Job interviews and jobs in Switzerland: the questions a recruiter is not allowed to ask
“Do you have children, or plan to?” “Are you a union member?” “Have you ever had health problems?” These questions are still asked in job interviews in French-speaking Switzerland. They are unlawful in most cases, and they expose the employer to compensation for discrimination in hiring. The candidate, for their part, has the right not to answer, and even to answer evasively.
This guide is written first for recruiters, who want a compliant interview without giving up useful information, and it also reads from the candidate’s side. It explains the rule of the Code of Obligations, lists the prohibited questions and the permitted ones, specifies when an exception exists, what the employer risks, and how to build an interview grid that holds up. Everything is drawn from the legal texts, the case law of the Federal Supreme Court and the pages of the cantonal authorities.
The rule: only questions related to suitability for the position
Everything starts with one sentence of the Code of Obligations, which applies from the application stage: the employer may process data concerning the employee only to the extent that the data relate to the employee’s suitability for the job or are necessary for the performance of the employment contract (art. 328b CO). Asking a question is already collecting data. Three consequences:
- The link with the position is the only criterion. A question is permitted if the answer helps judge whether the candidate can do the work, or if it is necessary to conclude and perform the contract. Everything else belongs to the private sphere, protected by art. 328 CO and by the Data Protection Act. The Federal Supreme Court derives a presumption from this: processing of the data covered by art. 328b CO is presumed lawful, processing of other data is presumed unlawful (ATF 123 III 129).
- The position moves the line. The same question can be prohibited for one position and permitted for another: debts for a salesperson, no; for a wealth manager, yes. It is the concrete requirement of the position that justifies the question, never curiosity or company policy.
- Discrimination is a separate fault. The Gender Equality Act prohibits discrimination on the basis of sex, directly or indirectly, in particular on the basis of civil status, family situation or, for women, pregnancy, and this prohibition applies in particular to hiring (art. 3 GEA). A question about pregnancy is therefore not only an infringement of personality rights: it is evidence of discrimination.
The principle applies to the interview, but also to the application form, tests, references and online searches.
The prohibited questions, unless the position specifically requires them
Pregnancy, plans for children, family planning
All questions about a current or future pregnancy are prohibited, recalls the Jura-Neuchâtel data protection commissioner in a 2018 opinion. Only exceptions: work that is dangerous or incompatible with pregnancy, prohibited by public law for pregnant women, or a very short engagement for a specific situation. The candidate has no obligation to disclose a pregnancy, confirms the Vaud equality office.
Civil status, family situation, childcare
“Are you married?”, “Who looks after your children?”, “Does your spouse work?”: these questions target the family situation, a discrimination criterion expressly cited by art. 3 GEA. If the position requires travel or irregular hours, ask about the constraint, not the family: “The position involves two nights a week away, is that workable for you?”
Health, illnesses, disability, treatments
Health belongs to the intimate sphere. The question is only permitted if a specific condition would make the work impossible or dangerous: ability to carry loads for a handling job, eyesight for a driver. Even then, it is limited to suitability for that position, never the full medical file.
Criminal record and criminal proceedings
Requesting an extract from the criminal record is “in principle exceptional”, according to the City of Lausanne. It is permitted for a position of trust where an offence would weigh directly on the work, managing assets or cash for example. For a regular activity with minors or vulnerable persons, the employer may request the special extract, which only shows current activity bans.
Debts, debt enforcement, financial situation
Prohibited for most positions. Permitted when the position involves handling money or valuables, or financial responsibility: the employer may then ask for an extract from the debt enforcement register, which the candidate obtains themselves from the office.
Religion, beliefs, union, political commitment
These questions are only permitted in a “Tendenzbetrieb”, an organisation whose activity rests on these beliefs: a church, a party, a union, a campaigning association. For all other employers, they are unlawful. The Federal Supreme Court allows the employer to ask about union membership after the contract is concluded, solely to apply a collective agreement (ATF 123 III 129).
Sexual orientation, origin, private life
No link with suitability, so no place in an interview. Mind the nuance: asking about nationality or residence permit is lawful, because the employer must know whether it can hire without authorisation. Asking “where does your name come from” is not.
The permitted questions, and those that become permitted depending on the position
Education, career, skills, professional references
Degrees, experience, responsibilities, results, languages, tools mastered, reasons for previous departures: this is the heart of the interview, and the City of Lausanne sums up the rule by inviting the employer to limit its questions to the candidate’s education, career and professional prospects.
Availability, notice period, desired workload
Possible start date, current notice period, workload, acceptable hours, geographical mobility: these elements are necessary to conclude the contract.
Nationality, work permit
Necessary to know whether hiring is possible without a quota or prior authorisation. Our guide to work permits for EU citizens details the cases.
Salary expectations and current salary
Lawful, even if the candidate is not obliged to disclose their current salary. On Licorn, expectations are in the profile before the interview; see our job market barometer for orders of magnitude.
Health, criminal record, debts: yes, when the position requires it
These questions become lawful again when a concrete requirement of the position justifies them: physical fitness for strenuous work, good repute for a position of trust, solvency for managing funds. The employer must be able to explain the link, and limit itself to what is necessary.
Criminal proceedings affecting the ability to work
The Federal Supreme Court allowed the cancellation of a contract because a candidate had kept silent, during the interview, about pending criminal proceedings likely to seriously affect her ability to work (ATF 132 II 161). The candidate must spontaneously report what would prevent them from performing the contract.
Candidate side: the right not to answer, and its limits
Refuse to answer, or answer inaccurately
For an unlawful question, the candidate may refuse to answer or answer inaccurately without legal consequence: this is the “right to lie” recognised by legal scholarship and adopted by the City of Lausanne for irrelevant criminal records. On pregnancy, the Vaud equality office is explicit: you have the right not to answer truthfully.
Better to answer evasively than to denounce the question
The same office advises giving a false answer rather than hiding behind the unlawfulness of the question, because pointing out the illegality may be enough to get the application rejected. A neutral answer such as “nothing in my situation prevents me from holding this position” closes the subject.
For a lawful question, lying has a price
Lying about a degree, an experience, a criminal record required for a position of trust or an inability to do the work is deceiving the employer. The employer may invalidate the contract for fraud or fundamental error (arts. 23 and 28 CO), and a dismissal on this ground is not abusive.
The duty to inform spontaneously
The candidate must disclose on their own initiative what would make performance of the contract impossible or seriously compromised: a known incapacity for work, an activity ban, or pending criminal proceedings affecting their ability to work (ATF 132 II 161).
Keep a record
A candidate who believes they were rejected for a discriminatory reason should note the question, the date and the people present as soon as they leave the interview. The Gender Equality Act then gives them a short period to act, see below.
Beyond questions: references, social media, tests, application file
References and former employers
The Data Protection Act requires informing the person when data are collected from third parties (art. 19 DPA). In practice: ask the candidate which references to contact and for their agreement, limit yourself to questions related to the position, and do not contact the current employer without their explicit go-ahead. A former employer who gives inaccurate and defamatory information breaches art. 328 CO for its part.
Social media
Looking at a public professional profile, LinkedIn for example, stays within the scope of suitability. Digging through private accounts, holiday photos or political opinions has no link with the position and breaches the DPA’s proportionality principle. The candidate must be informed of searches made about them.
Tests and examinations
Skills tests, role plays and psychometric tests are permitted if they measure an aptitude required by the position and the candidate is informed. A pre-employment medical examination is only permitted if the position justifies it, and the doctor only passes on the conclusion on fitness to the employer, not the diagnosis.
Official extracts
Ordinary criminal record extract for a position of trust, special extract for an activity with minors or vulnerable persons, debt enforcement extract for financial responsibility: always ordered by the candidate themselves, never by the employer, and only for positions that justify it.
The application file
The data of an unsuccessful candidate no longer have a purpose once the position is filled: return or destroy the file, unless the candidate agrees to its being kept for another position. The candidate has a right of access to what you have collected about them (art. 25 DPA), including interview notes.
What the employer risks
Compensation for discriminatory refusal to hire
If the refusal to hire is linked to sex, pregnancy or family situation, the rejected person can only claim compensation from the employer, which will not exceed the amount of three months’ salary (art. 5 paras. 2 and 4 GEA). They cannot demand to be hired.
The obligation to give written reasons
The person who is not hired and who claims discrimination may require the employer to give written reasons for its decision (art. 8 para. 1 GEA). An offer withdrawn right after a pregnancy is announced is, for the Vaud equality office, strong evidence of discrimination.
A three-month period for the candidate
The person who wants compensation must bring an action within three months from the time the refusal to hire was communicated, failing which the right lapses (art. 8 para. 2 GEA). At the hiring stage, the easing of the burden of proof in art. 6 GEA does not apply: it is up to the candidate to make the discrimination plausible, hence the importance of the written reasons.
Infringement of personality rights and data protection
Collecting data unrelated to the position is an unlawful infringement of personality rights (arts. 328 and 328b CO) and a breach of the DPA. The candidate may demand access, rectification or destruction of the data, and claim redress. Breaching certain DPA obligations, such as the duty to inform, is also punishable by a fine.
The reputational risk
An interview recounted on social media or a review platform is read by every subsequent candidate. In occupations where candidates are scarce, this is often the highest cost.
Building a compliant interview grid, without losing information
Recruiters who ask unlawful questions are generally looking for legitimate information: availability, reliability, stability. It can be obtained differently:
- Start from the job description. List the concrete requirements of the position, hours, travel, carrying loads, financial responsibility, contact with minors, then phrase one question per requirement. “The position requires being on site on Saturdays, is that possible for you?” replaces any question about the family.
- Same grid for everyone. The same questions in the same order for every candidate, with a score per criterion. It is the best protection against an accusation of discrimination, and a better decision tool.
- Announce what you collect. References, tests, official extracts, online searches: tell the candidate beforehand, and ask for their agreement when third parties are contacted.
- Note facts, not impressions. “Managed a team of six for three years” holds up in court; “does not seem very available” is evidence of discrimination. The candidate can ask to read your notes.
- Train those who interview. The unlawful question rarely comes from HR, more often from the future line manager who is “getting to know” the candidate. A page of instructions before each interview is enough.
For occupations where unemployment exceeds 5%, the interview is also part of the procedure of the job vacancy notification requirement, which requires inviting suitable candidates.
The Licorn method: conditions are set, the interview is about skills
Constraints are in the profile
Workload, location, remote work, salary, type of contract: the candidate set them before any contact. The recruiter no longer has to guess them through questions about private life.
Matching is based on objective criteria
Skills, experience, requirements of the position: the proposal starts from what is relevant to the job, which is what art. 328b CO requires.
The interview serves its purpose
Checking skills, presenting the team, answering the candidate’s questions. Our guide for recruiters explains how to publish your conditions and receive profiles that already match.
Frequently asked questions about prohibited interview questions
No, unless the work is dangerous or incompatible with pregnancy, or it is a very short engagement for a specific situation. Pregnancy and family situation are discrimination criteria cited by art. 3 GEA. The candidate does not have to disclose a pregnancy in an interview and may answer an unlawful question inaccurately.
No. The ordinary extract is only justified for a position of trust where an offence would weigh directly on the work. The special extract, limited to activity bans, may be requested for a regular activity with minors or vulnerable persons, on written confirmation from the employer. In both cases, the candidate orders the extract.
Faced with an unlawful question, yes, without legal consequence: this is the position of legal scholarship, adopted by the City of Lausanne and the Vaud equality office. Faced with a lawful question, no: a lie about a degree, an experience or an inability to do the work allows the employer to invalidate the contract for fraud or fundamental error, and the candidate must even spontaneously report criminal proceedings that would affect their ability to work (ATF 132 II 161).
The question itself is an infringement of personality rights, rarely sanctioned on its own. The real risk is the refusal to hire that follows: if the rejected person makes discrimination plausible, they can obtain compensation of up to three months’ salary (art. 5 GEA), after demanding written reasons and acting within three months (art. 8 GEA).
A public professional profile, yes, to the extent that it informs about suitability for the position. Private accounts, no: their content has no link with the job and the DPA requires proportionality. In all cases, the candidate must be informed of the searches made about them.
Not without their explicit agreement. The DPA requires informing the person when data are collected from third parties (art. 19), and a call to the current employer may cost them their job. Limit yourself to the references the candidate gives you, and to questions related to the position.
In short
In Switzerland, a recruiter may only ask questions that help judge suitability for the position or conclude the contract (art. 328b CO). Pregnancy, family, health, criminal record, debts, religion, union, orientation and origin are out of scope, unless the position concretely requires them. The candidate may decline to answer, or answer evasively, an unlawful question, but owes the truth on everything that matters for the job. An employer who rejects a candidate for a pregnancy or a family situation faces compensation of up to three months’ salary.
The interview grid that protects best is also the one that recruits best: questions drawn from the job description, the same for everyone, scored on facts.
