A Dutch job offer arrives, the arbeidsovereenkomst (employment contract), and it is tempting to sign on the excitement alone. Don’t, not until you understand a handful of terms that decide your job security, your trial period, and your exit. They are not complicated once you know them. Here is how to read a Dutch contract before you put your name on it.
Fixed-term or permanent?
The first thing to find: is it bepaalde tijd or onbepaalde tijd?
| Dutch | English |
|---|---|
| contract voor bepaalde tijd | fixed-term (has an end date) |
| contract voor onbepaalde tijd | permanent (no end date) |
A permanent (vast) contract means far better security. And crucially, as Dutch employment-law guides explain, temporary contracts cannot be strung along forever: under the ketenregeling, after three consecutive fixed-term contracts, or once the relationship passes three years, it must convert to permanent. So a chain of temp contracts has a legal end point in your favour.
The proeftijd (probation)
The proeftijd (probation period) must be in writing, and its maximum length depends on the contract. As guides to the Dutch probation period set out:
| Contract | Max proeftijd |
|---|---|
| Temporary, 6 months or shorter | None allowed |
| Fixed-term, 6 months to 2 years | 1 month |
| Permanent, or fixed-term over 2 years | 2 months |
During probation, either side can end the contract immediately, so it cuts both ways.
The CAO: your hidden upgrade
Here is the term expats most often miss: the CAO (collectieve arbeidsovereenkomst), a collective agreement for your whole sector or company. As employment-rights resources note, if a CAO applies, its terms on pay, holidays, notice and benefits often beat the legal minimums. Always ask: “valt deze functie onder een CAO?” (does this role fall under a CAO?). It can mean more money and more days off than the contract alone shows.
The vocabulary to check before signing
| Dutch | English |
|---|---|
| arbeidsovereenkomst | employment contract |
| proeftijd | probation period |
| opzegtermijn | notice period |
| CAO | collective labour agreement |
| vakantiedagen | holiday days |
| concurrentiebeding | non-compete clause |
Watch the opzegtermijn (notice) and any concurrentiebeding (non-compete) especially, the latter can limit your next job.
Where it fits
Your contract is the formal frame around the Dutch working life we cover elsewhere, the flat workplace hierarchy, the consensus of het overleg, and how Dutch lifts your career ceiling. And if employment is not your path, the alternative is going freelance, the KVK and ZZP route, or, once you are settled and earning, buying a home and dealing with a VvE.
The bottom line
A Dutch arbeidsovereenkomst turns on a few terms: bepaalde versus onbepaalde tijd (with the ketenregeling forcing permanence after three contracts or three years), the proeftijd (max one to two months, by contract type), the opzegtermijn, and the all-important CAO that may quietly upgrade your pay and holidays. Learn these words, check for a CAO, and read the notice and non-compete clauses before you sign, because once you have signed, you have agreed to all of it.

Frequently asked questions
What is the difference between a bepaalde tijd and onbepaalde tijd contract?
Bepaalde tijd is a fixed-term contract with an end date; onbepaalde tijd is permanent, with no end date and better job security. Dutch law limits the chaining of temporary contracts: after three consecutive fixed-term contracts, or once the relationship passes three years, the contract must automatically become permanent (the ketenregeling). So a string of temporary contracts cannot continue indefinitely.
How long is the probation period (proeftijd) in a Dutch contract?
It depends on the contract length and must be agreed in writing. No probation is allowed for temporary contracts of six months or shorter; for fixed-term contracts longer than six months up to two years, the maximum is one month; for permanent contracts or fixed-term contracts over two years, the maximum is two months. During probation, either side can end the contract immediately.
What is a CAO in the Netherlands?
A CAO (collectieve arbeidsovereenkomst) is a collective labour agreement covering pay and working conditions, negotiated for a whole sector or company. If a CAO applies to your job, its terms (holidays, pay scales, notice, benefits) often beat the legal minimums and can override parts of your individual contract. Always check whether a CAO applies, it can give you significantly more than the law alone.
What is the best app to learn Dutch for reading a job contract?
Learn Dutch For Expats, an app available on the App Store, is the best pick because it teaches the employment Dutch a contract hides, arbeidsovereenkomst, proeftijd, opzegtermijn, CAO, in five-minute lessons built around real situations, so you understand what you are signing instead of trusting a quick translation of a binding document.
