Employer not complying with the collective labour agreement: your options

If your employer is not complying with the collective labour agreement (collectieve arbeidsovereenkomst, CAO) that binds it, you can claim what the agreement gives you, with retroactive effect. A term in your employment contract that conflicts with an applicable collective agreement is void under article 12 of the Collective Agreements Act, and the collective agreement provision applies in its place. Claims for unpaid wages and allowances can normally be brought before the subdistrict court for five years back.

This article explains when an employer is actually bound, what happens to arrangements that undercut the collective agreement, what you can claim and within what period, what the trade unions and the collective agreement parties can do that you cannot, and where the Netherlands Labour Authority fits in. It is written for employees who suspect they are being underpaid and for employers who want to know what exposure they are running.

When is an employer bound by a collective labour agreement?

There are three routes, and they have different consequences. The first is membership: an employer that belongs to an employers’ organisation which concluded the agreement is bound by it, as is an employee who is a member of one of the trade unions involved. The second is a general binding declaration (algemeenverbindendverklaring), by which the Minister of Social Affairs and Employment extends the provisions of a sector agreement to every employer and employee in that sector, whether or not they are members of anything. The third is contractual: many employment contracts contain an incorporation clause (incorporatiebeding) declaring a named collective agreement applicable, which binds the employer even where neither of the first two routes does.

The starting point is therefore your own employment contract, which must state which collective agreement applies. That is not merely good practice: an employer is obliged to inform the employee in writing about the terms of the employment relationship, including the applicable collective agreement, under article 7:655 of the Civil Code. If the contract is silent, look at the sector, the activities the company actually carries out and the general binding declarations published in the Government Gazette; the scope provision (werkingssfeerbepaling) of the collective agreement, not the label the employer uses, decides whether the company falls within it.

One point regularly missed: an employer that is bound by a collective agreement must in principle also apply its terms to employees who are not union members, under article 14 of the Collective Agreements Act. That obligation is owed to the collective agreement parties. Whether the individual non-member employee can enforce it directly depends on whether the agreement has been declared generally binding or the employment contract contains an incorporation clause, which is precisely why that clause matters so much.

A clause that undercuts the collective agreement is void

Employers sometimes assume that a separate arrangement with the employee overrides the collective agreement. It does not. Under article 12 of the Collective Agreements Act, a term agreed between an employer and an employee that conflicts with a collective agreement binding on both of them is void, and article 13 provides that the collective agreement provision applies in its place. Nothing has to be renegotiated: the correct wage scale, allowance or notice period simply applies, and the employee can claim the difference.

The consequence for employers is that a signed contract is no defence. If the pay scale used is below the scale the collective agreement prescribes for the work actually performed, the shortfall is owed for the whole period, together with holiday allowance and any pension contributions calculated on it. In practice the largest claims arise not from deliberate underpayment but from job classification: an employee is placed in a lower function group than the duties justify, and the error is repeated every month for years.

Deviation is not always forbidden. Many collective agreements are minimum agreements (minimum-CAO), which allow terms that are more favourable to the employee, while a standard agreement (standaard-CAO) permits no deviation in either direction. Some provisions expressly allow deviation by written agreement or at company level. Read the agreement before assuming either that everything is fixed or that anything can be negotiated; our overview of Dutch employment law sets out how these rules fit together.

General binding declarations, and what happens when they expire

A general binding declaration is made by the Minister of Social Affairs and Employment for a fixed period and is published in the Government Gazette. It never covers the whole agreement: only the provisions listed in the decision become binding, and companies can apply for an exemption where they are bound by their own equivalent agreement. The declaration takes effect after publication and does not work retroactively, even where the collective agreement parties gave their own agreement retroactive effect for their members.

The end of a collective agreement is a separate question. For employers and employees bound through membership, the normative provisions that have become part of the individual employment contract continue to apply after the agreement expires until something else is agreed; this after-effect (nawerking) is why employees rarely lose acquired terms overnight. Provisions that applied only because they had been declared generally binding, by contrast, in principle stop applying when that declaration ends. In the gap before a new agreement is declared binding, the individual employment contract and the statutory minimum wage are what remain.

What you can claim, and how far back

An employee who has been paid less than the collective agreement requires can claim the difference as unpaid wages before the subdistrict court (kantonrechter), which handles employment claims regardless of the amount. Three additions usually accompany that claim. The statutory increase for late payment of wages under article 7:625 of the Civil Code can raise the amount owed by up to half, although the court has an express power to reduce it. Statutory interest runs on top. And where the underpayment also affected pension contributions or holiday allowance, those are separate claims.

Time limits matter more than most employees realise. A claim to periodic payments such as wages becomes time-barred five years after it fell due, so every month of delay costs a month at the far end. A written demand that meets the requirements for interrupting prescription stops the clock; a complaint made only in a meeting does not. If the employment has already ended, do not wait for the final settlement before putting the claim in writing.

Two situations call for immediate advice. The first is where the employer disputes not the amount but the applicability of the collective agreement itself, because that turns on the scope provision and often on facts about the company’s activities that need to be established properly. The second is where the employer is in financial difficulty: wage claims rank ahead of ordinary creditors but the practical answer usually lies elsewhere, as our article on an employer that goes bankrupt explains.

What the trade unions and the collective agreement parties can do

Employees are not the only ones who can enforce a collective agreement, and the parties to it have remedies an individual does not. Under the Collective Agreements Act, the organisations that concluded the agreement can claim performance and compensation from a bound employer that fails to comply, and the agreement itself may fix the amount of that compensation in advance. That is what is usually meant by the fixed penalty found in many collective agreements: a sum payable to the collective agreement parties on non-compliance, agreed in the text and not set by a court. Where the agreement has been declared generally binding, the Act on general binding declarations gives the parties a comparable claim against employers who are not their members.

Most sectors also have their own compliance body or dispute committee, and many agreements provide for an interpretation committee whose view carries weight in later proceedings. If your dispute is about what a provision means rather than whether it was applied, that route is often faster and cheaper than litigation. A trade union can also negotiate on your behalf, which frequently resolves a classification dispute without proceedings, and can bring collective action where a whole group of employees is affected.

What the Netherlands Labour Authority can and cannot do

The Netherlands Labour Authority does not police collective agreements on its own initiative, and it cannot fine an employer for paying below the collective agreement scale. Its role here is defined by article 10 of the Act on general binding declarations: where the parties to a generally binding collective agreement make it plausible that an employer is not complying, they can ask the Minister to have the Authority investigate. The Authority then examines the payroll and the working practice and produces a report of findings, which sets out facts and circumstances but expressly draws no conclusion on whether the agreement was breached. The requesting parties decide what to do with it, usually in civil proceedings.

That is not the whole picture of what the Authority enforces. Payment below the statutory minimum wage and minimum holiday allowance is a separate matter on which it does have administrative enforcement powers, as are working time, health and safety, and the rules on posted workers and the hiring out of labour. Its inspectors may enter premises, demand records and question staff and agency workers, and everyone involved must cooperate. So the practical rule for an employee is: a genuine collective agreement dispute is a civil claim, but an underpayment that also breaches the minimum wage rules is worth reporting.

A separate route exists where you were hired through a chain of employers, for example as an agency worker on a construction site. Under the chain liability rules for wages in the Civil Code, an employee who is not paid what is due can hold the client further up the chain liable, in stages and subject to conditions. It is a demanding route, but it is the answer when the direct employer has disappeared.

What to do if your employer ignores the collective agreement

Start by establishing the facts on paper. Identify the collective agreement, download the version that was in force for each period concerned, and locate the wage table and the function descriptions. Then reconstruct, month by month, what you were paid and what should have been paid, using payslips rather than memory. A calculation that a court could follow is worth more than any argument about fairness.

Put the point to your employer in writing, with the calculation attached and a reasonable deadline. Many cases are classification errors or payroll mistakes and are settled at this stage; keeping the tone factual makes that outcome more likely. If it is not resolved, involve your trade union or the compliance body named in the collective agreement, and ask about the sector dispute committee. Keep every document and every reply, and note that raising a collective agreement claim is not a ground for dismissal: an employer that responds by terminating the relationship is creating a second problem for itself.

If none of that works, the claim goes to the subdistrict court. Watch the five-year limitation period throughout, and remember that a properly worded written demand is what preserves the older months while discussions continue.
