Senate approves stricter rules for the temporary employment market (WTTA)

The Dutch Senate has officially adopted the Act on Admission to the Provision of Workers (WTTA). This marks a major reform in the temporary employment and payroll industry. Under the new law, only companies admitted by the new Dutch Authority for the Labour Supply Market (NAU) will be allowed to supply workers to third parties. AAme closely monitors these developments and can fully unburden organizations by guiding them through the preparation, compliance, and admission process — from risk assessment and documentation to complete application support and internal compliance setup.

Background and purpose of the WTTA

The WTTA follows the recommendations of the Advisory Committee on the Protection of Labour Migrants (the “Roemer Committee”) and aims to strengthen worker protection — particularly for labour migrants — while removing fraudulent employment agencies from the market.

According to the Dutch Ministry of Social Affairs and Employment:

“All labour migrants have the right to fair, healthy, and safe work. With this law, we take a major step forward. Only employment agencies with an official admission will be allowed to supply workers, improving both the position of labour migrants and creating a level playing field for all.”

Strict admission requirements

Companies that wish to continue supplying temporary workers must meet several stringent requirements before being admitted by the NAU, including:

• Registration with the NAU before 1 January 2027;
• Submission of a Certificate of Good Conduct (VOG);
• A financial guarantee deposit of €100,000;
• Demonstrable compliance with applicable labour, tax, and wage regulations (including the Minimum Wage Act);
• Payment of a yearly admission fee, legally capped at €3,611.

An admission will be valid for four years and subject to periodic review. Hirers may only engage personnel from admitted companies listed in the public NAU register.

Supervision and enforcement

The NAU will oversee admission procedures, gather market intelligence, and appoint inspection bodies to supervise ongoing compliance. The Dutch Labour Inspectorate will also expand by 135 FTE to strengthen enforcement capacity. Implementation timeline:

• 1 January 2027: the admission system comes into effect;
• 1 May – 30 June 2027: application window for admission;
• 1 July 2027: start of assessment by the NAU;
• 1 January 2028: enforcement begins by the Labour Inspectorate.

Non-compliant suppliers and hirers who engage non-admitted agencies risk substantial fines and possible prohibition from operating in the temporary employment market.

What this means in practice

The WTTA represents a fundamental shift in the labour supply sector. Temporary employment agencies, payroll companies, intermediaries, and hirers alike will face new obligations:

• Only admitted enterprises will be permitted to supply labour;
• Hirers must verify whether their suppliers hold valid admission (via the public NAU register);
• The NAU becomes the central body for registration, oversight, and enforcement.
