Algemene Bond Uitzendondernemingen (ABU) is the largest Dutch employer association representing staffing, payrolling, and secondment agencies. Member agencies commit to the ABU code of conduct, SNA certification, and adherence to the CAO voor Uitzendkrachten.
ABU is one of two employer parties that negotiate the national collective labour agreement for agency workers with the trade unions, alongside NBBU. Since the 2023 harmonisation, both associations apply the same CAO text, which simplifies the market for hirers. ABU also represents the sector in consultations on labour market reform, Wet WAADI, and social security policy.
For hirers, ABU membership of a staffing supplier is a quality signal that complements SNA certification. It indicates the agency has accepted sector-level standards on pay transparency, complaints handling, and responsible recruitment of migrant workers.
