The ILO is a big international office that tries to make work fairer around the world — pay, safety, children’s work, hours, and the right to join a union. It is not a company and not one country’s labour ministry. It started after the First World War and later became part of the United Nations family, with its main home in Geneva. The official English name uses the British spelling Labour, not Labor, though Americans still say the same letters, I-L-O. When people say “the ILO”, they mean this organisation, or a rule-book it has written that countries can agree to follow. You will see it in news about factories, migrant workers, and international meetings, not in everyday chat.
