Do I have to disclose that I am ill when applying for a job?

You are not legally required to disclose illness when applying for a job. Dutch employment law, and in particular the Medical Examinations Act (Wet op de medische keuringen, WMK) and the General Data Protection Regulation (GDPR/AVG), protects your privacy regarding medical information. Strategic transparency can sometimes be beneficial, but the choice is and always remains yours. The decision depends on your situation, the job requirements and any workplace adjustments that may be needed.
What are your legal obligations regarding illness when applying for a job?
In the Netherlands, you are not required to disclose illness or share medical information during application procedures. The Medical Examinations Act (WMK) and the GDPR protect your privacy and prohibit employers from asking questions about your health.
In principle, employers are not permitted to ask health-related questions prior to an appointment. A pre-employment medical examination is only permitted if strict conditions are met: there must be special job requirements and the examination must be carried out by an occupational physician. It is therefore not the case that an employer can simply ask whether you are able to perform certain tasks from a health perspective.
For safety-critical roles such as driver, machine operator or work involving hazardous substances, special requirements may apply. In that case, the employer can request a pre-employment medical examination. During such an examination, the occupational physician assesses whether you are suitable for the role. The employer receives only a suitability verdict, no medical details. This is an important safeguard for your privacy.
You have the right to refuse to answer medical questions that are not related to the role. Employers may not ask application questions about:
- Chronic conditions that do not affect the work
- Medication use without impact on the role
- Psychological complaints without a connection to the work
- Pregnancy or fertility
When is it wise to discuss a chronic condition?
There is no legal obligation under Dutch employment law for job applicants to disclose chronic conditions.
That said, in certain situations it can be sensible or practical to offer transparency voluntarily, not as an obligation, but as a conscious choice. This is particularly relevant when:
- You need workplace adjustments that increase your productivity
- Your condition directly affects safety or essential job performance
- Your medication affects your working hours or availability
- You expect regular absences for treatment
If in doubt, you can always ask about the exact job requirements before sharing any medical information. This way you retain control over what you do and do not disclose.
How do you deal strategically with illness during job interviews?
Dealing strategically with your health background means focusing on your capabilities rather than your limitations. Always start with what you can do and how you can function successfully. Timing is crucial: discuss health aspects only after you have demonstrated your qualities.
Effective communication strategies include:
- Starting with your strengths and relevant experience
- Explaining how you manage your condition and what you have learned from it
- Discussing what support or adjustments help you perform at your best
- Giving concrete examples of successful performance despite challenges
- Asking about possible workplace adjustments
Avoid medical jargon and focus on the practical impact. For example, say “I work best in a quiet environment” rather than going into detail about your diagnosis. Professional guidance can help you prepare for these conversations.
What are your rights as a job applicant with an illness or disability?
As a job applicant with a disability or chronic illness, you have the right to equal treatment and protection against discrimination. The Equal Treatment Act on the grounds of Disability or Chronic Illness (Wet gelijke behandeling op grond van handicap of chronische ziekte, WGBH/CZ) protects you in this regard.
Under the WGBH/CZ, employers are required to consider so-called effective adjustments for people with a disability or chronic illness, unless this involves disproportionate costs or effort. Important: this obligation applies specifically to people with a disability or chronic illness within the meaning of the law, not automatically to every form of temporary illness or recent sick leave.
Your most important rights as a job applicant:
- Privacy of medical data (protected by the GDPR and WMK)
- The right to refuse to answer irrelevant medical questions
- Equal opportunities for a job offer
- Effective workplace adjustments (for disability or chronic illness within the meaning of the WGBH/CZ)
- Protection against discrimination
In the event of discrimination, you can contact the Netherlands Institute for Human Rights (College voor de Rechten van de Mens) or seek legal assistance. Always document any discriminatory statements or behaviour during application procedures.
What are the benefits of being transparent about your health when applying for a job?
Being transparent about your health can be beneficial by helping you find a suitable working environment and preventing problems later on. Openness demonstrates professionalism, self-awareness and problem-solving ability, qualities that employers value.
Benefits of strategic openness include:
- A better match between you and the employer
- Immediate clarity about possible adjustments
- Preventing problems during the probationary period
- Demonstrating honesty and integrity
- A greater chance of finding a supportive working environment
Transparency works best when used strategically: wait until you have sparked interest, focus on solutions and show how you can contribute successfully.
