Employment certificate in Switzerland (certificat de travail): your rights and how to use it

What the certificat de travail must contain

Under Article 330a CO, the qualified certificat de travail (with performance assessment) must include:

Factual information: the employee's full name and date of birth; the employer's name and address; the exact start and end dates of the employment relationship; the employee's role(s) and position(s); a description of the main tasks and responsibilities.

Assessment information: an evaluation of the employee's performance (quality and quantity of work, technical skills, results achieved); an assessment of social behaviour and conduct (relationships with colleagues, management, and clients; reliability; attitude). The certificate must close with a statement about the reason for departure and — by convention in Switzerland — a standard formula wishing the employee well in their future career. The absence of this final formula is itself a negative signal to experienced Swiss HR professionals: a certificate that ends without "Wir wünschen Herrn X alles Gute" or "Nous lui souhaitons plein succès" suggests the departure was problematic.

The coded language of Swiss employment certificates

Swiss employment certificates have developed a coded vocabulary over decades — a kind of professional euphemism that allows employers to signal negative assessments without direct criticism (which would violate the benevolence requirement). Understanding the code is essential for reading certificates you receive and for knowing what to contest.

Standard positive formulas: "performed his/her tasks with great care and commitment" (sehr sorgfältig und engagiert) = clearly positive. "Completed all assigned tasks to our full satisfaction" (zu unserer vollsten Zufriedenheit) = maximum positive. "Completed tasks to our satisfaction" (zu unserer Zufriedenheit) = average, slightly negative for a professional role. "Showed efforts to complete tasks satisfactorily" = diplomatically negative — suggests performance was below expectations. The addition or removal of intensifiers ("full", "complete", "always") and qualifiers carries significant weight in the Swiss system — HR professionals trained in Switzerland read these signals immediately.

Requesting and correcting your certificate

You are entitled to request the certificat de travail at any time during or after employment. During employment, an interim certificate (certificat de travail intermédiaire) does not end the employment relationship and can be requested for legitimate purposes (job search, loan application, reconfirmation after a role change). At the end of employment, request the qualified version (with performance assessment) as the default — you can always request a simple one later if preferred, but converting a qualified to a simple certificate is a one-way option.

If the certificate contains inaccurate information, missing key responsibilities, or coded negative language you believe is unjustified, you have the right to request a correction. The process: first make the request in writing to your employer, specifying the exact corrections needed. If the employer refuses, you can file a claim at the cantonal labour court (Tribunal des prud'hommes / Arbeitsgericht) — the employer bears the burden of proving that the assessment reflects documented performance. Labour courts routinely order certificate revisions, and the process is relatively fast (typically 2–4 months for an uncontested correction). Consult a lawyer specialising in employment law before filing — the legal standards for "justifiable negative assessment" are nuanced and case-specific.

Frequently asked questions

Can I write my own certificat de travail and ask the employer to sign it?

Yes — and this is common practice in Switzerland, particularly at smaller employers who are unfamiliar with the certificate conventions. Drafting the certificate yourself allows you to frame your responsibilities accurately and avoid coded negative language. Present the draft as a "suggested template" to the employer and negotiate any changes. Many Swiss employees do this routinely; employers generally appreciate not having to draft the document themselves. Ensure the final signed version matches your CV exactly in terms of dates, title, and responsibilities.

How long should a certificat de travail be?

Proportional to seniority and length of service. For a junior role of 1–2 years: half a page to one page is standard. For a senior role of 5+ years: one to two pages, covering multiple responsibilities and projects. A certificate that is significantly shorter than expected for the role and tenure can itself signal a negative — as if the employer had little positive to say. Swiss HR professionals assess both the content and the length in relation to the seniority of the position.

Does the certificat de travail replace a reference call in Switzerland?

It supplements it, rather than replaces it. Swiss employers in most sectors expect both — the written certificate verifies the basic factual record and provides an initial assessment, while a reference call (typically requested from the hiring manager or HR, with your consent) allows more direct and candid feedback. For senior roles, 2–3 reference calls are standard. The certificat de travail is also used for administrative purposes (unemployment benefit registration at the ORP, banking references) where a phone call would not be feasible.
