What compensation are you entitled to upon dismissal?

Dismissal in reorganisation - what do you need to know?

Dismissal during reorganisation follows strict rules through the principle of separation of staff. Your employer is not allowed to 'just pick and choose' who to kick out

The separation principle ensures fair distribution across age groups based on length of service with your employer

You have a total of 2 weeks to file a defence with the UWV. Make sure you meet this deadline.

Errors in procedure occur very regularly. Check the reflection carefully. When in doubt: contact us for free legal advice.

What is dismissal in reorganisation?

Dismissal in reorganisation means that your employer is making structural changes in the organisation where jobs disappear or change.

Causes

A reorganisation may be caused by the following:

  • Your organisation is facing financial difficulties, which means they need to cut back on labour
  • New technology changes (such as AI) make functions obsolete
  • A number of large customers have left structurally, resulting in less work 
  • Your company has moved to another location, making it impossible for some employees to work with you in the company
  • There has been a merger over acquisition, creating duplicate functions

The most important thing to remember: your employer cannot just decide who gets fired. There are strict rules that determine who gets fired first.

When there is formal reorganisation

A reorganisation is more than just cutting a few jobs. It involves a permanent change in the organisation. Before it can be formally called a reorganisation, your employer must be able to demonstrate that:

  1. The change is necessary for the survival of the business
  2. There is structurally less work
  3. Functions disappear for good
  4. There is no possibility of placing you in another department in the company

Strict rules

Even if employers can formally speak of a reorganisation, they have to follow strict procedures around firing employees. This goes wrong in many cases, as a recent example from our legal practice showed.

We were approached by a customer service employee on a permanent contract. Due to automation, half the employees could leave. Here, the employer made the choice to dismiss the employees who performed the least. To do this, he took all performance reviews and included this in his consideration. 

This is not allowed, because a reorganisation must be based on the principle of separation by virtue of age.

The separation principle explained

The apportionment principle is the legal method that determines which employees are laid off in a reorganisation. This principle ensures that the age structure of your team remains roughly the same after the reorganisation as before.

It was devised by the Dutch government in 2006 and formally enshrined in Article 11 of the redundancy regulations.

Why does the separation principle exist?

The apportionment principle prevents employers from dismissing employees arbitrarily or very specifically. Think, for example, of firing all older employees. Or just the expensive employees, who receive more salary. The system was devised to:

  • Preventing discrimination
  • Ensure objectivity in who is dismissed
  • Maintain an age distribution that existed before the reorganisation
  • Rule out arbitrariness

The basics: interchangeable functions

Before applying the multiplier principle, it must first be determined which jobs interchangeable are. Functions are interchangeable if they are similar in terms of:

  • Work content and tasks
  • Remuneration level (maximum 1 scale difference)
  • Knowledge and skills required
  • Responsibilities

Note: It is about the function, not the person. Even though your background might allow you to do a different job, that does not make that job interchangeable.

Lawyer pointing out that the lay-off principle is an important tool to prevent arbitrariness

The eight steps of the separation principle

Applying the separation principle is done according to a set roadmap. I walk you through them:

Step 1: Identify affected sites

Does your company have several branches? Then the separation principle applies for each branch. A branch is independent if it:

  • A business of its own has
  • Recognisable in society as a separate entity

Step 2: Group interchangeable functions

All functions that are interchangeable form one group. For example: all administrative staff level 3.

Step 3: Determine the reference date

The reference date is the day your employer submits the dismissal request to the UWV. It is on this date that we look at who is employed.

Step 4: First out: flexible shell

Before true mirroring begins, these groups must leave:

  1. Temporary workers and temporary workers
  2. State pension beneficiaries
  3. On-call workers (zero-hours contracts)
  4. Temporary contracts expiring within 26 weeks

Step 5: Divide into age groups

The remaining workers will be divided into five age groups:

  • 15 to 25 years
  • 25 to 35 years
  • 35 to 45 years
  • 45 to 55 years
  • 55 years to state pension age

Step 7: Seniority determines order

Within each age group: he who came last goes first. So your service time is crucial.

Step 8: Checking exceptions

There are some exceptions to the attrition principle:

  • Employees with a unique, indispensable function
  • Situations where application leads to a unreasonable result leads
  • Divergent rules in the CLA
Lawyer indicates that principle of attrition is not straightforward as there may be exceptions

Your rights in the event of reorganisation dismissal

Have you calculated above whether you can be dismissed on the basis of the principle of separation? If so, you have a number of important rights. We will go through them with you step by step.

1. Right to information

Your employer must give you timely and complete inform on:

  • The reason for the reorganisation
  • Exactly how many jobs will disappear
  • How the selection takes place
  • Planning the reorganisation

2. Right to reinstatement

Before you can be dismissed, your employer must seriously investigate whether you can be redeployed elsewhere in the company. This also applies to:

  • Positions in other branches (at large companies)
  • Functions you are suited to with short training
  • Lower-level positions (with retention of salary)

3. Right to notice

You are entitled to a statutory notice period that depends on your years of service:

  • 0-5 years employment: 1 month
  • 5-10 years employment: 2 months
  • 10-15 years employment: 3 months
  • 15+ years employment: 4 months

4. Right to transitional compensation

Upon dismissal, you are entitled to a transition allowance. This amounts to:

  • 1/3 monthly salary per year worked
  • Plus 1/12 monthly salary per month in an incomplete year

5. Entitlement to unemployment benefits

When dismissed due to reorganisation, you are usually entitled to a WW benefit. Your employer may not force you to "voluntarily" resign which will cause you to lose your unemployment benefits.

The UWV procedure when your employer reorganises

To dismiss you as an employee during a reorganisation, your employer must get permission from the UWV. This is how it works:

Phase 1: the application (weeks 1-2)

Your employer submits a resignation request to the UWV with:

  • A complete reorganisation plan, including substantiation
  • Staff overview with all positions, including FTE, time in service and age
  • Redundancy list calculating in which age groups redundancies will occur
  • Evidence of need (financial figures, business projections)

Important: You are entitled to a copy of this application. Please read it carefully!

Phase 2: your defence (weeks 3-4)

You have 2 weeks time to submit a written defence. This is your chance to demonstrate that:

  • The separation principle should have been applied incorrectly or differently
  • Placement opportunities do exist
  • The reorganisation is not necessary
  • You are an exception (e.g. indispensable to the organisation)

Phase 3: UWV assessment (weeks 5-8)

The UWV assesses whether:

  1. The reorganisation reasonable is
  2. The run-off principle correct has been applied
  3. Relocation sufficiently examined
  4. The procedure carefully has been followed

Stage 4: the decision

The UWV can make three decisions:

  • Granting permission: your employer may fire you
  • Refusing permission: you keep your job
  • Ask additional questions: need more information

If the UWV gives permission, your employer must be within 4 weeks terminate the employment contract. If he fails to do so, the consent will lapse.

Objecting to reorganisation dismissal

Objecting to your dismissal can be done at different times and in different ways. Here are your options:

1. During the UWV procedure

This is the key moment to take action. Focus your defences on:

Errors in the separation principle:

  • Are all interchangeable positions included?
  • Are the age groups correct?
  • Has seniority been calculated correctly?
  • Were flex workers fired first?

Reassignment opportunities:

  • Have all vacancies been viewed?
  • Has training been offered?
  • Have lower positions been considered?
  • Has it been looked at in other branches?

The need for reorganisation:

  • Are the financial figures correct?
  • Have alternatives been explored?
  • Is the forecast realistic?

2. After the UWV's decision

Does the UWV give permission? Then you can:

  • Objection make it to the UWV (within 6 weeks)
  • Profession file with the court
  • Negotiate about a settlement agreement

3. Practical tips for your defence

Collect evidence:

  • Store vacancies at your workplace
  • Document your range of tasks
  • Save emails about the reorganisation
  • Record dates of calls

Seek support:

  • Engage a lawyer (completely free and without obligation with us)
  • Contact the works council or union
  • Form a group with colleagues
Lawyer indicating that reorganisations can also often involve a social plan

Severance pay and social plan

When you are made redundant due to reorganisation, you are entitled to financial compensation. Let's see what you can expect:

The statutory transitional allowance

Every dismissed employee is entitled to a transition allowance. The amount depends on your years of service and salary. For an exact calculation of your transitional compensation, use the severance pay calculator.

The social plan: often more than the law

In larger reorganisations (20+ redundancies), there is usually a social plan. This is negotiated with unions or the works council and often includes:

Additional fees:

  • Supplement to the transitional allowance
  • Compensation per year of service
  • Jubilee bonus
  • Unused holidays

Guidance:

  • Outplacement process
  • Job training
  • Career advice
  • Study budget

Practical arrangements:

  • Exemption from work during job applications
  • References and testimonials
  • Taking over lease car
  • Retaining laptop/phone
Negotiating your severance package makes sense in many cases. Even in a reorganisation.

Negotiating your severance package

Even with a social plan, there is often room for negotiation. In a previous case in which we negotiated for an employee, employee indicated after the negotiation:

"I am now fully exempt from work and have finalised everything with my employer through a VSO. Relieved and happy."

Before you start negotiating:

  1. Know your value - what are your unique contributions?
  2. Ask for more than the minimum - there is often room for schemes, including financial ones
  3. Also consider non-financial matters - such as references, LinkedIn recommendation
  4. Get free assistance from us - our lawyers know the usual amounts

Conclusion

Dismissal during reorganisation is in many cases a long process of uncertainty for employees. For a long time, you often do not know where you stand or what you are entitled to.

It is good to realise that the attribution principle protects you from arbitrary dismissal and the law gives you clear rights in the dismissal process.

Whether you are just hearing that a reorganisation is coming or are already in the middle of the process: make sure you are aware of what you are entitled to. 

The key lesson from our experience of many reorganisations? Employers make mistakes. Especially when applying the separation principle, things regularly go wrong. A critical look at the calculations, a well-founded defence at the UWV, or smart negotiations on your severance scheme can make thousands of euros difference.

Are you facing this situation? Don't wait, but take action. Gather documents, ask questions, and seek professional help. We offer free redundancy support. Take action today contact.

Experience by Nina Consent sharing story
Review via trustpilot

"Definitely recommended. Started by filling in the calculation tool in which it quickly became clear what I am entitled to. Then low-threshold contact and result is there. Thanks!!!"

What was the situation?

Nina had been working as a marketing specialist for three years when her employer asked her to talk about a so-called "amicable settlement." This was because the company was facing financial problems and wanted to save costs. Nina was presented with a vso, which included mutual agreement dismissal as the reason for dismissal. This did not include a severance payment and the reason for dismissal was unclearly worded. 

What did we do?

After Nina shared her vso with us, we contacted her to further clarify the situation and go through all parts of the vso together. At ontslagrechtjuristen.nl, we discovered that her employer had made a proposal mainly for its own benefit, with compensation that was far too low. Nina indicated that we could contact her employer to discuss the settlement agreement. After several discussions with her employer, she received fair compensation, was entitled to unemployment benefits and could count on a work release.
