A 2-Month Probation in a 6-Month Dutch Contract? The Legal Myth That Will Cost You
Many international managers assume probation periods are flexible in the Netherlands. This is a costly mistake. Discover the strict Dutch rules and see how AI can provide instant clarity before you make a hiring error.

The Myth: "In the Netherlands, you can include a probation period ('proeftijd') in any employment contract, and its length is flexible as long as both parties sign it."
This belief is common among international managers hiring in the Netherlands for the first time. It’s also completely wrong and can lead to serious legal complications.
The Scenario: A Costly Assumption
Meet David, an Operations Manager for ‘Global Reach Logistics BV,’ a new Amsterdam branch of an American firm. Tasked with building his team, he hires Anouk for a crucial six-month logistics coordinator role to manage a pilot project.
Coming from a US hiring culture, David adds a 'standard' two-month probation period to her six-month contract. He figures this gives him enough time to evaluate her performance. Anouk, excited about the job, signs the contract without question.
Five weeks later, David decides Anouk isn’t the right fit. He calls her into his office and terminates her employment, referencing the probation period. He expects a simple, clean break.
Instead, he receives a letter from Anouk's legal counsel a few days later. The letter states that her dismissal was unlawful. Why? Because the two-month probation period in her six-month contract was legally void from the start. Anouk was, and remains, a fully protected employee.
The Reality: Dutch Law is Strict and Specific
In the Netherlands, probation periods are not flexible negotiation points; they are strictly regulated by law (Article 7:652 of the Dutch Civil Code). The maximum allowed duration is tied directly to the length of the employment contract.
Here are the hard rules:
- Contracts of 6 months or less: No probation period is allowed. Zero. None.
- Contracts longer than 6 months but shorter than 2 years: A maximum of one month is allowed.
- Permanent contracts or contracts for 2 years or longer: A maximum of two months is allowed.
If you include a probation period that violates these rules (like David’s two-month period for a six-month contract), the clause is automatically void (nietig). It’s as if it never existed. This means the employee has full dismissal protection from day one.
The AI Clarity Moment: Prevention in Seconds
This entire costly and stressful situation could have been avoided. Before sending the contract, David could have asked a legal AI copilot like LawYours.AI a simple question:
“What is the maximum probation period for a 6-month fixed-term contract in the Netherlands?”
In seconds, the AI would have provided a clear, source-linked answer:
“Under Dutch law (Article 7:652 BW), no probation period is permitted for employment contracts with a duration of six months or less. Including a probation period in such a contract would render the clause void, and the employee would be fully protected from the start of their employment.”
This simple, proactive check would have given David the clarity needed to draft a compliant contract, saving Global Reach Logistics BV from a significant legal and financial headache.
3 Simple Rules to Remember
- Check Contract Duration First. The length of the employment contract is the only thing that determines the maximum valid probation period.
- Six Months or Less = Zero Probation. This is a non-negotiable, bright-line rule. There is no room for exceptions.
- Always Get It in Writing. For contracts where a probation period is allowed, it must be agreed upon in writing by both parties to be valid.
