The 6-Month Trap: Can You Use a Probation Period in a Short Dutch Contract?
Many international managers assume a one-month probation period is standard in any Dutch employment contract. This common mistake can lead to costly wrongful dismissal claims. Discover the reality of Dutch law for fixed-term contracts.

The Myth: "You can always include a one-month probation period in a Dutch employment contract. It's a standard safety measure."
This belief is a classic example of applying a 'one-size-fits-all' international HR policy to the specific legal landscape of the Netherlands. While probationary periods (proeftijd) are common, their application is strictly regulated, especially concerning fixed-term contracts.
The Scenario: A Costly Assumption
Meet David, the new Head of People for 'Global Foods BV,' a rapidly expanding food-tech company in Amsterdam. Tasked with staffing a crucial six-month project, he hires a talented data analyst, Sophie. Drawing from his experience in the UK, David issues a standard six-month employment contract that includes a one-month probationary period. Both parties sign, and Sophie starts work.
Three weeks later, due to an unexpected budget reallocation, the project is cancelled. David feels a pang of regret but is relieved they included the probation clause. He calls Sophie into his office and informs her that, while she has been great, her employment is being terminated within the probationary period, effective immediately. He thinks it's a clean break.
He's wrong. A week later, a letter arrives from Sophie's legal counsel. It states her dismissal was unlawful and demands payment for the remaining 5+ months of her contract. David is baffled. How could a mutually agreed-upon probation clause be invalid?
The Reality: The Law on Probationary Periods
Dutch law is very precise on this point to protect employees on short-term contracts. The rule, found in the Dutch Civil Code (Article 7:652), is crystal clear:
A probationary period clause is void (nietig) if it is included in a temporary employment contract with a term of six months or less.
This means the clause legally never existed. When David terminated Sophie's employment, he wasn't using a valid probation clause; he was unlawfully dismissing an employee. Because there was no legal basis for the termination, Global Foods BV was liable for her salary for the entire duration of the contract.
The AI Clarity Moment: A Smarter Question
How could David have avoided this expensive and stressful situation? Before issuing the contract, he could have turned to his AI legal copilot.
He could have asked LawYours.AI a simple question: "Can I include a one-month probation period in a 6-month fixed-term contract in the Netherlands?"
Within seconds, the AI would have delivered a clear, direct answer:
"No, under Dutch law (Art. 7:652 BW), you cannot include a probationary period in a fixed-term employment agreement with a duration of six months or less. Any such clause is considered legally void. For contracts longer than six months but shorter than two years, a one-month probationary period is permissible."
This simple query would have given David the actionable intelligence needed to draft a compliant contract, potentially offering a seven-month contract to include a valid probation period or accepting the risk of a six-month contract without one.
3 Simple Rules to Remember
To avoid the '6-Month Trap,' keep these clear rules in mind for Dutch employment contracts:
- Contract of 6 Months or Less: No probationary period is allowed. Period.
- Contract Longer Than 6 Months (but less than 2 years): A maximum of a one-month probationary period is allowed.
- Permanent Contract or Contract of 2 Years or Longer: A maximum of a two-month probationary period is allowed.
Always verify contract clauses against local laws. What is standard practice in one country can be a direct violation in another. Don't let a simple, preventable assumption become your next big legal headache.
