Your employer can request a declaration of work capacity (formerly known as a medical certificate) in the event of a prolonged illness. It is your employer’s responsibility to pay for the declaration of work capacity. The purpose of this declaration is to assess how you can continue to perform relevant work tasks in the future without worsening your health. You are required to submit a declaration of work capacity and attend a meeting if your employer requests it, as long as your health allows.

One part of the declaration of work capacity must be filled out and signed by both you and your employer. The other part is completed with your doctor and then given to your employer.

If you're unsure about what to do if you experience a prolonged illness, you can always contact your local 3F branch for guidance.

• Always check the company's rules for documentationm so you are prepared if you happen to get sick. Ask your union representative for help if needed.
• You are not required to tell your employer what your illness is. It is enough to say that you are ill.
• Make sure to submit declarations within the deadline.
• Contact your local 3F branch if your employer demands more medical certificates than the rules require.

• Fill out and sign the first half of the declaration of work capacity together with your manager. Describe the tasks you may have difficulty performing and suggest how your work duties could be adjusted to accommodate your current situation.
• Next, take the declaration of work capacity to your doctor. Based on your health, your doctor will assess whether the suggested tasks and the number of hours you can work per week are realistic. The doctor will also estimate how long you are likely to be ill.
• Submit the declaration of work capacity to your employer as soon as your doctor has completed it, and no later than 14 days after you and your employer signed the first part.
• If you work while on sick leave, it is called a partial return to work.
• Your employer is responsible for paying for the declaration of work capacity.
