ILO Core Labour Conventions

The International Labour Organization's eight fundamental conventions establish the minimum standards for core labour rights that are universally recognised as essential to decent work and human dignity.

The ILO, founded in 1919 and now a specialised agency of the United Nations, has adopted 190 conventions covering a wide range of labour issues. However, eight conventions are designated as "fundamental" and form the bedrock of international labour standards. These conventions address four categories of principles: freedom of association and collective bargaining, elimination of forced labour, abolition of child labour, and elimination of discrimination in employment.

The Eight Fundamental Conventions

Freedom of Association and Collective Bargaining is addressed by Convention No. 87 (Freedom of Association and Protection of the Right to Organise, 1948) and Convention No. 98 (Right to Organise and Collective Bargaining, 1949). These conventions guarantee workers' and employers' rights to establish and join organisations of their choosing without prior authorisation, and protect workers against anti-union discrimination.

Elimination of Forced Labour is covered by Convention No. 29 (Forced Labour, 1930) and Convention No. 105 (Abolition of Forced Labour, 1957). These prohibit all forms of forced or compulsory labour, including as a means of political coercion, labour discipline, punishment for strikes, racial discrimination, or economic development.

Abolition of Child Labour is addressed by Convention No. 138 (Minimum Age, 1973) and Convention No. 182 (Worst Forms of Child Labour, 1999). Convention 138 sets the general minimum working age at 15 years (13 for light work), while Convention 182 calls for immediate elimination of the worst forms of child labour including slavery, trafficking, debt bondage, and hazardous work.

Elimination of Discrimination is covered by Convention No. 100 (Equal Remuneration, 1951) and Convention No. 111 (Discrimination in Employment and Occupation, 1958). These require equal pay for work of equal value regardless of sex, and prohibit discrimination based on race, colour, sex, religion, political opinion, national extraction, or social origin.

Relevance to ESG Reporting

The ILO fundamental conventions are referenced extensively across ESG frameworks. The GRI Standards (particularly GRI 407-409) directly map to ILO conventions. The UN Global Compact's labour principles are derived from the ILO Declaration on Fundamental Principles and Rights at Work. ESRS S1 (Own Workforce) and S2 (Workers in the Value Chain) require disclosure on alignment with ILO standards. Companies conducting human rights due diligence under the UNGPs are expected to assess risks against these conventions.

The 1998 Declaration

The ILO Declaration on Fundamental Principles and Rights at Work (1998, amended 2022) establishes that all ILO member states have an obligation to respect, promote, and realise the principles in the fundamental conventions, regardless of whether they have ratified them. The 2022 amendment added occupational safety and health as a fifth category of fundamental principles, elevating Conventions No. 155 and No. 187 to fundamental status.
