Why a penalty clause can be the salvation for your business
Suppose your key sales manager leaves for the competition and takes your entire customer base with him. A nightmare scenario. What can you do? A penalty clause in the employment contract can help. Think of the penalty clause as a kind of safety net, an insurance policy against this kind of undesirable behaviour.
It is a legal tool that is increasingly used, especially in sectors where protecting confidential information is crucial.
Penalty clauses in different sectors
So where do we often see penalty clauses? Think finance, ICT and consulting firms. In these industries, protecting trade secrets and customer data is especially important. In the Netherlands, the use of penalty clauses in these sectors is relatively high. The Algemene Werkgeversvereniging Nederland (AWVN) conducted research into this and found that in 2019, around 12% of Dutch employment contracts contained an explicit penalty clause.
How does a penalty clause work in practice?
A penalty clause can protect your business in various situations. Think, for example, of violating confidentiality obligations or ignoring a non-competition clause. Back to our sales manager. If he takes his customer base to a competitor, the penalty clause allows you to impose a financial penalty.
Besides the actual financial consequences, a penalty clause also has an important psychological effect. It can have a preventive effect by making employees aware of their responsibilities. However, it is not a panacea and there are many misunderstandings about what a penalty clause can and cannot do.
When is a penalty clause effective?
For a penalty clause to be truly effective, it must be drafted clearly and unambiguously. It must be clear to everyone what behaviour leads to a fine and how high the fine is. The amount of the fine should also be proportionate to the seriousness of the offence. An excessive fine can be mitigated by the court.
A penalty clause is not a licence to intimidate employees. It is a tool to protect your business interests and clarify mutual expectations.
Navigating the legal boundaries of penalty clauses
Imagine: you have traffic rules, not to bully, but to make sure everyone gets home safely. This is also how rules around penalty clauses in employment law work. They protect both you as an employer, and your employees. Section 7:650 of the Civil Code describes the main rules, but that legal language is sometimes quite complicated. Let’s untangle them together and translate them into practical tools.
Reasonableness and proportionality: the heart of the matter
A €500 fine for being late? That doesn’t feel fair, does it? A fine should be proportional to the offence. Think of a parking fine: a small amount for a minor offence, a larger amount for wrong parking that inconveniences others.
Your employee’s financial situation also plays a role. A high fine can be a huge chunk of salary for a low-paid employee, while the same fine has less impact for a top earner. This is where some employers go wrong with their penalty clauses.
The legislation is quite detailed. So it is important to handle it carefully. For example, the maximum penalty per week should not exceed the wages of half a working day (Article 7:650(2) of the Civil Code).
The role of the Labour Inspectorate
The Labour Inspectorate checks that everyone follows the rules. Violation can lead to sanctions. So a good penalty clause is not a matter of copy-paste, but tailor-made. It should suit your specific situation and the nature of the work.
Drafting the perfect penalty clause that passes every test
Drafting a solid penalty clause is not always easy. It is important that all parts are well put together, otherwise it will not work as intended. In this section, we will discuss step by step how to draft a penalty clause in an employment contract that is both legally correct and works well in practice. We start with the basics: which elements are indispensable and what makes a clause really strong?
Clarity above all else: concrete examples
Concrete examples of good and bad wording make it immediately clear what works and what doesn’t. Suppose you want to impose a fine for late submission of reports. A vague sentence like “timely reporting is required” is not enough. It is much better to specify, “Reports must be submitted by 5pm every Friday.” That way you avoid discussions.
We also show how to classify different types of offences and link appropriate fines to them. For example, consider a low fine for a one-off mistake, versus a higher fine for repeatedly ignoring agreements. Proportionality is very important here.

The art of legal writing: clear and understandable
Legal language can be complicated, but your penalty clause does not have to become unreadable. Write in clear language that is understandable to both the employer and the employee. Avoid jargon and explain difficult terms. Clear terms avoid discussions about what is and what is not allowed.
Implementation in practice: from old to new
How do you add a penalty clause to existing contracts and how do you introduce it to new employees? We discuss some practical strategies. A penalty clause need not be a deterrent, but can actually contribute to a professional and clear working relationship. Explain the purpose of the penalty clause and stress that it is about fulfilling important agreements. In existing contracts, consulting with the employee and putting the change in writing is very important.
When drafting a penalty clause, consider the following points:
- Specificity: Describe exactly what behaviour leads to a penalty.
- Proportionality: Make sure the amount of the fine fits the severity of the offence.
- Clarity: Use clear language and avoid legal jargon.
- Communication: Discuss the penalty clause with your employees and explain the purpose.
By following these steps, you will create a penalty clause that is not only legally sound, but also contributes to a pleasant working environment.
How judges assess your penalty clause and what it means
Imagine this: you have drafted a penalty clause, all according to the rules, you think. But a judge looks at it with a different perspective. It is important to understand how judges think about “reasonableness” and “fairness“. Otherwise, your carefully drafted penalty clause will soon be worth nothing.
The judge as referee: is it fair?
A judge can moderate a penalty clause, or even declare it invalid altogether. Like a referee on the football field, the judge pays attention to fair play. A €10,000 fine for a small mistake? Red card! That’s not proportionate and the judge will whistle you back.
Three main questions asked by the judge
Proportionality, transparency and knowability: these are the three magic words. Is the fine proportionate to the fault? Is the text of the penalty clause clear? And did the employee really know what the consequences could be? If the answer to any of these questions is “no”, you have a problem.
Trends in the courtroom: intimidation doesn’t work
Judges are increasingly poking through when a penalty clause is actually designed to intimidate employees. A penalty clause may well be strict, but it must serve a reasonable purpose. Protecting trade secrets? Fine. Sow fear? Not OK.
From case study to lesson: where do things often go wrong?
An example: an employee accidentally leaks confidential information. Immediately impose a sky-high fine? The judge looks at the context: intentional or an unfortunate mistake? The employee’s financial situation and working relationship also play a role.
External factors: the complete puzzle
The judge weighs all factors. How long has the employee worked at the company? What is his job title? Previous offences? It is like a jigsaw puzzle: all the pieces add up to the final verdict. So a good penalty clause is tailor-made.
Lessons from practice: successes and spectacular failures
The theory around penalty clauses is of course important, but let’s face it: practice is where things get really exciting. Imagine an IT consultant who wants to move to a competitor with sensitive information. A good penalty clause can deter him or her considerably. Or that financial consultant who thought he could just take his client database with him. A hefty fine, approved by the court, provided a painful lesson.
Failures: where did it go wrong?
Of course, things sometimes go wrong with penalty clauses. Take that software company that wanted to impose a €50,000 fine for a relatively minor offence. The judge swept it off the table. Or that consultancy with a penalty clause as vague as butter, which meant that no violation could really be proven. Learning moments!
Lesson for you: learning from mistakes
These examples show how crucial a well-worded penalty clause is. Clarity is paramount. What worked, what didn’t, and what can we learn from it? They are valuable insights that will help you draft a watertight penalty clause.
Different sectors, different challenges
Each sector has its own dynamics. For example, the healthcare sector is very different from the tech world. Therefore, it is important to tailor your penalty clause to the specific circumstances of your industry and company. Consider the nature of the work, the sensitivity of information and the position of the employee.
Analysis of successful penalty clauses
Back to that IT consultant for a moment. Why was that penalty clause so effective? It was clear, specific, and aimed at protecting trade secrets. The fine was proportionate and the consultant was aware of the consequences.
Analysis of failed penalty clauses
And that software company with the €50,000 fine? That one was totally out of proportion. An important lesson: the fine should be proportionate to the seriousness of the offence.
By learning from the mistakes of others, you increase the chances that your penalty clause in the employment contract does have the desired effect.
From offence to collection: your practical roadmap
Suppose an employee breaks the rules and you want to use the penalty clause in the employment contract. How do you go about this without getting into legal trouble? Think of this section as your personal roadmap.
Recognising and recording violations: from suspicion to evidence
Evidence first. A vague suspicion is not enough. Collect concrete evidence, such as emails, witness statements or log files. Document everything carefully, just like a detective does in an investigation. This will form the foundation of your case.
Think of a solid foundation on which to build further. Without solid evidence, your case stands shaky.
The notice of default: a formal warning
You then put the employee in default in writing. Think of it as a yellow card in a football match: an official warning. Clearly state the offence, the amount of the fine and the deadline by which it must be paid. This letter must meet specific requirements, so consult with a lawyer to make sure everything is correct.
A lawyer can help you use the right wording and make sure you don’t overlook important details.
Communication and deadlines: the right tone and timing
Keep communication professional and respectful. An angry e-mail will only weaken your position. Give the employee space to respond and stick to the legal deadlines. Just like baking a cake: adding the right ingredients at the right time is essential for the desired result.
Patience and a professional approach are crucial here.
Alternatives to debt collection: talking sometimes pays off
A conversation can sometimes be more effective than a lawsuit. Consider negotiating an amicable settlement. You may be able to reach a compromise, such as a lower fine or a payment plan. This will save time, money and energy for both parties.
Sometimes a good conversation is the quickest way to a solution.
Challenge and refusal: how do you respond?
What if the employee disputes or refuses to pay the fine? Stay calm and seek legal advice. Sometimes using a lawyer is unavoidable. Weigh the costs and benefits: when does persistence make sense and when not? A lawyer can advise you on this.
It is important to make an informed decision and not act in haste.
Administration: a watertight file
Keep all important documents carefully. Think of the employment contract, the notice of default, supporting documents and all correspondence. A well-organised file is your best defence. Think of it as a well-organised filing cabinet: everything neatly stored and easy to find. This will save you a lot of trouble should the case go to court.
A clear file ensures that you have the right information at hand quickly.
Common questions and dangerous misconceptions debunked
Picture this: a penalty clause – it sounds like a solid tool to enforce the rules. But it does come with a hefty instruction manual. Let’s straighten out some misunderstandings surrounding the penalty clause in an employment contract, so you won’t have any surprises.
Can you just deduct a fine from salary?
Think of red light running: you get a ticket first, before you have to pay. It works the same way with a penalty clause. You can’t just deduct money from someone’s salary. A notice of default is the first step. In it, you give the employee a chance to respond and still pay the fine. Only if this is not met, you can consider further steps.
Can a penalty clause be added to a contract retrospectively?
Imagine changing the rules halfway through a game. That’s not fair. Adding a penalty clause in an employment contract works the same way. You need the employee’s consent. No one can be forced to agree to new terms. Consultation is key here! A new agreement or addendum, signed by both parties, is the best approach.
What if an employee refuses to sign?
Forcing is not an option. Try to engage in conversation and understand the reasons behind the refusal. Explain why the penalty clause is there and its importance, also for the employee. Perhaps there are alternative solutions that do work for both parties. Consider another way of recording agreements.
Penalty clauses on home workers, flex workers and self-employed workers?
In principle, the rules around penalty clauses apply to all employees, including home workers and flex workers. With self-employed people, the situation is often different, unless they really function as employees. In that case, however, the penalty clause must suit their specific situation. The nature of the work and the agreements made play a role here. A lawyer can advise on this.
Social media and penalty clauses: what if trade secrets are leaked?
Leaking trade secrets via LinkedIn or Twitter? That can certainly be grounds for a fine. But clearly define what information is confidential and what is not-done online. A clear social media policy can help.
Can the employer keep the fine for himself?
It is not legally permissible for fines imposed on employees to directly or indirectly benefit the employer or the person imposing the fine on behalf of the employer. To avoid this, it is advisable to record that any fines will be transferred to a fund or treasury managed for the benefit of staff. This could be a staff association, events committee or other collective provision, for example. Donating to charity is also sometimes chosen as a destination. It is important here that the employer does not benefit financially from this construction, for instance by deducting the deposits from obligations to the fund. In that case, there could still be an advantage for the employer, which is not allowed.
The future of penalty clauses: what can we expect?
Laws and regulations are constantly changing, and so are the rules around penalty clauses in employment contracts. Keep abreast of developments, for instance through a lawyer, to keep your penalty clause up-to-date.
