5 key clauses in Dutch employment contracts

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

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

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

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 on 29 June 2026 a bill to modernize the non-compete clause went to the Raad van State.

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: Proposed reforms aim for a maximum of 1 year after employment ends.
• Penalties: Daily or weekly fines if you breach the clause.

Planned changes: the 2026 reform bill

On 29 June 2026 the minister sent the bill to modernize the non-compete clause to the Raad van State for advice. The government aims to present it to the Tweede Kamer at the end of 2026, so it is not law yet. As proposed:

• Maximum duration: the clause may apply for at most 1 year.
• Stated area: the clause must say which area it covers.
• Compensation: the employer must pay you compensation when invoking the clause.
• Relation clauses: a ban on working for or with clients and other relations of your former employer is covered too.

Until parliament passes the bill, the current rules above apply.

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 any new law fully takes effect.

3. Notice period: planning your exit (or dismissal)

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 (aanzegplicht)

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.

Notice for both sides, and when none applies: notice period in the Netherlands.
