Dutch employment law is, by the standards of most countries expats move from, remarkably employee-protective. The idea that an employer can simply end your employment without reason, with minimal notice, and with no financial obligation — the norm in the US and not uncommon in some other countries — is not the Dutch reality. The Netherlands has a detailed framework of dismissal rules, notice periods, severance entitlements, and protections against unfair treatment that have been built up over decades.
Understanding this framework matters not only when things go wrong but at the beginning of an employment relationship. Knowing your rights during the proeftijd, understanding whether a CAO applies to your employment, and knowing what you are entitled to if your employer does not renew a contract — these are things that affect real money and real security.
This guide covers the fundamentals. For issues that require professional advice — particularly if you are facing a dismissal or dispute — an employment lawyer (arbeidsrechtadvocaat) should be consulted.
Employment Contracts in the Netherlands
Dutch employment contracts come in several forms:
Bepaalde Tijd (Fixed-Term Contract)
A bepaalde tijd contract runs for a defined period — often 6 months, 1 year, or longer. At the end of the term, the contract either expires automatically or is renewed. Under the Wet Werk en Zekerheid (WWZ), the “ketenregeling” (chain rule) applies: after 3 consecutive fixed-term contracts or after 3 years of continuous employment (whichever comes first), the employer must offer a permanent contract or end the relationship. A gap of more than 6 months between contracts resets the chain.
If your employer does not intend to renew a fixed-term contract, they must notify you at least 1 month before the contract end date (the “aanzegplicht”). Failure to do so results in a financial penalty of up to 1 month’s salary.
Onbepaalde Tijd (Permanent Contract)
An onbepaalde tijd contract has no set end date. This is the gold standard in Dutch employment — it provides the strongest legal protections and is a prerequisite for many things in Dutch life (mortgages, long-term rental contracts). Getting a permanent contract is often a significant milestone for expats who arrive on a series of fixed-term arrangements.
Oproepcontract (Zero-Hours or On-Call Contract)
Zero-hours contracts exist in the Netherlands but are more regulated than in some other countries. After 12 months, employees on zero-hours contracts have the right to a contract for a fixed number of hours based on their average worked hours in the previous year.
For a detailed breakdown of Dutch employment contracts, see our Dutch employment contract explained guide.
The Proeftijd (Trial Period)
The proeftijd allows both employer and employee to assess fit during an initial period, with simplified termination rights. The rules are specific:
| Contract Type | Maximum Proeftijd |
|---|---|
| Contract < 6 months | Not permitted |
| Contract 6 months to 2 years | 1 month maximum |
| Contract 2 years or permanent | 2 months maximum |
During the proeftijd:
- Either party can terminate without notice and without giving a reason
- Termination must still be in writing
- Termination for discriminatory reasons (pregnancy, illness, protected characteristics) is unlawful even during proeftijd
- No transitievergoeding is owed if the employer terminates during proeftijd
- If the employee terminates, they do not owe compensation
The proeftijd must be agreed in writing — typically in the employment contract itself. Verbal agreements are not legally valid.
Opzegtermijn (Notice Period)
The opzegtermijn is the notice period that must be given when terminating employment. There are different rules for employer-initiated and employee-initiated termination.
Statutory Notice Period (Employer Terminating)
| Length of Service | Statutory Employer Notice |
|---|---|
| Less than 5 years | 1 month |
| 5-10 years | 2 months |
| 10-15 years | 3 months |
| 15+ years | 4 months |
Statutory Notice Period (Employee Resigning)
The statutory notice period for an employee who resigns is 1 month regardless of tenure. This can be extended in the employment contract (but not beyond 6 months for the employee).
Important Rules
- Notice must be given in writing
- Notice counts from the end of the calendar month (unless the contract says otherwise). If you resign on January 14, your notice period starts on February 1
- The employer and employee can agree to a shorter notice period during termination, but this must be mutual and in writing
- CAO rules may specify different notice periods; these override the statutory minimum if more favourable to the employee
Dismissal Protection (Ontslagbescherming)
Dutch employment law provides strong protection against dismissal. An employer cannot simply decide to end your employment — they must follow specific procedures and demonstrate a legally recognised ground.
The Two Routes for Dismissal
Route 1: UWV (Economic or Long-Term Illness)
If the employer wants to dismiss an employee for economic reasons (bedrijfseconomische redenen — redundancy, restructuring, business closure) or because the employee has been ill for more than 2 years, they must apply to the UWV (Uitvoeringsinstituut Werknemersverzekeringen — the Dutch Employment Insurance Agency) for permission.
The UWV assesses whether the reason is genuine and whether proper procedures were followed. The process typically takes several weeks. If the UWV grants permission, the employer can then give notice (with the applicable notice period). If permission is refused, the employer cannot proceed on this ground.
Route 2: Kantonrechter (Personal Grounds)
For dismissals based on personal grounds — inadequate performance, damaged working relationship (verstoorde arbeidsverhouding), serious misconduct — the employer must apply to the kantonrechter (district court, lower civil division) to dissolve the employment contract.
The employer must demonstrate:
- A legitimate ground (one of the legally recognised grounds — the “d-grond” for functioning, “e-grond” for culpable acts, “g-grond” for breakdown of relationship, etc.)
- That appropriate steps were taken before reaching this point (warnings, performance improvement plans, mediation)
- That redeployment in another role was not possible
The kantonrechter has the power to refuse the request, grant it with standard transitievergoeding, or grant it with an additional “billijke vergoeding” (fair compensation) if the employer behaved culpably.
Protected Categories
Certain employees have enhanced dismissal protection and cannot be dismissed (or dismissal is more restricted) in specific circumstances:
- Sick employees — cannot be dismissed during the first 2 years of illness
- Pregnant employees — dismissal during pregnancy and maternity leave is prohibited
- Employees on parental leave or other statutory leave — enhanced protection during leave periods
- Employee representatives (works council members, union representatives) — specific procedural protections
- Employees close to retirement — some CAOs provide additional protections
Transitievergoeding (Statutory Severance)
The transitievergoeding is the statutory severance payment that Dutch law requires employers to pay in most termination situations.
When You Are Entitled
You are entitled to transitievergoeding if:
- Your employer terminates your employment (dismissal, end of fixed-term without renewal, dismissal via UWV or court)
- You have worked for the employer for any period (there is no minimum tenure requirement)
- The termination is at the employer’s initiative
When You Are Not Entitled
- You resign voluntarily
- You are dismissed for urgent reasons (ontslag op staande voet — instant dismissal for serious misconduct)
- You reach the Dutch state pension age (AOW-leeftijd) — transitievergoeding is not paid when employment ends at retirement age
- Termination is during the proeftijd
Calculation
The transitievergoeding is calculated as follows:
- 1/3 monthly salary per full year worked
- Plus proportional calculation for partial years
- Based on gross monthly salary including holiday allowance and fixed allowances (but excluding variable bonuses in most cases)
Maximum transitievergoeding (2026): approximately EUR 98,000 or 1 year’s salary, whichever is lower (this maximum is adjusted annually).
Example calculation:
- 4 years and 6 months of employment
- Gross monthly salary EUR 4,500 (including 8% vakantiegeld)
- Transitievergoeding: (4 × EUR 1,500) + (6/12 × EUR 1,500) = EUR 6,750
CAO: Collective Labour Agreements
A CAO (Collectieve Arbeidsovereenkomst) is a collective agreement negotiated between employer organisations and trade unions. CAOs are a fundamental feature of the Dutch labour market — approximately 80% of Dutch employees are covered by a CAO.
What a CAO Covers
CAOs typically specify, for a specific sector or company:
- Minimum salary scales by role/grade/experience level
- Annual salary increases
- Holiday entitlement (often above the statutory 20-day minimum)
- Holiday allowance (vakantiegeld, minimum 8% of gross annual salary by law; CAOs often set higher percentages or different payment arrangements)
- Pension scheme details
- Working hours
- Sick pay top-up arrangements
- Specific leave rights (parental, bereavement, etc.)
- Bonus and incentive arrangements
Finding Your CAO
If a CAO applies to your employment, your employer must tell you which one. CAOs are publicly available through the Rijksoverheid website. Major sectoral CAOs include:
- Metalelektro/Metaal — manufacturing and engineering
- Bouw — construction
- ICT — technology sector
- Zorg — healthcare
- Onderwijs — education
- Retail — retail trade
Large employers (banks, insurers, transport companies) often have their own company-level CAO rather than a sectoral one.
CAO vs Your Contract
A CAO sets minimum standards. Your individual employment contract can exceed CAO terms (give you more) but cannot fall below them. If your contract provides worse terms than the applicable CAO on any point, the CAO terms override your contract on that point.
Wet Werk en Zekerheid (WWZ) — The Legal Framework
The Wet Werk en Zekerheid (WWZ), in force since 2015, significantly reformed Dutch employment law. The key changes it introduced that still shape employment today:
- Transitievergoeding from day one — replaced the old system where severance was only paid after 2+ years
- Ketenregeling (chain rule) — maximum 3 fixed-term contracts over 3 years before permanent contract required; gap to reset the chain extended from 3 to 6 months
- Stricter dismissal grounds — the current system of specific “grounds” (a-h) for dismissal
- Aanzegplicht — employer must notify employee at least 1 month before end of fixed-term whether it will be renewed
- Transitievergoeding calculation reform — simplified to 1/3 monthly salary per year
Flexwerk: Temporary and Flex Employment
Temporary work through agencies (uitzendbureaus) is common in the Netherlands. The flex employment rules provide some protection:
Phase system for agency workers:
- Phase A (first 78 weeks): Minimal protection; agency can terminate at will when client has no work
- Phase B (weeks 79+): Fixed-term contracts with an agency; transitievergoeding applies
- Phase C (after Phase B): Agency must offer a permanent contract or agency employment ends
The Dutch government has been progressively tightening flex employment rules to reduce the use of flex work as a way to avoid providing permanent contracts. Recent reforms (Wet toelating terbeschikkingstelling van arbeidskrachten, incoming 2025-2026) introduce certification requirements for agencies and increase employer penalties.
Vakbonden: Trade Unions in the Netherlands
Dutch trade union membership has declined over decades but unions remain influential in setting CAOs. The main umbrella organisations:
- FNV (Federatie Nederlandse Vakbeweging) — the largest Dutch union federation; covers many sectors
- CNV (Christelijk Nationaal Vakverbond) — Christian-aligned union federation
- VCP (Vakcentrale voor Professionals) — focused on higher-educated professionals and managers
For most expats, individual trade union membership is more useful as legal protection than as collective bargaining participation. Many unions offer legal assistance for employment disputes as a membership benefit — this can be valuable if you face a dismissal or contract dispute.
If You Are Fired: What to Do Step by Step
Immediate Steps
Do not sign anything immediately. You are not legally required to sign a settlement agreement (vaststellingsovereenkomst) at the moment of notification. Take time to review it carefully.
Get the notification in writing. Ask for written confirmation of the termination, the reason given, and the proposed timeline.
Check whether the proeftijd had expired. If you are being dismissed and your proeftijd was still running, the employer has wider rights but must still dismiss in writing.
Identify the dismissal ground. Is this economic (UWV route)? Is it a court application? Is it instant dismissal (ontslag op staande voet)? The route matters for your rights.
If You Receive a Vaststellingsovereenkomst (Settlement Agreement)
A vaststellingsovereenkomst (VSO) is a mutually agreed termination — often called “ontslag met wederzijds goedvinden.” It is common and can be perfectly acceptable if the terms are right. Key things to check:
- Is the transitievergoeding correctly calculated (or is a higher “billijke vergoeding” appropriate given the circumstances)?
- Is there a “non-compete” clause (concurrentiebeding) and is it reasonable?
- Does the settlement specify that the termination is “via wederzijds goedvinden” and not your resignation? This phrasing matters for WW eligibility.
- Is the end date correct given applicable notice periods?
Get legal review before signing. An employment lawyer consultation for VSO review typically costs EUR 200-500 and can be well worth it.
Registering for WW (Unemployment Benefit)
If you are made redundant or your fixed-term contract is not renewed, you may be entitled to WW (Werkloosheidswet — unemployment benefit) from the UWV.
Requirements:
- You must have worked at least 26 weeks out of the 36 weeks before your unemployment
- You must be available and actively seeking work
- Your unemployment must not be your fault (you must not have resigned or been dismissed for urgent reasons)
- You must register with the UWV within 1 week of your last working day
WW benefit is calculated at 75% of your last daily wage in the first 2 months, then 70%. The duration of WW depends on your employment history — minimum 3 months, maximum 24 months.
Salary Negotiation and Your Rights
For expats negotiating employment in the Netherlands, understanding market rates and legal minimums is important. The Wet minimumloon sets a statutory minimum wage; as of January 2025, this is approximately EUR 13.68/hour (regularly updated). Most professional roles pay well above this.
The Netherlands does not have a general statutory right to annual salary increases, but many CAOs mandate specific increases. In a tight labour market, salary negotiation is accepted and expected — see our salary negotiation guide for expats.

Dutch employment law tilts toward protecting the employee more than most systems expats will have encountered. The proeftijd is limited and defined. Dismissal requires procedure and justification. Severance is statutory and calculated by formula, not negotiated from scratch. If you are in employment in the Netherlands, knowing these rules does not require paranoia — it requires the same basic literacy that makes you a competent participant in any employment relationship.
If you face a dismissal or significant employment dispute, the investment in a one-hour consultation with an employment lawyer is almost always worth making. The stakes are high enough and the rules detailed enough that professional advice is the right approach.
Frequently Asked Questions
How long is the trial period (proeftijd) in the Netherlands?
The proeftijd (trial period) in the Netherlands is limited by law. For contracts of 6 months to 2 years, the maximum trial period is 1 month. For contracts of 2 years or more, the maximum is 2 months. For temporary contracts shorter than 6 months, a trial period is not legally permitted at all. During the proeftijd, either party can terminate the employment without notice and without reason — though terminating for discriminatory reasons is still unlawful. A trial period must be agreed in writing in the employment contract. Verbal trial periods are not legally valid.
What is the notice period (opzegtermijn) in the Netherlands?
The statutory notice period for employers in the Netherlands is based on the employee’s length of service: up to 5 years = 1 month notice; 5-10 years = 2 months; 10-15 years = 3 months; 15+ years = 4 months. Employees typically have a 1-month notice period regardless of tenure, unless the employment contract specifies otherwise. CAO (collective labour agreement) rules may override statutory minimums. Notice must be given in writing and counts from the end of the calendar month unless the contract states otherwise. Notice periods can be agreed longer in the employment contract but not shorter than the statutory minimum.
What is a transitievergoeding and am I entitled to one?
A transitievergoeding is statutory severance pay that you are entitled to in most cases when your employer terminates your employment or does not renew a fixed-term contract. The amount is 1/3 of a monthly salary for each full year worked, plus a proportional amount for partial years. There is no minimum service period required — you are entitled to transitievergoeding from day one (though in practice the amount for very short tenure is small). The maximum transitievergoeding in 2026 is approximately EUR 98,000 or one year’s salary (whichever is lower). You are not entitled to transitievergoeding if you resign voluntarily, if you are dismissed for urgent reasons (ontslag op staande voet), or if you have reached retirement age.
What is a CAO and does it apply to me?
A CAO (Collectieve Arbeidsovereenkomst) is a collective labour agreement negotiated between employers (or employer associations) and trade unions. CAOs set minimum standards for wages, working hours, holiday entitlement, pension contributions, and other employment conditions in a specific sector or at a specific company. If your employer is bound by a CAO relevant to your sector, those terms apply to your employment — often providing better conditions than the statutory minimum. Your employer must inform you which CAO (if any) applies to your employment. CAOs are publicly available; the key terms are often summarised in your employment contract.
How strong is dismissal protection in the Netherlands?
Very strong. Dutch employment law provides substantial protection against unfair dismissal (onrechtmatig ontslag). An employer cannot simply terminate your employment because they want to. Dismissal requires a legally recognised ground: economic reasons (UWV route), personal functioning issues (kantonrechter route), or other specific grounds. The process has mandatory steps: a performance improvement period for functioning issues, consultation with UWV or court involvement for economic dismissals. Even when dismissal is justified, the employer typically owes a transitievergoeding. Employers who dismiss employees without proper grounds risk being ordered to reinstate the employee or pay a fair compensation (billijke vergoeding) on top of the transitievergoeding.
What should I do if I am fired in the Netherlands?
First, do not sign anything immediately. You typically have time to consider your options. Second, check whether proper procedure was followed — was the correct dismissal route used? Was your proeftijd over? Were you warned and given opportunity to improve? Third, consider whether to engage a lawyer (arbeidsrechtadvocaat) to review the situation. Legal aid (rechtsbijstand) may be available if you have insurance. Fourth, check your transitievergoeding calculation — employers sometimes get this wrong. Fifth, register with the UWV (the Dutch employment agency) as soon as possible to preserve your right to WW (unemployment benefit). You have 26 weeks of employment history required to claim WW.
What are my rights regarding holiday and sick leave in the Netherlands?
Holiday: the statutory minimum is 4 times your weekly working hours per year — for full-time employees (5 days/week), this is 20 days. Most Dutch employment contracts and CAOs provide 25 days. Unused holiday entitlement accumulates and must be paid out on termination. Sick leave: you are entitled to at least 70% of your salary during the first 2 years of illness — most employers pay 100% in the first year. Your employer cannot dismiss you during the first 2 years of illness (the ‘opzijgingsverbod’). After 2 years of illness, a dismissal process may begin.
