwingend or halbzwingend) and cannot be contracted away to the employee’s detriment. This creates a floor of protection while allowing significant flexibility in structuring the employment relationship.

The Legal Framework

Code of Obligations (OR)

The OR is the primary source of Swiss employment law. Articles 319-362 cover:

• Formation and content of employment contracts
• Duties of both employer and employee
• Salary payment and protection
• Notice periods and termination procedures
• Protection against abusive dismissal
• Continuation of salary during illness, accident, and military service
• Non-compete clauses and trade secret protection
• Employer’s liability for references

The OR provisions are classified as either mandatory (cannot be modified by contract) or semi-mandatory (can only be modified in favour of the employee). For example, the minimum notice periods in Art. 335c are semi-mandatory — contracts can set longer periods but not shorter ones.

Labour Act (ArG)

The Labour Act regulates working conditions — maximum working hours, rest periods, night and Sunday work, and workplace health and safety. It applies to most private-sector employees but excludes certain categories: agricultural workers, domestic employees, managers and senior officers, and employees of public administrations (governed by separate public employment laws).

The ArG is enforced by cantonal labour inspectorates (Arbeitsinspektorate), which can conduct workplace inspections and issue orders requiring compliance.

Collective Labour Agreements (GAV)

Collective agreements between employer associations and trade unions supplement the statutory framework for specific sectors. When a GAV is declared generally binding (allgemeinverbindlich) by the Federal Council, its terms apply to all employers and employees in the sector, regardless of whether they belong to the signatory associations or unions.

Major sectors covered by generally binding GAVs include construction, hospitality, cleaning, logistics, and security.

Employment Contracts

Swiss employment contracts can be concluded orally, in writing, or by implied conduct. No particular form is required for the contract to be valid. However, written contracts are universal in practice and essential for documenting specific terms that the parties wish to agree upon.

Required Content

While no specific content is legally mandated for the contract itself, the employer must provide written information on the following within one month of commencement:

• Names of the parties
• Start date
• Function or position
• Salary and any supplements
• Weekly working hours

Contract Types

Individual employment contract (Einzelarbeitsvertrag): The standard form, governed by OR Art. 319-343. This can be open-ended (unbefristet) or fixed-term (befristet).

Fixed-term contracts: End automatically at the agreed date without notice. Chain fixed-term contracts (repeated renewals) may be reclassified as open-ended if they lack objective justification for the fixed term.

Part-time contracts: Subject to the same rules as full-time contracts, with salary and benefits prorated. Part-time employees are entitled to pro-rata holiday, social insurance coverage, and protection against unfair dismissal.

Temporary agency work: Governed by the Federal Act on Employment Services and Staff Leasing (AVG). Temporary agencies must hold a cantonal or federal licence. The actual employer for social insurance and most employment law purposes is the agency, not the client company.

Key Contractual Provisions

Several provisions deserve particular attention:

Probationary period: Defaults to 1 month if not specified. Can be extended to up to 3 months by written agreement. During probation, either party can terminate with 7 days’ notice.

Salary: Swiss law does not prescribe a minimum salary (except in cantons with cantonal minimums or sectors covered by GAVs). Salary must be paid at least monthly, in Swiss francs, unless another currency is agreed. The 13th-month salary is not legally required but is standard practice across most sectors.

Non-compete clauses: Valid only if in writing, the employee has access to clientele or business secrets, and the restriction is reasonable in scope, geography, and duration (maximum 3 years). Courts actively police the reasonableness requirement and frequently narrow or invalidate overly broad clauses.

For a full discussion of contract drafting considerations, see our employment law guide.

Probationary Period

The probationary period serves as a trial phase during which either party can terminate the employment with shortened notice (7 days). The statutory default is 1 month, which can be extended to a maximum of 3 months by written agreement. It cannot be extended beyond 3 months, and any contractual provision purporting to do so is void.

During the probationary period:

• Either party can terminate with 7 days’ notice, effective on any day (not required to be the end of the month)
• The protections against dismissal during illness, pregnancy, and military service do not apply during the first month — but do apply if the probation is extended beyond 1 month
• There is no requirement to give a reason for termination

If an employee’s probation is interrupted by illness, accident, or military service, the probationary period is extended by the duration of the absence.

Working Hours and Rest Periods

Maximum Hours

The Labour Act sets absolute maximum weekly working hours:

• 45 hours: Industrial enterprises, office workers, technical employees, retail staff, employees of large enterprises
• 50 hours: All other workers

These limits apply to actual working time, excluding breaks. They are not the same as standard contractual working hours — most contracts set standard hours at 40-42.5 per week.

Rest Periods

• Daily rest: At least 11 consecutive hours between working days
• Breaks: 15 minutes if the working day exceeds 5.5 hours, 30 minutes if it exceeds 7 hours, 1 hour if it exceeds 9 hours
• Weekly rest: At least one full day off per week (normally Sunday)
• Night work (23:00-06:00): Generally prohibited without a cantonal permit. Employees required to work regular night shifts are entitled to a 10% time compensation and regular medical examinations

Sunday and Public Holiday Work

Sunday work requires a cantonal permit and entitles the employee to a 50% wage supplement (unless compensated with equivalent time off). Public holidays are regulated by cantonal law — Switzerland has no uniform national public holiday system. The number of public holidays varies from 8 to 15 depending on the canton.

Overtime and Additional Work

Swiss law distinguishes between two types of extra hours:

Overtime (Ueberstunden)

Hours worked beyond the contractual working time but within the ArG maximum (45 or 50 hours). Overtime must be compensated either with:

• A 25% wage supplement, or
• Equivalent time off (if agreed between the parties)

Written agreements can waive the right to overtime compensation for certain categories of employees (typically managers and senior staff). However, this waiver must be explicit and is narrowly interpreted by courts.

Additional Work (Ueberzeit)

Hours worked beyond the ArG maximum (45 or 50 hours). Additional work is more strictly regulated:

• Must be compensated with a 25% wage supplement (mandatory — cannot be waived)
• Maximum 2 hours per day
• Maximum 170 hours per year (for a 45-hour week) or 140 hours per year (for a 50-hour week)
• Must be ordered or approved by the employer

The distinction matters because overtime compensation can be contractually modified, while additional work compensation is mandatory and cannot be contracted away.

Termination of Employment

Swiss employment law follows the principle of freedom of termination — either party can terminate an open-ended contract at any time by giving the required notice. No reason is needed for ordinary termination.

Notice Periods

The statutory minimum notice periods (semi-mandatory — can be extended but not shortened by contract):

Immediate Termination (Fristlose Kuendigung)

Either party can terminate immediately for cause (wichtiger Grund) under Art. 337 OR. Important cause exists when circumstances make it unreasonable to expect the relationship to continue — for example:

• Gross misconduct (theft, fraud, violence)
• Persistent refusal to work
• Serious breach of confidentiality
• Employer’s failure to pay salary despite formal demand

Immediate termination without sufficient cause exposes the terminating party to damages — up to 6 months’ salary for the employee, or restitution of the salary the employer would have had to pay through the notice period.

Summary Dismissal in Practice

Swiss courts set a high threshold for immediate termination. Employers should document the misconduct, give the employee an opportunity to respond (Anhoerung), and act promptly. Waiting too long after discovering the grounds for termination can be interpreted as acceptance of the situation, weakening the employer’s right to dismiss immediately.

Protection Against Dismissal

While Swiss law does not require cause for termination, it prohibits certain types of dismissal:

Abusive Dismissal (Missbräuchliche Kuendigung)

Art. 336 OR lists specific grounds that render a dismissal abusive:

• Dismissal due to personal characteristics of the employee (race, religion, political opinion)
• Dismissal because the employee exercised a constitutional right
• Dismissal solely to prevent a claim from arising (e.g., dismissing an employee just before a bonus vesting date)
• Dismissal due to union membership or activity
• Dismissal during or because of serving as an employee representative

An abusive dismissal is not void — the termination stands. But the employee is entitled to compensation of up to 6 months’ gross salary, determined by the court based on the circumstances. The employee must challenge the dismissal in writing before the end of the notice period and file a claim within 180 days of the employment ending.

Temporal Protection (Sperrfristen)

During certain periods, the employer is prohibited from giving notice. If notice is given during a protected period, it is void and must be re-issued after the period ends:

• Illness or accident: 30 days (year 1), 90 days (years 2-5), 180 days (year 6+)
• Pregnancy and 16 weeks after birth
• Military or civil service: During service and 4 weeks before/after
• Swiss humanitarian operation abroad: Duration of service

If the employee falls ill after notice is given, the notice period is suspended for the duration of the protected period and resumes afterwards.

Social Insurance System

Switzerland’s social insurance system is built on three pillars and several supplementary schemes:

First Pillar: AHV/IV/EO

State pension, disability, and income replacement insurance. Funded by equal employer and employee contributions of 5.3% each on all salary (no ceiling). Provides a basic retirement pension of CHF 1,225-2,450 per month depending on contribution history.

Second Pillar: BVG/LPP

Occupational pension fund (mandatory for employees earning more than CHF 22,050 per year). The employer must pay at least 50% of the total BVG contribution. Contribution rates increase with age: 7% (25-34), 10% (35-44), 15% (45-54), 18% (55-65) of the coordinated salary (salary between CHF 22,050 and CHF 88,200).

Accident Insurance: UVG/LAA

Mandatory for all employees. Covers both occupational and non-occupational accidents. The employer pays the non-occupational accident premium; the employee pays the occupational accident premium. For employees working 8+ hours per week, non-occupational accident insurance is included.

Unemployment Insurance: ALV/AC

Employer and employee each contribute 1.1% on salary up to CHF 148,200. There is an additional solidarity contribution of 0.5% on salary above CHF 148,200.

Family Compensation: FAK/CAF

Funded by employer contributions of 1-3% depending on canton (employees do not contribute). Provides child allowances (CHF 200-250/month per child) and education allowances (CHF 250-300/month per child in training).

Collective Labour Agreements

Collective labour agreements (GAV/CCT) are a significant feature of Swiss employment law, particularly in sectors where they have been declared generally binding.

Sectors with Generally Binding GAVs

Major generally binding agreements include:

• Construction (LMV/CCT Construction): Minimum wages, working hours, inclement weather provisions, training levies
• Hospitality (L-GAV Gastgewerbe): Minimum wages by qualification level, working hours, tip regulations
• Cleaning: Minimum hourly wages, overtime rules, holiday provisions
• Temporary work (GAV Personalverleih): Equal pay requirements, placement conditions
• Logistics and transport: Working hours, rest periods, driver-specific rules

Effect

When a GAV is generally binding, its terms override less favourable individual contract provisions. An employer in a covered sector must comply even if the employer is not a member of the signatory employer association. Enforcement is handled by joint commissions (Paritaetische Kommissionen) with power to inspect, fine, and report violations.

Interaction with Individual Contracts

Individual contracts can exceed GAV minimums but cannot fall below them. If a GAV sets a minimum hourly wage of CHF 22, an individual contract providing CHF 20 is void on that point and the GAV rate applies.

Employer Obligations for Foreign Workers

Employers hiring foreign nationals in Switzerland must comply with immigration and work permit requirements:

EU/EFTA Nationals

Under the Agreement on the Free Movement of Persons, EU/EFTA nationals have the right to live and work in Switzerland. For employment exceeding 3 months, the employee needs a residence permit (B permit or L permit). The employer must register the employee with the cantonal migration office within 14 days.

For short-term assignments (up to 90 days per calendar year), no work permit is needed — only an online registration with the competent authorities (Meldepflicht).

Non-EU Nationals

Non-EU nationals face stricter requirements. The employer must demonstrate that no suitable Swiss or EU/EFTA candidate is available (labour market test), and the employee must be a qualified specialist. Quotas apply to B permits for non-EU nationals.

The work permit application is filed by the employer with the cantonal labour market authority (Arbeitsmarktbehoerde). Processing takes 4-8 weeks. The employee cannot begin working until the permit is issued.

Posted Workers

Foreign employers posting workers to Switzerland for temporary assignments must comply with the Posted Workers Act (EntsG): minimum wage requirements, working hour limits, and mandatory registration with the relevant authority.

Practical Considerations for Employers

Reference Letters

Swiss law gives employees the right to a reference letter (Arbeitszeugnis) at any time during or after employment (Art. 330a OR). The reference must be truthful and benevolent — it should accurately describe the employee’s performance and conduct while being worded in a way that does not unfairly prejudice the employee’s future career. Courts take reference letter disputes seriously, and employers who issue unfairly negative references can face damages claims.

Data Protection

Employer processing of employee personal data is subject to the revised Federal Act on Data Protection (revDSG, effective September 2023). Employers may only process data that is relevant to the employment relationship, must inform employees about data processing activities, and must protect data with appropriate technical and organisational measures.

Workplace Health and Safety

The Labour Act and its ordinances impose detailed requirements on workplace safety, including maximum temperatures, lighting standards, ergonomic requirements, and hazardous substance handling. Compliance is monitored by cantonal labour inspectorates and SUVA (the Swiss National Accident Insurance Fund).

Disputes and Jurisdiction

Employment disputes up to CHF 30,000 are heard by conciliation authorities (Schlichtungsbehoerden) and are free of court costs. Disputes above CHF 30,000 are subject to regular civil procedure. Many cantons have specialised labour courts (Arbeitsgerichte) with employee and employer representatives on the bench.

Frequently Asked Questions

Do employment contracts need to be in writing in Switzerland?

No. Swiss employment contracts can be concluded orally, in writing, or by implied conduct. However, certain provisions must be in writing to be valid: non-compete clauses, overtime compensation waivers, and probationary period agreements exceeding 1 month. In practice, written contracts are standard and strongly recommended.

What are the minimum notice periods in Switzerland?

During probation: 7 days. After probation: 1 month (year 1), 2 months (years 2-9), 3 months (year 10+). Notice must be given to the end of a calendar month. These are statutory minimums — contracts may set longer periods.

Can an employer dismiss an employee without giving a reason?

Yes. Swiss law operates on freedom of termination. However, dismissals based on discriminatory grounds, exercise of constitutional rights, or union membership are classified as abusive and entitle the employee to compensation of up to 6 months’ salary.

What are the maximum working hours?

45 hours per week for industrial, office, retail, and large enterprise workers. 50 hours for all others. These exclude breaks. Most contracts set standard hours at 40-42.5 per week.

Is there a minimum wage in Switzerland?

No national minimum wage. Cantonal minimums exist in Geneva, Basel-Stadt, Neuchatel, Jura, and Ticino. Many sectors have binding minimum wages through collective agreements.

How much annual leave are employees entitled to?

4 weeks (20 days) for employees aged 20+; 5 weeks (25 days) for those under 20. Many employers provide 5 weeks as standard. Public holidays (8-15 days by canton) are separate.

What social insurance contributions must employers pay?

AHV/IV/EO at 5.3%, ALV at 1.1% up to CHF 148,200, BVG (at least 50% of total), UVG non-occupational premiums, and FAK at 1-3%. Total: approximately 15-20% of gross salary.

What happens if an employee is sick during the notice period?

The notice period is suspended for the protected period: 30 days (year 1), 90 days (years 2-5), 180 days (year 6+). After the protected period, the notice resumes to the end of the next calendar month.

Are non-compete clauses enforceable in Switzerland?

Yes, with restrictions. They must be in writing, the employee must have access to business secrets or clientele, the restriction must be reasonable in scope, geography, and duration (max 3 years). Courts frequently narrow overly broad clauses.

What is a GAV (collective labour agreement)?

A binding agreement between employer associations and trade unions setting minimum terms for a specific sector. When declared generally binding by the Federal Council, it applies to all employers and employees in the sector regardless of union membership.
