Stopping work earlier during pregnancy: sickness, adjustments or maternity leave?

Stopping work earlier during pregnancy: sickness, adjustments or maternity leave?

Needing to stop work earlier can mean different things: choosing maternity leave, being medically unable to work or needing safer duties. Each route has different consequences. This guide helps you organise the dates, work difficulties and questions for the occupational physician, employer and UWV without diagnosing your own condition.

Discuss concrete limitations, adjustments and any sickness report with the employer and occupational physician. Wanting leave and being medically unfit are different situations.

If leave has not started, sickness in the flexible start window can reduce the days remaining after birth. Ask for the calendar to be checked.

Illness during maternity leave that has already started does not normally create additional leave days.

1. Identify why you need to stop earlier

Wanting more time off, being medically unfit and needing adjustments to unsafe work are different situations. If the issue is a preference for an earlier break, examine the statutory start window and any separate leave agreement. If symptoms or workplace risks are involved, explain the actual tasks, hours and conditions causing difficulty. You do not need to make a final medical or legal classification yourself.

Record concrete examples: prolonged standing, lifting, night shifts or being unable to take necessary rest. Note adjustments already tried and why they were insufficient. This helps the occupational physician assess functional limitations. An employer mainly needs practical information about implementing work arrangements. Sharing a full diagnosis with everyone involved in scheduling is generally different from providing the medical professional with information needed for assessment.

2. Treat work adjustments as a separate route

Employers must take account of protections for pregnant and recently pregnant workers. Appropriate adjustments depend on duties and risks. Ask for a specific discussion of tasks, breaks and scheduling, with a start date, a person responsible for implementation and a review moment. A verbal agreement may not work in practice if the person preparing the next roster knows nothing about it.

You may be able to continue some duties, or an occupational assessment may be needed. Ask under which conditions work is possible rather than only whether you can work at all. The existing [night-work dossier](guide:nachtwerk) covers an additional relevant area. Moving maternity leave earlier does not automatically resolve workplace safety questions for the period before the statutory leave window begins.

3. Sickness before the flexible start window

If illness begins before the statutory choice period, follow the sickness reporting procedure and discuss medical assessment with the occupational physician. For illness caused by pregnancy or childbirth, an employer may apply for sickness benefit. UWV describes that benefit as 100% of the daily wage, subject to the applicable limit. Your pay entitlement and payroll treatment still need to be checked in context.

The employer's administrative reimbursement and your ability to work are separate questions. An application does not remove medical restrictions. Check the sickness date, proposed duties and route used, and keep arrangements for partial work. If illness is unrelated to pregnancy, other rules may apply. Raise the causal question with the appropriate professional rather than assuming all illness during pregnancy receives identical treatment.

4. Pay attention to the six-to-four-week window

For a singleton pregnancy, the flexible start window runs from six to four weeks before the day after the expected birth date. If you intended to keep working until four weeks before that date but become sick in the window, those sickness days are not simply saved as additional leave after birth. UWV explains that this can also apply to illness unrelated to pregnancy.

For twins or other multiple pregnancies, the window runs from ten to eight weeks. Record the expected date, original leave start, first sickness date and actual sick days in the relevant window. Ask for the remaining post-birth leave to be recalculated. Keeping the original later start in a team calendar does not itself prevent sickness days from affecting the calculation. Check the updated end date in writing.

Illustrative example

An employee chooses to start leave four weeks before the due date, then becomes sick in the preceding week. The planned twelve weeks after birth need checking again. Retaining the original leave entry in a calendar is insufficient. This fictional example illustrates administration, not a medical assessment.

5. Illness during leave that has already started

Illness during maternity leave does not automatically generate replacement leave days. The existing maternity benefit normally continues. Report what the employer's procedure requires and discuss practical consequences, but do not import an annual-holiday rule without checking whether it applies. Being ill during statutory maternity leave is not the same legal situation as being ill while taking ordinary annual leave.

With flexible post-birth leave, the UWV benefit may have ended even though some agreed leave hours remain. The benefit calendar and work roster can then differ. It matters whether the benefit is still running when sickness occurs. Keep both the UWV decision and flexible-leave agreement, and ask HR or UWV to identify the relevant situation before assuming that a new sickness benefit will be paid.

6. Sickness immediately after the benefit ends

If pregnancy or childbirth prevents you working on the first day after the benefit ends, report sickness promptly. UWV distinguishes illness immediately following the benefit from illness starting later. It also distinguishes a pregnancy-related cause from another cause. Saying only that you are sick after giving birth does not provide enough information to identify the correct administrative route.

Discuss medical details with the occupational physician and provide the necessary reporting information through the proper procedure. If employment ended during leave, direct contact with UWV may be relevant. The original return date in a staffing calendar does not settle the matter; the current benefit dates and actual medical circumstances are needed. Individual legal help may be appropriate where pay or suitable work is disputed.

7. Prepare one timeline and keep medical records separate

Record the expected date, chosen leave start, sickness reports, days actually worked or sick and the final leave end. Add work arrangements and relevant payslips. Keep medical material for the medical recipient. If you dispute a calculation, identify the days you believe were handled incorrectly and the confirmation you received, rather than presenting only an overall number of missing weeks.

Request a written explanation of both the leave calendar and income route. An answer that you receive 100% does not establish the end date, daily-wage ceiling or employer supplement. Use [leave duration](guide:duur-bevallingsverlof) for calendar questions and [benefit amount](guide:hoogte-zwangerschapsuitkering) for financial checks. A clear factual account helps even when you cannot personally classify the medical cause under the relevant legislation.

Describe concrete duties, risks and limitations for discussion.

Discuss work capacity and medical questions with the occupational physician.

Record sickness and the chosen leave start separately.

Request confirmation of remaining leave and the applicable income route.

Can I stop earlier because work is too difficult?

Discuss concrete limitations, adjustments and any sickness report with the employer and occupational physician. Wanting leave and being medically unfit are different situations.

What if I become sick five weeks before the due date?

If leave has not started, sickness in the flexible start window can reduce the days remaining after birth. Ask for the calendar to be checked.

Does sickness during WAZO give extra leave?

Illness during maternity leave that has already started does not normally create additional leave days.

Must I provide my employer with my medical file?

Discuss medical assessment with the occupational physician and provide necessary reporting and work-arrangement information through the appropriate procedure.
