Stichting Naleving CAO voor Uitzendkrachten (SNCU) is the bipartite foundation established by unions and employer associations to enforce compliance with the CAO voor Uitzendkrachten, the collective labour agreement that governs agency workers in the Netherlands. It investigates signals of underpayment, incorrect scale classification, or other breaches.
SNCU can audit agency payroll records, interview workers, and impose contractual penalties on agencies that are found to be non-compliant. Complaints may be filed anonymously by workers, hirers, or competitors, and SNCU coordinates with the Belastingdienst and the Nederlandse Arbeidsinspectie where wider offences are suspected.
For hirers, SNCU findings against a staffing supplier are a material reputational and legal risk indicator. Selecting SNA-certified agencies and verifying inlenersbeloning calculations remains the most effective way to stay out of SNCU enforcement procedures.
