Dutch employment law compliance: seven common employer mistakes

Dutch employment law compliance goes wrong most often on seven points: template contracts that ignore mandatory Dutch rules, fixed-term chains, working time and minimum wage, holiday and leave, sickness and reintegration, records and employee data, and the end of the employment relationship. Almost all of these rules are mandatory law, so a clause that conflicts with them is void, whatever law the contract chooses.

The floor is set by the Dutch Civil Code (Burgerlijk Wetboek, BW), the Working Hours Act (Arbeidstijdenwet), the Working Conditions Act (Arbeidsomstandighedenwet) and any applicable collective agreement (collectieve arbeidsovereenkomst, cao). That floor applies from the first working day. Below we set out the seven typical mistakes, what the law requires and how you put each one right.

Why does a template contract so often fail under Dutch law?

Because Dutch mandatory law applies to work performed in the Netherlands, whatever the contract says. A translated international template usually breaks the rules on probation, notice and non-competition.

If the work is performed in the Netherlands, the mandatory provisions of Dutch employment law and any generally binding collective agreement apply, whatever law the parties chose. The contract then looks complete but is unenforceable exactly where it matters.

The first trap is the probationary period (proeftijd). Under Article 7:652 BW it must be agreed in writing and be the same for both parties. There is no probation in a contract of six months or less, a maximum of one month in a fixed-term contract of less than two years, and a maximum of two months in a longer fixed-term or an indefinite contract. A clause that exceeds the limit is void in its entirety; it is not reduced to the maximum.

The second trap is the notice period. Under Article 7:672 BW the statutory notice period for the employer runs from one to four months, depending on length of service; the employee owes one month. If the employee’s notice period is extended in writing, the employer’s notice period must be at least double that of the employee.

The third is the non-competition clause (concurrentiebeding). Article 7:653 BW requires it to be agreed in writing with an adult employee. In a fixed-term contract it is only valid if the clause itself sets out the compelling business interests that make it necessary. A collective agreement for your sector can also override your contract on pay scales, working hours, allowances and pensions.

An example to illustrate: a foreign company opens a Dutch office and uses its group template for a one-year contract with three months’ probation. Under Article 7:652 BW the probation clause is void, because one month is the maximum. If the company ends the contract in month two relying on probation, it has in fact given notice without a valid ground or permission.

How do you keep fixed-term contracts and the chain rule under control?

Count every contract in the chain and diarise every end date. A miscount turns a temporary employee into a permanent one, and a missed notification costs you a month’s salary.

Under the chain rule in Article 7:668a BW, a contract is deemed to be for an indefinite period once successive fixed-term contracts exceed three years, or as soon as a fourth contract is entered into. Contracts count as successive if the gap between them is six months or less. You can then only dismiss with the permission of the Employee Insurance Agency (UWV) or through the subdistrict court (kantonrechter).

Under the notification duty (aanzegplicht) in Article 7:668 BW, for every fixed-term contract of six months or more, you must inform the employee in writing no later than one month before the end date whether the contract will be continued and on what terms. If you forget, the employee is entitled to one month’s salary; if you notify late, the compensation is pro rata.

The bill on greater security for flexible workers (Wet meer zekerheid flexwerkers) proposes a longer interruption before a new chain can start; it has not entered into force, and parts are planned for 2027 and 2028 at the earliest. Until then the six-month interruption applies. For on-call workers, Article 7:628a BW already lets an employee called up with less than four days’ notice refuse the call.

Can you agree working time, minimum wage and overtime in the contract?

Only within the limits of public law. The Working Hours Act and the minimum wage rules apply whatever you and the employee agree.

The Working Hours Act caps a shift at twelve hours and a working week at sixty hours, with an average of no more than forty-eight hours a week over any sixteen weeks. An employee is entitled to at least eleven consecutive hours of rest in each 24 hours and thirty-six hours in each seven days. A shift of more than five and a half hours requires a break of at least thirty minutes; more than ten hours, at least forty-five minutes.

You must keep records of working and rest times, and the Netherlands Labour Authority (Nederlandse Arbeidsinspectie) can fine you where they are missing. The Act does not set overtime pay: that follows from the contract or collective agreement. But total pay divided by the hours actually worked may never fall below the statutory minimum hourly wage, which applies to all employees since 1 January 2024 and is revised on 1 January and 1 July.

On top of salary, the Minimum Wage and Minimum Holiday Allowance Act (Wet minimumloon en minimumvakantiebijslag) entitles the employee to holiday allowance of at least eight per cent of the gross annual salary, normally paid in May.

What goes wrong with holiday and leave entitlement?

Employers mix up statutory and contractual days and forget to warn staff about expiry. Leave under the Work and Care Act is also often missing from the records.

Under Article 7:634 BW the statutory holiday entitlement is four times the agreed weekly working hours per year: twenty days for a five-day week. Statutory days lapse six months after the end of the year in which they were accrued, unless the employee was reasonably unable to take them; contractual days are subject to a five-year limitation period. An employer that never tells staff about the expiry date will usually not be able to rely on it.

Under Article 7:638 BW you must enable the employee to take at least two uninterrupted weeks of holiday, or twice one week, each year. Employees also keep accruing holiday during sickness, which regularly surprises employers after a two-year absence.

The Work and Care Act (Wet arbeid en zorg) provides pregnancy and maternity leave of at least sixteen weeks. The partner has one week of paid birth leave, followed by up to five weeks of additional birth leave in the first six months at seventy per cent of the daily wage, paid by UWV. Parental leave is twenty-six times the weekly hours until the child turns eight; nine weeks are paid at seventy per cent if taken in the child’s first year. Record all of it in your payroll administration, or it will be claimed at the end of the employment.

What does sickness and reintegration require from you as an employer?

Up to two years of continued pay and a fixed reintegration procedure. If UWV finds your efforts insufficient, you can be ordered to keep paying for up to another year.

Under Article 7:629 BW you must continue to pay at least seventy per cent of the wage for a maximum of 104 weeks, and in the first 52 weeks not less than the statutory minimum wage. A collective agreement often raises this percentage. During those two years the prohibition on termination in Article 7:670 BW applies, so a dismissal for another reason is tested strictly.

The procedure comes from the Gatekeeper Improvement Act (Wet verbetering poortwachter). The company doctor draws up a problem analysis around the sixth week of absence, employer and employee agree a plan of action by the eighth week, and they take stock at the end of the first year. If UWV finds insufficient reintegration efforts after two years, it can extend the obligation to pay wages by up to 52 weeks. You need a basic contract with a certified occupational health service, and either party can ask UWV for an expert opinion (deskundigenoordeel).

Why do records and employee data matter so much?

Because the employer usually has to prove what it did, and privacy law sets strict rules on what you keep and for how long. A thin file is a losing position before UWV or the subdistrict court.

Before the first working day, you must establish the employee’s identity from an original valid identity document and keep a copy in the payroll administration; a driving licence does not qualify. Payroll data, including that copy, must be kept for five years after the end of the employment. Payroll and tax records also fall under the seven-year retention obligation in the General Tax Act (Algemene wet inzake rijksbelastingen).

The General Data Protection Regulation (GDPR, in Dutch AVG) requires a lawful basis for every processing operation, a record of processing activities, clear information to staff and appropriate security. A data breach that is likely to pose a risk must be reported to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) within 72 hours. Consent is rarely a valid basis in an employment relationship, and employee monitoring requires the consent of the works council under Article 27 of the Works Councils Act (Wet op de ondernemingsraden).

How do you end an employment relationship without improvising?

Choose the dismissal ground first, then the route that goes with it, and only then act. Each ground in Article 7:669 BW has its own route and its own evidence.

You must show that one ground is completely fulfilled and that redeployment in another suitable position within a reasonable period is not possible. Dismissal for business-economic reasons, or after two years of incapacity for work, runs through UWV. All other grounds, such as unsuitability, culpable conduct or a disturbed working relationship, run through the subdistrict court.

Two mistakes recur. Dismissal for unsuitability requires that the employee was told in good time, given a genuine opportunity to improve and supported; a court that sees only a final assessment will refuse the request. Summary dismissal (ontslag op staande voet) under Article 7:677 BW requires an urgent cause and immediate action; an employer that investigates for weeks risks that the dismissal will not stand.

The transition payment (transitievergoeding) under Article 7:673 BW is due on termination at the employer’s initiative, from the first day of employment, so also after dismissal during probation. In 2026 it is capped at €102,000 or one annual salary if higher. Where the employer acted seriously culpably, the court can add a fair compensation (billijke vergoeding). If you end the contract with a settlement agreement (vaststellingsovereenkomst), the employee has fourteen days to reverse it in writing without giving reasons.

What should you check as an employer?

Treat compliance as a review cycle, not a one-off project. Work through these points at least once a year and before every dismissal.

• Check the probation, notice and non-competition clauses in every contract in use against Articles 7:652, 7:672 and 7:653 BW and your sector’s collective agreement.
• Map every fixed-term contract with its end date, its position in the chain and the one-month notification deadline.
• Check that working and rest times are recorded and that pay per hour worked meets the current statutory minimum hourly wage.
• Keep holiday and leave balances in the payroll system and warn staff in writing before statutory days lapse.
• Keep one file per employee with the contract, ID copy, assessments, warnings and reintegration documents, and a retention schedule.
• Announce no termination before the ground, the route and the file have been checked.

What should you check as an employee?

As an employee in the Netherlands you can rely on these rules, even if your contract says otherwise. Check the following points.

• Is your probation period longer than Article 7:652 BW allows? Then it is void.
• Did you receive written notice at least one month before your fixed-term contract ended?
• Does your pay divided by the hours you actually worked reach the statutory minimum hourly wage?
• Has your employer told you when your statutory holiday days expire?
• On dismissal: which ground in Article 7:669 BW is used, and has your transition payment been calculated?
