Sleeping employment contracts in the Netherlands remain legally active after the mandatory 104-week wage payment period for employee illness. Conflicting court rulings create unpredictable financial exposure for expat entrepreneurs. One court denies vacation pay accumulation (Noord-Nederland, December 2025), while another awards €13,149.74 for accumulated vacation days (Gelderland, August 2025). Without proper documentation at the 104-week decision point, micro-employers face escalating liability from vacation claims, transition payments, and settlement costs.
Core Facts:
- Sleeping contracts (slapend dienstverband) persist after 104 weeks of illness-related wage payments end
- Two 2025 Dutch court rulings directly contradict each other on vacation pay rights during dormancy
- The 104-week mark is a critical decision point where employers must document termination rationale or reintegration prospects
- EU law (Directive 2003/88/EG) conflicts with Dutch Civil Code Article 7:634 on vacation accrual without wages
- Supreme Court’s 2022 Xella ruling: maintaining sleeping contracts only to avoid severance violates good employment practice
Your employment contract technically remains active after two years of wage payments for employee illness. No work happens. No salary flows. But the legal relationship persists.
Most expat entrepreneurs in the Netherlands assume these slapend dienstverband (sleeping contracts) fade into administrative background noise.
They don’t.
Recent court rulings reveal a mechanism that transforms administrative ambiguity into financial exposure. The system doesn’t measure your intentions. It measures what you prove.
What Are Sleeping Employment Contracts in the Netherlands?
A sleeping employment contract (slapend dienstverband) is an employment relationship that remains legally active after the employer’s mandatory 104-week wage payment obligation for employee illness ends.
During this dormant period, no work occurs and no salary is paid. But the employment contract persists unless formally terminated.
This creates ongoing legal obligations and potential financial exposure that most expat entrepreneurs underestimate.
Bottom line: Sleeping contracts create legal obligations without operational activity, turning administrative inaction into measurable risk.
Why Two 2025 Court Rulings Create Impossible Choices
On December 19, 2025, the District Court of Noord-Nederland ruled that employees with sleeping contracts have no right to vacation pay accumulation after the two-year wage payment period ends.
The logic: vacation with pay retention cannot exist without actual pay entitlement. The court rejected a claim for 283.5 hours of unused vacation time.
Four months earlier, on August 12, 2025, the Gelderland District Court ruled the exact opposite.
In the Wega case, a welder employed since 1995 became fully incapacitated after a 2019 motorcycle accident. The employer refused to terminate the sleeping contract or pay accumulated vacation days.
The court ordered the employer to pay €13,149.74 gross for accumulated vacation hours during the dormant period. The ruling stated that EU law requires vacation accrual regardless of wage entitlement.
This creates a situation where business owners must simultaneously prepare for contradictory legal outcomes. Your exposure depends on which court hears your case.
Bottom line: Two authoritative Dutch courts reached opposite conclusions on the same legal question within four months, making compliance impossible to predict.
How Dutch Law Conflicts With EU Employment Protections
The legal collision happens at the jurisdictional level:
Dutch Civil Code Article 7:634 explicitly states that vacation accrual depends on wage entitlement. No wages equals no vacation accumulation.
EU Directive 2003/88/EG (Working Time Directive) and European Court of Justice rulings tie vacation rights to the employment relationship itself, not wage payment.
According to EU law, vacation serves purposes of rest, relaxation, and free time that national laws cannot circumvent.
The Netherlands has not amended its legislation despite this conflict. Dutch courts now choose between domestic law and EU supremacy on a case-by-case basis.
For micro-employers, this means you cannot rely on following the rules when the rules contradict each other at the source level.
Bottom line: The legal foundation splits between Dutch national law and EU supremacy, forcing courts to choose and creating unpredictable outcomes for employers.
Why the 104-Week Mark Is a Critical Decision Point
After 104 weeks of employee illness, both the wage payment obligation and the dismissal prohibition end in Dutch law. This creates a natural decision point.
At this moment, you have two options:
- Request UWV dismissal permission
- Offer a termination agreement
Many employers chose to keep contracts sleeping to avoid transition payments. That financial incentive disappeared in 2020.
The Compensation Scheme allows employers to reclaim transition payments for long-term illness dismissals. Yet the administrative habit of maintaining dormant contracts persisted in many organizations.
What the Supreme Court’s 2022 Xella Ruling Changed
The Supreme Court’s 2022 Xella judgment clarified the stakes.
Employers are obligated to agree to employee proposals for contract termination with severance payment once the 104-week illness period expires, provided there are no genuine reintegration prospects.
The court determined that maintaining sleeping contracts solely to avoid transition payments violates good employment practice (goed werkgeverschap). This principle applies from July 20, 2018 onward.
Employers who miss this natural decision point face escalating exposure. Vacation days potentially continue accumulating and transition payments grow with contract duration.
Bottom line: The 104-week mark requires a documented decision with clear rationale, because keeping contracts dormant without reintegration prospects violates Dutch employment law principles.
How Dormancy Destroys Normal Documentation Practices
When employment relationships become dormant, the natural feedback loops that prevent disputes disappear.
There are no performance reviews. No ongoing conversations. No shared understanding of mutual expectations.
Courts recognize this reality. The Gelderland court noted that during dormant employment, neither the employer nor employee expect the worker to return to the organization.
This makes contemporaneous documentation of decision rationale, reintegration assessments, and communication attempts critical.
Memories fade. Reconstructing intent becomes impossible when settlement discussions begin years later.
You need heightened documentation standards precisely when interaction is absent.
Bottom line: Dormant contracts eliminate the operational feedback that normally prevents disputes, making proactive documentation your only protection against retroactive claims.
What Controls Should You Install for Sleeping Contracts?
Install these controls before administrative drift becomes financial liability:
1. Document the 104-Week Decision Explicitly
Record why you chose to maintain or terminate the contract at the natural break point. Include reintegration assessment, medical prognosis, and business impact analysis. Date and sign it.
2. Create a Dormant Contract Review Calendar
Set quarterly reviews for any contract that remains sleeping past 104 weeks. Document each review: what changed, what you assessed, what you decided, why.
3. Separate Vacation Accrual Tracking From Wage Administration
Even if you believe Dutch law applies, track vacation hours separately as a contingent liability. If a court applies EU law retroactively, you’ll have the calculation ready.
4. Maintain Communication Logs
Every attempt to contact the employee, every reintegration discussion, every medical update needs to be logged with dates and outcomes. Silence looks like neglect in court.
5. Prepare Transition Payment Calculations in Advance
Know the cost of termination at any moment. Compare it to the cost of maintaining dormancy plus potential vacation accumulation. Update this quarterly.
6. Consult Before the Dispute Starts
The moment you sense settlement pressure or legal positioning from the employee side, engage professional guidance. Reactive consultation costs more than preventive structure.
Bottom line: Administrative controls installed before disputes arise cost less than legal defense after claims surface.
What This Signals About Regulatory Risk for Micro-Employers
The conflict between Dutch national law and EU employment protections signals broader jurisdictional tensions.
As European labor regulation becomes more prescriptive, micro-employers face compliance environments where following the rules requires choosing between contradictory authoritative sources.
This fundamentally alters the relationship between business scale and regulatory risk. Small companies historically benefited from regulatory simplicity. That advantage is eroding.
The system no longer rewards good intentions or reasonable assumptions. It measures proof, structure, and documentation discipline.
Sleeping contracts expose this shift clearly. The administrative choice to do nothing transforms into legal exposure measured in vacation hours, transition payments, and settlement costs.
Structure is cheaper than recovery.
Bottom line: Regulatory complexity once reserved for large corporations now applies equally to micro-employers, eliminating the historical advantage of business simplicity.
Frequently Asked Questions
What happens to an employment contract after 104 weeks of employee illness in the Netherlands?
After 104 weeks (two years) of employee illness, the employer’s wage payment obligation ends and the dismissal prohibition lifts. The employment contract does not automatically terminate. It becomes a sleeping contract (slapend dienstverband) unless the employer formally terminates it through UWV dismissal permission or a termination agreement.
Do employees accumulate vacation days during sleeping contracts?
This is legally uncertain. Dutch Civil Code Article 7:634 states vacation accrual requires wage entitlement, suggesting no accumulation during dormancy. But EU Directive 2003/88/EG ties vacation rights to the employment relationship itself. Two 2025 Dutch court rulings reached opposite conclusions. The Gelderland court awarded €13,149.74 for accumulated vacation, while the Noord-Nederland court denied 283.5 hours of vacation claims.
Why would an employer keep a sleeping contract instead of terminating it?
Before 2020, employers avoided transition payments by maintaining sleeping contracts. That financial incentive ended when the Compensation Scheme allowed employers to reclaim transition payments for long-term illness dismissals. The Supreme Court’s 2022 Xella ruling confirmed that maintaining sleeping contracts solely to avoid severance violates good employment practice (goed werkgeverschap).
What documentation should employers maintain for sleeping contracts?
Employers should document the 104-week decision with clear rationale, conduct quarterly reviews with written assessments, track vacation hours separately as contingent liability, maintain communication logs for all employee contact attempts, and prepare updated transition payment calculations. This documentation protects against retroactive claims when normal operational feedback is absent.
When should an employer terminate a sleeping contract?
Termination should occur at the 104-week mark unless genuine reintegration prospects exist. Employers must document medical prognosis, reintegration assessment, and business impact analysis. Keeping contracts dormant without legitimate reintegration prospects exposes employers to vacation accumulation claims, growing transition payments, and potential violations of good employment practice.
What is the financial risk of mismanaging sleeping contracts?
Financial exposure includes accumulated vacation pay (potentially thousands of euros as shown in the €13,149.74 Wega case), transition payments that grow with contract duration, settlement costs during disputes, and legal fees. The conflicting court rulings mean employers must prepare for worst-case scenarios from multiple contradictory precedents simultaneously.
How does EU law conflict with Dutch law on sleeping contracts?
Dutch Civil Code Article 7:634 links vacation accrual to wage entitlement. EU Directive 2003/88/EG links vacation rights to the employment relationship itself, regardless of wages. The Netherlands has not amended its legislation to resolve this conflict. Dutch courts choose between domestic law and EU supremacy case by case, creating unpredictable outcomes for employers.
What is the Xella ruling and why does it matter?
The Supreme Court’s 2022 Xella judgment established that employers must agree to employee proposals for contract termination with severance once the 104-week illness period expires if no genuine reintegration prospects exist. Maintaining sleeping contracts solely to avoid transition payments violates good employment practice. This principle applies retroactively from July 20, 2018 onward.
