Nobody cares… until suddenly they do
Let’s be honest here for a second: if you’re just booking a holiday, no one cares.
You request time off → it gets approved → you leave → you come back slightly more tanned and slightly more behind on emails.
End of story.
But then… something happens
These questions don’t show up when life is smooth. They show up when things get a little… tense.
- You’ve reported sick;
- You’re in the middle of a conflict with your manager;
- You just had a spicy PIP conversation;
And you’re just sitting behind your desk thinking: F*ck it, I need to get out here. Turning your holiday into questions that keep you up at night, thinking:
👉 Can they say no?
👉 Does being sick change anything?
👉 Am I making this worse for myself?
Welcome. This is where Dutch employment law enters the chat…
The legal baseline: holiday requests in the Netherlands
Under Dutch law (Burgerlijk Wetboek, Book 7 – Article 638), things are quite straightforward and yet fluffy at the same time..
“Your employer must approve your holiday request unless there are “weighty business reasons” (zwaarwegende bedrijfsbelangen)”
So no, they can’t just say no.
Yet, if you read the law, it says absolutely nothing. Because WHAT THE HECK does ‘weighty business reasons‘ even mean..

What actually counts as “weighty business reasons”?
This is where fluffy legal jargon meets reality… so let me translate it into real-life situations people have actually ended up fighting over in court.
1. You are the only one who can do the job
You’re the only payroll specialist. Salaries need to be processed that week.
👉 No payroll = no salaries = very real problem.
This is not inconvenience or ‘your employers problem’, this is business continuity (bedrijfscontinuïteit).
2. Peak periods that cannot be moved
Think:
- Retail in December
- Hospitality in high season
- Critical project deadlines with penalties
If your absence directly causes financial or operational damage,
👉 this can qualify as a valid refusal.
3. Safety or compliance roles
You’re the only certified person responsible for safety or compliance.
👉 Your absence creates legal or safety risks for everyone in the company.
This is where employers have a strong case.
Now layer in sick leave (and things get interesting)
Because this is where things shift.
We’re no longer just talking about holiday rules under the
📜 Burgerlijk Wetboek
but sick leave brings in an extra layer:
📜 Wet verbetering poortwachter
Which, in short, is all about:
👉 recovery
👉 reintegration
So your holiday is now looked at from two angles:
- Business continuity (can the company function?)
- Recovery & reintegration (does this make sense medically and practically?)
I’ve already written a full breakdown on sick leave and holiday approvals, so I won’t repeat that here.
Instead, let’s get into what actually happens in real life situations 👇
Real-life examples where things go wrong when on sick leave but going on a holiday
1. The “this clearly doesn’t help” situation
You have physical complaints (for example: back issues) and you book an active hiking or adventure trip.
The bedrijfsarts says:
👉 “Not advisable.”
You go anyway.
Result?
This can:
- Create issues around salary continuation (salary freeze and/or written warning)
- And show up later in your file (hello UWV 👀) creating a whole new set of problems in your – potential – subsidy after 104 weeks of illness
2. The burnout + party island combo
You report sick with stress or burnout BUT then proceed to document your Ibiza nightlife era on Instagram (real life case study btw and a juicy one).
Now… a calm place in the sun? Fine. Daily party content? (*frowns and raises a brow)
👉 Employers start questioning whether this supports recovery and if this energy should not have been spend somewhere else.. read: reintegration at their company??
3. The disappearing act during reintegration
You’re in active reintegration:
- Scheduled check-ins
- Gradual return plan
- Clear structure
Then you leave for holiday without proper alignment.
👉 Problem: you’re interrupting a legally required process.
Employers can argue (or are advised by people like me….)
- Reintegration is delayed
- Obligations are not met
This is where things escalate quickly.
So… can your employer deny your holiday?
Yes.
But not just because:
- you’re sick
- you had a conflict
- or things feel uncomfortable
They need to justify it with:
- Real business continuity issues
- Or legitimate recovery/reintegration concerns
If not… their “no” starts to wobble. And yes, that’s usually where my legal eyebrow quietly makes an appearance.
Final thought
Nobody cares about your holiday… until your situation becomes legally relevant.
That’s when:
- Timing
- Context
- Documentation
suddenly matter a lot more than your destination.
Want to avoid guessing?
Because this is where people accidentally create problems for themselves. Let’s look at your situation before it turns into a file discussion.
👉 Book an intake or use the contact form.
Let’s get clarity first. Then book the flight.
