Data Protection at Work in Switzerland

What Data Can Employers Collect?

Employers may only process employee data that is necessary for the employment relationship. This covers: payroll, social insurance contributions, attendance and time recording, performance data directly related to the role, and health data required for legal compliance (illness reporting, safety). Special categories (health, religion, political views) require a stronger justification. Employees have the right to request access to all data held about them (Art. 25 nDSG), the employer must respond within 30 days.

Monitoring, Surveillance and Limits

The Labour Act (ArG Art. 26) prohibits using monitoring systems whose primary purpose is to control employee behaviour or performance. However: time recording systems (compliant), access logging for security, quality monitoring in call centres (with prior notice) are permitted. Video surveillance for safety or anti-theft purposes is allowed but camera footage cannot be used for routine performance assessment. Email and internet monitoring: permitted only for security or compliance reasons, with prior employee notice, and not systematically reviewing personal communications.

Employee Rights Under nDSG

Key employee rights: access right (see all data held about you, free, within 30 days), correction right (have inaccurate data corrected), objection right (object to processing for which no legitimate basis exists). Employers must provide a privacy notice explaining what data is collected, why, and for how long. Data breaches affecting employees must be reported to the Federal Data Protection and Information Commissioner (FDPIC) if there is a risk of harm.

Frequently Asked Questions

Can my employer read my work emails?

Only if they have informed you in advance and have a legitimate purpose (security, compliance). Systematic and undisclosed monitoring of personal communications in work accounts is unlawful. Many employers have a policy distinguishing between business and personal use of work email.

Do I have the right to know what personal data my employer holds about me?

Yes. The nDSG gives every person the right to request a copy of all personal data processed about them. The employer must respond within 30 days and cannot charge a fee for standard requests.

Can my employer share my data with a future employer?

Only with your consent or as legally required (e.g. confirming dates of employment). References given without your consent or containing inaccurate statements can give rise to claims under nDSG and general tort law.

What is the 13th month salary in Switzerland?

The 13th month salary in Switzerland refers to an additional monthly salary paid once a year, typically in December. It is included in annual salary benchmarks as standard: when a Swiss employer quotes CHF 120,000 per year, this normally means 13 monthly payments of approximately CHF 9,231 each, not 12 payments of CHF 10,000. The 13th month is governed by the employment contract or collective agreement (GAV), not by statute. It is subject to social contributions (AHV/ALV) and income tax. Always clarify with a prospective employer whether a quoted annual figure includes or excludes the 13th month.

How do Swiss notice periods work for employment contracts?

Under Swiss law (Code of Obligations, Art. 335c), notice periods during probation (default 1 month, up to 3 months by agreement) are 7 days. After probation, statutory notice periods are: 1 month during the first year, 2 months in years 2 to 9, and 3 months from year 10 onwards. Notice must be given in writing by end of calendar month (or end of the agreed notice period month). Contractual or GAV notice periods can be longer but cannot be shorter than statutory minimums. Protected periods exist (illness, accident, pregnancy) during which termination is suspended or prohibited.
