CAO law

When does a CAO apply?

A CAO can be declared universally binding, apply through a sector or industry, or apply through CAO terms incorporated in the employment contract. Whether a CAO applies determines a great many rights and obligations.

We map out which CAO applies, which provisions are relevant, and where there is room for a company-specific deviation.

CAO in an acquisition or reorganisation

If a company under CAO A is acquired by a company under CAO B, do employees keep their entitlement to the old terms? That depends on the transfer of undertaking and the CAO provisions involved.

We analyse transactions early so integration costs and staff claims are predictable.

Pay, allowances and compensation

Salary scale, periodic increments, allowances, travel expenses and overtime: CAO interpretation determines what is owed. Unpaid wages and penalties are a risk if the CAO is applied incorrectly.

We review payroll, CAO application and correspondence with trade unions.

Dismissal and the CAO

Some CAOs designate a sector committee for reviewing dismissals instead of the UWV. Social plans and severance payments can also be governed by the CAO.

We connect dismissal and reorganisations to CAO obligations.

Trade unions and CAO negotiation

Negotiating a new CAO, interpretation, or a company-level CAO requires strategy and knowledge of sector practice. We support both employers and employee organisations.

Disputes over CAO provisions

Disputes about scope, interpretation or compliance can go through the subdistrict court, a CAO committee, or negotiation. We assess the chances of success in proceedings and negotiate where that is faster.

Agency-worker pay and outsourced work

Where staff are hired in, equal pay with permanent employees sometimes applies. That touches on temporary work constructions and secondment.

We review contracts and actual deployment.

CAO and employment conditions regulations

Company regulations may not undermine CAO rights. We align employment conditions and individual contracts with the CAO.

Sector experience

We work with CAOs in healthcare, retail, industry, transport and services. Sector knowledge speeds up interpretation and negotiation.

CAO monitoring and compliance

Employers must apply CAO provisions correctly in payroll and HR policy. We audit compliance and help with corrections before a dispute escalates.

Disputes committee and arbitration

Some CAOs have their own committees for disputes. We guide proceedings or negotiation within those frameworks.

Acquisition due diligence and the CAO

In an M&A transaction we assess which CAO applies after closing, which claims are looming, and which warranties are needed in the purchase agreement.

Our practice in real life

Employers call us in the event of a CAO dispute, unpaid wages, or an acquisition involving a different CAO. We give immediate insight into the applicable rules and the next steps.

The employer perspective on CAO law

As an employer, you want predictable costs, manageable risks and documentation that holds up under inspection or in a dispute. We translate CAO law into concrete steps for HR, management and supervisors, with templates where that helps.

That prevents ad hoc decisions that are later challenged or lead to unnecessary proceedings.

The employee perspective on CAO law

As an employee, you want to know what you are entitled to and which steps make sense before you sign or start proceedings. We review documents, negotiate terms and guide proceedings when necessary.

Executives, professionals and skilled workers value our direct line and clear explanations, including in English.

Documentation and evidence

In CAO matters, email, minutes, contracts and arrangements all count, not just formal letters. We take stock of what the parties actually agreed and what burden of proof applies in negotiation or proceedings.

Strong documentation strengthens your position early in the process.

Works council, trade union and the CAO

Collective rules via the works council, a trade union or the CAO itself can shape how the CAO applies. We determine which procedures are mandatory and prepare advice requests or consent processes.

Mistakes in employee participation make decisions vulnerable to challenge later.

Negotiating vs litigating

Not every CAO-related dispute has to go to court. Mediation or targeted negotiation can be faster and cheaper; we give you honest advice on which route fits your goal and the relationships involved.

If proceedings are needed, we build a file that holds up before the subdistrict court or the UWV.

International and group context

International groups, holding structures and expats add secondment clauses, foreign entities and English-language contracts to the mix. We review CAO law in a group context and coordinate with foreign counsel where needed.

Due diligence and transactions

In an acquisition, merger or reorganisation, CAO law plays a role in due diligence: which claims, which contracts and which staff risks come along? We flag issues early so the purchase price and warranties are correct.

Current developments and case law

CAO law follows new legislation and case law. We keep advice and templates up to date with the current line, so you don't rely on outdated strategies that no longer hold up in 2026.

Working with HR and advisers

HR, payroll, tax advisers, occupational health services and company doctors are often involved in CAO matters. We coordinate legal steps with your internal team and external advisers, one consistent line, no conflicting advice.

First step in a CAO matter

Do you have a specific question about CAO law? Get in touch via contact or call +31 10 249 24 44. We discuss scope and planning transparently before we start, often the same working day if the matter is urgent.

See also Reorganisations and Working conditions for the broader framework.

Practical checklist for CAO law

For a CAO matter, we start with facts, goal and deadlines. We take stock of documents, talk to HR or management, and set out a first route during the intake, whether negotiation, proceedings or compliance steps.

That way you know exactly what is on your plate for the coming week.

Fees and planning

We discuss scope and fees in advance. For CAO matters we often work on a project basis or hourly rate, transparent, with no surprises on the invoice afterwards.
