75 years of the Works Councils Act: what is an important decision?

By Koen Vermeulen

The Dutch Works Councils Act (WOR) has existed for 75 years. That was a reason for Or/net to ask members of works councils how the law could be improved.

A major wish among works council members is greater clarity about when there is an “important” intended decision. This is crucial for the works council: if the employer’s proposal meets the requirement of importance, the works council has a right to advice; if not, it does not. This blog explains this concept for the works council.

Right to advice

Or/net’s research shows that works councils consider Article 25 WOR the most important article. In several places, it states that the works council only has a right to advice if the intended decision is “important”. For example, in the case of a “significant reduction” in the business’s activities. It is already clear from this that not every reorganisation is subject to advice. The same applies to a “significant change in the organisation” or a “significant investment” or the raising of “significant credit”: only then does the right to advice arise. The works council’s wish for more clarity on when the requirement of “important” is met is understandable.

Important: not only in cases of major quantitative impact

Case law of the Enterprise Chamber already provides some guidance on this. The decision must be extraordinary and not part of the everyday management of the business, and it must be capable of having substantial consequences for the enterprise. This concerns so-called social, procedural and economic/organisational factors surrounding the intended decision. Social factors relate to the impact on employees: what are the consequences for employment and work duties, and how many employees are affected by the decision?

Even the dismissal of one employee can still fall within a “significant reduction” or organisational change if that person holds a key position or manages a large team. Procedural factors look at how often such decisions are taken, as well as the duration of the decision. In terms of economic/organisational factors, it matters whether the matter concerns a core activity of the business and how turnover is affected by the decision.

Guidance for the works council

What is therefore assessed is the scale and nature of the business’s activities and the impact of the decision on the business. In that sense, it is an assessment of all circumstances of the конкретe case. What may be considered an important, unusual decision for one business does not have to be an important decision for another. As a guideline when considering whether an intended decision is or is not important, the direct and indirect consequences for the persons employed in the business may be used as a benchmark.

Assessment by the works council

What questions can the works council ask itself and the employer, for example, in the case of a proposed reorganisation for which no advisory request has yet been received?

  • how many employees are involved in total, and how many will be dismissed?
  • what are the consequences for employment?
  • is this a one-off reorganisation, or are further rounds of redundancies expected?
  • what is the proportion of the activities to be reduced or changed compared with the total activities?
  • does the reorganisation affect a core activity of the business?
  • is the change part of a broader group strategy?
  • what is the impact of the reduction or change on the overall business operations?
  • to what extent will future growth and/or turnover be affected?

When personnel consequences arise, the right to advice often follows

When determining whether a decision is “important” and therefore subject to the right to advice, quantity is often the key factor: what percentage of turnover is affected, or how many roles will disappear as a result of the decision? But even if those numbers are limited, a decision can still be important if it affects a large part of the organisation. If the works council believes that a right to advice exists and the employer has wrongly failed to grant it because the requirement of “importance” was allegedly not met, it is up to the employer to make it plausible why that requirement has not been satisfied. If the employer cannot do so, the works council does in fact have a right to advice.

Case law shows that in the event of an organisational change with personnel consequences, an intended (reorganisation) decision will quickly be regarded as “important”. The works council should be alert to this. If you have any questions about this, the employment and employee participation lawyers of GMW lawyers are ready to assist the works council.

Employer, may I move to a competitor?

Many employers include a non-compete and/or non-solicitation clause in their employment contracts. If an employee wants to work for a client or a competitor of the employer, and the employer does not allow this, the employee may feel compelled to take the matter to court. That was also the case in a ruling by the Zeeland-West Brabant Subdistrict Court in May 2025.
