Ziektewet After Your Contract Ends
Short answer
If you become sick around the end of your contract, Dutch sickness protection does not disappear automatically. But the correct route depends heavily on timing. The first question is whether you were already ill on the last day of employment, or whether you became ill within the 4 weeks after the contract ended. Those are connected routes, but they are not identical files.
For expats, the biggest risk is delay. This is a timeline-driven benefit area, and waiting to “see how it develops” can damage the file immediately.
Who this article is for
This page is for:
- employees whose temporary contract ended while they were ill
- workers who became ill shortly after the end of employment
- people already on WW who then became sick
- readers trying to understand how Ziektewet connects to longer-term WIA questions
Start with the two date questions
Write down these dates first:
- your exact contract-end date
- your exact first sick day
Most of the route follows from those two dates. Users often remember the general story but not the actual timeline. In this area, the timeline is the story.
The first split: already sick or sick within 4 weeks
There are two main patterns:
- you were already sick when the employment ended
- you became sick within 4 weeks after the employment ended
The reason this split matters is that the reporting route, supporting documents and the role of the former employer can differ. A clean file begins by classifying which pattern you are actually in.
Why fast reporting matters so much
UWV repeatedly stresses quick reporting in this area. In practical terms, the early days matter much more than people expect. If the sickness starts after the contract ended, the route often expects action by the second sick day.
That is why “I thought I would first see whether I recover” is one of the most damaging user habits in this file.
Who still has to act after the contract ended?
A common misunderstanding is that once the contract ends, the former employer no longer matters at all. That is too simple.
Depending on the exact situation, the former employer can still be relevant for reporting or administration, and in some cases an own-risk arrangement can also matter. So do not assume the file has become fully private just because the employment relationship has ended.
If you are already on WW and then become sick
There is also an overlap route where the contract ended, WW has already started, and illness begins after that. In that situation, the sickness file usually has to be reported through the UWV route for someone already receiving WW.
This is an easy place for expats to make mistakes because they think sickness is only a side note to the unemployment file. In reality, it can change the benefit route and should be handled as a real event.
What the payment logic usually looks like
Ziektewet is benefit logic, not ordinary employer salary logic. The file therefore changes character once the employer-pay route ends or shifts. For users, the most important practical lesson is not the exact first calculation, but the fact that the income source, reporting route and supporting documents all change together.
If the illness continues, this file can later connect to WIA timing. That is why it is smart to build the file as one continuous timeline from the start.
Keep one timeline file from day one
A strong sickness-after-contract file should normally include:
- contract-end date
- first sick day
- reports made to UWV or the relevant route
- correspondence with the ex-employer where relevant
- WW documents if the case overlaps with unemployment
- medical-process documents needed for the benefit route
This prevents a later WIA or dispute file from having to be rebuilt from fragments.
Why this page often leads to WIA later
Users often think of Ziektewet after contract end as a short-term admin issue. But if illness continues, it can become part of the longer-term incapacity route. That is why the quality of the early timeline matters more than it seems.
A rushed or poorly documented start can create problems much later, when WIA timing and work-capacity questions are already under pressure.
Common mistakes
- failing to write down the exact contract-end date and first sick day
- waiting too long because you hope to recover quickly
- assuming the ex-employer can no longer matter at all
- treating sickness during WW as a minor update instead of a route change
- keeping WW, Ziektewet and medical documents in separate, unconnected files
What to do now
- Record the exact contract-end date and first sick day.
- Decide whether the case is “already sick at contract end” or “sick within 4 weeks after contract end.”
- Report through the correct route immediately.
- Check whether the ex-employer still has an administrative role in your case.
- If WW is already running, treat the sickness as a separate reporting event.
- Keep the whole file in one timeline because long-term illness can later lead into WIA.
