✅ Correct Answer: International Labour Organisation (ILO)
📌 Explanation
The ETI Base Code's nine clauses are directly grounded in the conventions of the International Labour Organisation (ILO), the United Nations agency responsible for setting international labour standards. The Base Code covers key areas including freedom of association, prohibition of forced and child labour, safe working conditions, living wages, and non-discrimination — all drawn from ratified ILO conventions.
❌ Why the other options are wrong:
United Nations (UN) — The UN has its own frameworks (e.g., UN Global Compact, UN Guiding Principles on Business and Human Rights), but the ETI Base Code is specifically derived from ILO conventions, which sit under the broader UN family.
World Trade Organisation (WTO) — The WTO focuses on international trade rules and dispute resolution, not labour standards or worker rights.
OECD — The OECD publishes Guidelines for Multinational Enterprises, which are relevant to ethical procurement, but the ETI Base Code is based on ILO conventions.
🧠 Summary
The ILO is the authoritative source for the ETI Base Code's nine clauses — procurement professionals use the Base Code as a benchmark for supplier audits and ethical codes of conduct.
