Your Dutch employment contract is more than a formality — it defines your income, job security, and freedom to move between roles in the Netherlands. For expats, it can be hard to know which clauses are standard and which are risky. This 2026 guide breaks down the five contract clauses that matter most: probation, non-compete, notice period, termination, and benefits. You will see what the law requires, what employers often try to add, and which points are worth negotiating before you sign.

At a glance: 5 clauses to check before you sign
- Probation period: Only allowed if the contract is longer than 6 months, with a maximum of 1 or 2 months depending on contract length.
- Non-compete clause: Usually only valid in permanent contracts; from 2025, max 1 year with mandatory compensation when enforced.
- Notice period: Default is 1 month for employees; employers have 1–4 months depending on years of service.
- Termination and dismissal: Employers need a legal ground and must follow UWV or court procedure, even after probation.
- Benefits and minimums: Check salary against minimum wage, vakantiegeld, holiday days, and any CAO that gives extra rights.
This guide focuses on three of the most important clauses — probation, non-compete, and notice period — which together have the biggest impact on your mobility and protection under Dutch law.
1. Probationary Period: Your Mutual Trial Run
Proeftijd (probation period): A short initial phase at the start of your contract where both you and your employer can end the contract immediately without notice and without giving reasons — but only if the clause is valid and complies with strict legal rules.
The probationary period is often the first substantive clause you will encounter in a Dutch employment contract. Under Article 7:652 of the Dutch Civil Code, this clause must meet specific requirements to be valid.
Legal requirements and maximum duration
A probationary period is never automatic in the Netherlands — it must be explicitly agreed in writing. If it is not written down, or if it exceeds legal limits, the entire probation clause is invalid and your employment is treated as if there were no trial period at all.
The maximum duration depends on the contract type:
- Contracts of 6 months or less: No probation allowed.
- Fixed-term contracts longer than 6 months but less than 2 years: Maximum 1 month.
- Permanent contracts (onbepaalde tijd) or fixed-term contracts of 2 years or more: Maximum 2 months.
Any probation period that exceeds these limits is automatically invalid. The clause does not "shrink" to the legal maximum; it simply does not exist legally.
What happens during probation?
During a valid probation period, either party can terminate the contract with immediate effect and without giving a reason. Even so, termination may not be discriminatory or in violation of other fundamental rights, and you still build up certain protections (for example, against discrimination) from day one.
When a second probation is not allowed
If you move into a new contract with the same employer (or a successor employer) for essentially the same role, you usually cannot be subjected to a second probation period unless your job duties change substantially and require clearly different skills.
Probation red flags
- Probation in a contract of 6 months or less.
- A 2‑month probation in a 1‑year fixed-term contract.
- Probation clause only discussed verbally, not written.
- A second probation when you are doing the same work for the same employer.
2. Non-Compete Clauses: Post-Employment Restrictions
Concurrentiebeding (non-compete clause): A clause that restricts where and for whom you can work after your employment ends, usually by limiting your ability to work for competitors or start a competing business for a certain period and in a certain region.
Non-compete clauses are some of the most controversial provisions in Dutch employment contracts. They can severely limit your future career options, especially if you are an expat specialist in a niche sector. Dutch law has already tightened the rules for temporary contracts, and additional reforms are scheduled from 2025.
Current legal framework
Under Article 7:653 of the Dutch Civil Code, a non-compete clause is only valid if:
- It is agreed in writing (verbal agreements do not count).
- You are at least 18 years old when you sign.
- For fixed-term contracts, the employer provides a written justification explaining why a non-compete is necessary due to serious business interests.
As a rule of thumb, non-compete clauses are mainly intended for permanent contracts. In fixed-term contracts, they are only allowed in exceptional cases where the employer can prove a heavy business interest in writing.
What a non-compete clause typically covers
- Type of work: Which roles or activities you are restricted from performing.
- Which employers: Specific competitors or a defined sector.
- Geographical scope: Region, country, or global — overly broad scopes are more likely to be limited by courts.
- Duration: From 2025, expected maximum of 1 year after employment ends.
- Penalties: Daily or weekly fines if you breach the clause.
Upcoming changes from 2025
A bill to modernize non-compete clauses is scheduled to take effect on 1 January 2025 and will introduce important employee protections:
- Maximum duration: Non-compete clauses may not exceed 1 year after the end of employment.
- Mandatory geographical scope: The clause must specify a concrete area; vague worldwide bans will no longer be accepted.
- Written justification: Employers must always describe their substantial business interest, not only in fixed-term but also in permanent contracts.
- Mandatory compensation: If the employer invokes the non-compete, they must pay at least 50% of your last monthly salary for each month the restriction is enforced.
- Timely notification: The employer must inform you in writing and on time if they intend to enforce the clause; late notification or late payment can make enforcement invalid.
Existing non-compete clauses will generally remain valid, but employers who enforce them after the new law takes effect will still have to pay compensation.
What is negotiable?
The best time to address a non-compete clause is before you sign. In many cases you can negotiate:
- Removing the non-compete entirely if your role does not justify it.
- Shortening the duration to 6–12 months.
- Limiting scope to clearly defined competitors or a narrow region.
- Clarifying that it does not apply if your contract is terminated by the employer without serious cause.
- Agreeing on compensation now, even before the new law takes effect.
3. Notice Period: Planning Your Exit (or Dismissal)
Opzegtermijn (notice period): The amount of time between giving notice and the official end date of the employment contract. Different rules apply for employees and employers.
The notice period affects how quickly you can move to a new job and how much financial buffer you have if your employer ends the contract. It is governed both by statutory rules and by your specific contract.
Employee notice period
If you resign, the statutory notice period is generally 1 month, unless your contract or CAO says otherwise.
- Your notice period may be extended in your contract, but it may not exceed 6 months.
- If your notice period is longer than 1 month, your employer's notice period must be at least twice as long. For example, if you must give 2 months' notice, your employer must give at least 4 months.
Employer notice period
When your employer terminates the contract (outside probation), statutory notice depends on your length of service:
- Less than 5 years: 1 month.
- 5–10 years: 2 months.
- 10–15 years: 3 months.
- 15+ years: 4 months.
Collective labour agreements can sometimes provide for different notice periods, but your notice period cannot be disproportionately long compared to the employer's.
When does the notice period start?
Unless your contract says otherwise, notice usually takes effect from the end of the calendar month in which notice is given. If you give notice on March 10 with a 1‑month notice period, your employment normally ends on April 30.
Fixed-term contracts and the notification duty
Fixed-term contracts typically end automatically on the agreed end date. However, for contracts of 6 months or longer, your employer has a statutory notification duty (aanzegplicht): they must inform you in writing at least 1 month before the end date whether the contract will be renewed and on which terms.
If your employer fails to notify you in time, they can owe a penalty of up to one month's salary. This is separate from any notice period.
Consequences of not observing the correct notice period
If you leave earlier than your contractual notice period, your employer may claim compensation equal to the salary for the part of the notice period not worked. If your employer dismisses you too early, you can claim compensation equal to what you would have earned during the correct notice period.
