Which requirements in a Swiss job advert are actually mandatory?

Updated: 31 August 2026

In short

Almost nothing written in the advert is. That is not encouragement, it is the legal position: under the Swiss Code of Obligations a job advert is not an offer, so it binds nobody — including the employer, who is not tied to their own list either. The market data says the same thing. One requirement is written by nearly every employer in the same occupation, and it is the language: 83.6 per cent of evaluated adverts ask for a language at professional or mother-tongue level. A vocational qualification appears in 12.4 per cent, a university degree in 5.5, a driving licence in 2.7.

This answer sets out what the cited provisions say and is not legal advice. Regulated professions are governed by cantonal law, which differs from canton to canton, and individual sectors are additionally covered by collective employment agreements. For a binding assessment of your own case, ask a legal advice centre, a trade union, the professional association or the competent cantonal authority.

That changes what you should be reading. Whether a line is mandatory is not visible in the one advert in front of you — it is visible in how many other employers advertising the same job write the same line. We counted that, and the agreement is lower everywhere than people assume. In the building and finishing trades, 54.3 per cent of adverts name a vocational qualification. In the electrical trades it is 53.6 per cent, in professional kitchens 37.2, in nursing and care 32.5, in commercial administration 21.1, in retail 14.3 and in software development 1.2 per cent.

The reverse holds too, and it is the less comfortable half. A requirement that is absent from the text is not thereby absent from the job. The hardest condition in the whole Swiss market — a driving licence for a job that consists of driving — is mentioned in 42.2 per cent of driver adverts. It applies in a hundred cases out of a hundred regardless, because a federal act says so. What is mandatory is not what the advert stresses; it is what is settled outside the advert.

Language is the only requirement most employers in the same occupation write down

Share of adverts requiring at least one language at professional or mother-tongue level, set against the share naming a formal qualification. Counted on 31 August 2026 across the open Swiss adverts on SwissJobs.app, all advert languages, apprenticeship and internship postings excluded.

Art. 7 para. 2 of the Code of Obligations, in the Fedlex English version: «The sending of tariffs, price lists and the like does not constitute an offer.» A job advert sits on that side of the line — it invites an application and promises nothing.
83.6 per cent of evaluated adverts require at least one language at professional or mother-tongue level. In English-language adverts the figure is 93.2 per cent, and in 92.2 per cent the language required is English.
English-language Swiss adverts almost never name a Swiss vocational qualification: 0.1 per cent. A university degree appears in 6.4 per cent, a driving licence in 0.4.
Of the English-language adverts that state a language requirement, 22.3 per cent need two or more working languages — the highest share of the four advert languages, against 20.4 per cent across the market. 16.2 per cent of them require German at professional level, 7.0 per cent French.
No occupation reaches sixty per cent agreement on any qualification. Across all advert languages, 44.5 per cent of electrical-trade adverts name neither a qualification nor a driving licence.
Art. 10 para. 2 of the Road Traffic Act makes a driving licence compulsory for anyone driving a motor vehicle. It is named in 42.2 per cent of driver adverts, and 58.0 per cent of the German-language ones; a licence category is named in 27.8 per cent.

A Swiss job advert is not an offer, so it binds nobody

The question assumes an advert can make something mandatory. Under Swiss contract law it cannot. The Code of Obligations does not treat a public announcement of terms as an offer but as an invitation to make one. Art. 7 para. 2 reads: «The sending of tariffs, price lists and the like does not constitute an offer.» The contrast inside the same article shows where the line runs — para. 3 adds that «the display of merchandise with an indication of its price does generally constitute an offer». The shop window binds; the price list does not.

A job advert sits with the price list. Your application is the offer; the advert is the invitation. Two consequences follow, and they pull in opposite directions. First, you can derive nothing from the advert: meeting every line named gives you no claim to be read, let alone interviewed. Second, and far more useful in practice, the employer is not bound by their own list either. They may hire someone who misses three of the eight points, and they routinely do.

This is what makes the common self-audit — «do I meet enough of the list?» — a calculation about something that does not count. The list describes what one person wanted while writing an advert under time pressure. A requirement becomes binding only when it comes from somewhere else: a statute, a permit, a professional register, a collective employment agreement. Those sources are countable and there are few of them.

One caution on the wording quoted above. Federal Swiss law is authentic in German, French and Italian; the English text published on Fedlex is a translation provided for information and has no legal force. The German original of that sentence reads «Die Versendung von Tarifen, Preislisten u. dgl. bedeutet an sich keinen Antrag», and the French «L'envoi de tarifs, de prix courants, etc., ne constitue pas une offre de contracter».

The consistency test: how much employers in one occupation actually agree

If the advert cannot tell you what is mandatory, the market can. We sorted the open adverts into occupations by job title and counted, inside each occupation, what share of employers name the same requirement. Four families were measured: a vocational qualification from Swiss apprenticeship-based or higher vocational training, a university or applied-university degree, a driving licence, and a professional registration or diploma recognition. Apprenticeship and internship postings are excluded, because those name the qualification they lead to, which answers the opposite question.

Across all advert languages the ranking runs like this. Building and finishing trades: 54.3 per cent name a vocational qualification. Electrical trades: 53.6 per cent. Professional kitchens: 37.2 per cent. Nursing and care: 32.5 per cent. Commercial administration: 21.1 per cent. Retail: 14.3 per cent. Engineering: 11.9 per cent name a degree. Software development: 1.2 per cent name a vocational qualification and 5.7 per cent a degree.

Not one figure reaches sixty per cent, and that is the finding. Even in the electrical trades, where the route into the occupation runs through a regulated apprenticeship and the work is hardly imaginable without it, more than four employers in ten do not write the qualification down. Across all advert languages, 44.5 per cent of electrical adverts name neither a qualification nor a driving licence, 40.0 per cent name the qualification alone and 13.6 per cent name both.

The usable conclusion is not that qualifications do not matter. It is a statement about spread: where half the employers leave a line out, that line is not enforced across the market. If you can do the work but lack the certificate, roughly half of that occupation's adverts contain no formal barrier at all. If you do hold it, put it where it can be found in two seconds — not because you would otherwise be excluded, but because in the other half of cases it is the difference.

The most mandatory requirement in the market appears in fewer than half the adverts

There is one requirement where any discussion of negotiability is pointless, because the employer does not set it. Art. 10 para. 2 of the Road Traffic Act settles it in a sentence. In the authentic German text: «Wer ein Motorfahrzeug führt, bedarf des Führerausweises, wer Lernfahrten unternimmt, des Lernfahrausweises» — anyone driving a motor vehicle needs a driving licence, and anyone on a learner run needs a learner permit. For a job whose content is driving, that is the whole story. No employer can waive it and no interview can soften it.

Now the count. Among adverts whose title describes a driving role — Chauffeur, Fahrerin, conducteur, autista, truck driver — the licence is mentioned at all in 42.2 per cent. Among the German-language ones it rises to 58.0 per cent. A licence category, meaning which licence is actually meant, is named in 27.8 per cent.

So well over half of these adverts require something legally unavoidable without writing it down. The reason is mundane: whoever writes a driver advert assumes the licence as automatically as they assume two hands. For the reader, though, this inverts the intuitive rule. The absence of a line is not permission. It only tells you the writer thought the point went without saying.

The same mechanism operates wherever an occupation has an official gate: the cantonal practice licence in the regulated health professions, the entitlement to work in Switzerland, statutory certificates of competence for particular activities. In nursing and care adverts, a registration or recognition is mentioned in 3.7 per cent — and the licensing duty in the regulated health professions does not depend on whether the advert remembers it. Which is why you settle such points before you apply, not during the interview.

The one line employers do agree on: the language

Across the whole evaluated market, 83.6 per cent of adverts require at least one language at professional or mother-tongue level. Nothing else is close: a vocational qualification sits at 12.4 per cent, a degree at 5.5, a driving licence at 2.7, a professional registration at 0.8. That is not a gradual difference but an order of magnitude.

The pattern holds inside occupations rather than washing out. In nursing and care adverts, 89.2 per cent carry a working-level language requirement; in driving roles 87.8 per cent; in building trades 86.5; in software development 85.2. Set that against the qualification figures from the previous section and the ordering is unambiguous. If you are going to take one line of a Swiss advert seriously, take the language line — and answer it with a level on the Common European Framework scale rather than an adjective. «Good knowledge» is not a statement about your German; B2 is.

Which language is required follows the language the advert is written in almost perfectly. German-language adverts require German in 96.6 per cent of cases, French-language adverts require French in 89.9 per cent, Italian-language adverts require Italian in 84.0, and English-language adverts require English in 92.2. The advert's own language is the requirement you cannot argue with.

The second language is where the occupations separate again, and it is the line that catches out readers arriving from abroad. Of the adverts stating a language requirement, 20.4 per cent need two or more working languages overall — but among English-language adverts the share is 22.3 per cent, the highest of the four. 16.2 per cent of English-language Swiss adverts also want German at professional level, 7.0 per cent French.

The English-language slice of this market has almost no written gates — and that misleads

If you search Switzerland in English, you are looking at a market that appears to have no formal entry requirements at all. Swiss vocational qualifications are named in 0.1 per cent of English-language adverts. Driving licences appear in 0.4 per cent. Professional registration does not appear at all. A degree, the requirement an international reader is most likely to expect, is named in 6.4 per cent.

Two things explain that, and they point in different directions. The first is composition: English-language adverts in Switzerland cluster in occupations that genuinely have no formal gate — software, engineering, finance, research, international organisations. In software development across all languages, 65.6 per cent of adverts require English at working level and 31.7 per cent require German; almost none require a certificate of any kind.

The second is convention, and it is the trap. English-language adverts are frequently written by employers whose Swiss-qualification vocabulary simply does not translate. There is no natural English rendering of «eidgenössisches Fähigkeitszeugnis», so it drops out of the English text of a role that would still, in German, be described as requiring one. The absence of the line in English is not evidence that the underlying expectation is gone.

The practical instruction that follows is specific: for any role that also exists in German, French or Italian on this market, run the ten-advert test below in that language and not in English. It costs nothing, and it is the difference between reading a translated shop window and reading the market.

If you are reading this from outside Switzerland

The requirement that decides whether you can start at all is almost never in the advert. Non-Swiss nationals need an authorisation to work here, for an employed position the application is the employer's to file, and the employer must satisfy themselves before the first working day that the entitlement exists. How that line belongs in a Swiss dossier, and how much it differs depending on nationality, is answered separately and at length in this question-and-answer section — it is not repeated here.

Beyond that, three Swiss conventions are worth knowing because they operate as requirements in practice even when unwritten. Workload is stated as a percentage — a «Pensum» — not in hours per week, and a range such as 80–100 per cent is an invitation rather than a condition. A Swiss application dossier normally includes employer references, the Arbeitszeugnis, which has no direct equivalent in most countries and cannot be reconstructed after the fact. And the document is a CV, expected to run to about two pages, not a one-page resume.

One more thing that reads as pedantry until it costs you an interview: in a regulated profession a foreign qualification is not equivalent until it has been recognised, and recognition is a procedure with a duration. A dossier stating that a recognition procedure is running, with the date it was filed, states a fact. A dossier that says nothing leaves a gap the reader will fill less generously.

And a great deal in Switzerland is cantonal, including the practice licences in the health professions. Where a rule differs by canton, an advert cannot settle it and neither can this page; the competent authority in the canton where the workplace sits can.

The ten-minute test: read ten adverts, not one

The measurement suggests a procedure anyone can run, and it is more accurate than any rule of thumb. Search for the occupation rather than the job, open the first ten results and write down which requirement appears in how many of the ten.

Whatever appears in nine or ten is an entry condition of the occupation. In most occupations that will be the language alone — which is exactly why it belongs on the first half page of your CV with a level and evidence. Whatever appears in five or six is an industry convention: useful to have, not an exclusion. Whatever appears in one or two is the handwriting of a single employer and tells you nothing about the other eight.

The second half of the test runs the other way and is usually forgotten. Ask what appears in none of the ten and applies anyway. For a driving role it is the licence. For a regulated health profession it is the cantonal practice licence. For anyone without a Swiss passport it is the entitlement to work here. Those are the real answer to the question, and not one of them can be read off the text of an advert.

Run both halves and ten minutes will tell you more about the role than a careful reading of the single advert would — because you are no longer measuring how one person likes to write, but what the market agrees on.

What this count cannot do

The measurement is taken on the title and short description of the open adverts, not on the full original text. A short description drops peripheral details before central ones, so every share reported here is a lower bound: the true figures are more likely higher than lower. That does not weaken the finding, it sharpens it in one direction. What survives into a short description is what defines the role in a few sentences — and if the qualification is missing there in four electrical adverts out of ten, the writer did not think it belonged at the front.

One decision deserves stating plainly, because it moves the numbers a long way: apprenticeship and internship postings are removed from every figure shown here. They are 5.7 per cent of the evaluated adverts and they name a vocational qualification far more often than average — the one the training leads to. Without that correction, commercial administration would read 33.4 per cent instead of 21.1. Anyone asking what is mandatory for an existing job has to take the training places out, or they measure the opposite of what they meant.

Comparisons between occupations are more robust than any single percentage, because every group was treated identically. The groups themselves are built from the job title, which is imprecise for hybrid titles, and the driving group is the smallest shown here at roughly ninety adverts — read its figures as an order of magnitude rather than a measurement to one decimal place.

The language shares do not come from the prose at all. They come from the structured language requirement carried with each advert, and only entries at professional or mother-tongue level were counted; conversational-level requirements were deliberately left out. And the thing no count can see is what happens in the mind of the person choosing. We measure what employers write, not whom they hire — which is precisely why the legal position in the first section matters.

Market figures counted on 31 August 2026 across the open Swiss adverts in our index; we publish shares, never absolute index sizes. The basis is the adverts carrying an evaluable short description, 78.7 per cent of the index, measured on title plus short description; apprenticeship and internship postings are removed, because they name the qualification they lead to, and they are 5.7 per cent of the evaluated adverts. A vocational qualification counts as named where the text mentions EFZ, CFC, AFC, Fähigkeitszeugnis, attestato federale, Berufsattest, a federal certificate or diploma of higher vocational education, brevet fédéral, apprendistato or a completed apprenticeship; a degree where it mentions a university, an applied university, a bachelor or master, ETH, EPFL, haute école or laurea; a driving licence where it mentions Führerausweis, Fahrausweis, permis de conduire, patente di guida, licenza di condurre, a driving licence or a licence category; a professional registration where it mentions a cantonal practice licence, a professional register or diploma recognition. Language shares come from the structured language requirement carried with each advert and count only entries at professional or mother-tongue level. Occupation groups are formed from the job title. The wording of Art. 7 of the Code of Obligations is from the English version published on Fedlex on 31 August 2026, which is an unofficial translation, alongside the authentic German and French texts; Art. 10 of the Road Traffic Act is quoted from the German text, as that act is not published in English.
