New rules for the temporary employment sector: avoid fines  

There is now final clarity regarding the implementation of the Temporary Agency Work Admission Act (Wtta). The Dutch Ministry of Social Affairs and Employment has established the timeline: the law will officially come into effect on January 1, 2027. The goal is clear: to create a transparent temporary employment market in which everyone operates fairly and according to the rules. 

At Opus Recruitment, we closely follow these developments. We stand for quality and good employment practices. Whether you are a business hiring flexible workers or a temporary worker employed through us, we have summarized the key points for you below. 

 

 

What is the Wtta? 

The Wtta introduces a new admission system for the temporary employment sector. From January 1, 2027, temporary employment agencies may only supply workers if they have received official approval. 

To obtain and maintain this approval, agencies will be strictly monitored for compliance with collective labour agreements, correct salary payments, timely tax payments, and proper administration. 

 

 

What does this mean for clients? 

For companies working with flexible staff, the Wtta mainly provides additional security and peace of mind. From the start of enforcement, hirers will be required to work only with officially approved temporary employment agencies. 

Security in advance: You immediately know you are working with a transparent and financially healthy partner.  

Fewer administrative concerns: By choosing a certified agency now, you avoid future adjustments or compliance risks.  

Focus on your business: Daily operations remain unchanged; the agency takes care of the legal and administrative matters.  

 

 

What does this mean for temporary workers? 

For you as a flexible worker, this law is good news. The Wtta protects your position in the labour market and creates a fair playing field. 

Fair pay: You can be sure you receive the salary you are entitled to under the applicable collective labour agreement.  

Safe working environment: There will be increased supervision of healthy and safe working conditions at client companies.  

Reliable foundation: You work through an agency that has its financial and administrative affairs properly organized.
