Nederlandse Bond van Bemiddelings- en Uitzendondernemingen (NBBU) is the Dutch trade association that represents primarily small and mid-sized staffing, recruitment, and secondment agencies. Members commit to SNA certification, a code of conduct, and compliance with the CAO voor Uitzendkrachten.
NBBU is, together with ABU, an employer party to the national agency-worker CAO. Since 2023 the two associations apply a single harmonised CAO text, which removed long-standing differences between their members. NBBU also provides legal helpdesk support, training, and sector advocacy to its members.
For hirers, NBBU membership functions as a quality marker alongside SNA registration. It signals that the agency operates under recognised sector standards on pay, complaints, and worker welfare, which is relevant when selecting suppliers for flexible labour.
