International Labour Organization

Introduction

The International Labour Organization (ILO) is a specialised agency of the United Nations concerned with labour, employment and social justice.

It is unique among major international organisations because of its tripartite structure, under which representatives of:

• governments;
• employers;
• workers

participate in its decision-making.

The ILO develops international labour standards through Conventions and Recommendations, promotes decent work, supports social protection and employment policies, and supervises the implementation of international labour standards.

The ILO is particularly important in international law because it demonstrates how international organisations can develop international standards through institutional cooperation and treaty-making.

Establishment of the ILO

The ILO was established in 1919 in the aftermath of the First World War.

It was originally associated with the League of Nations.

The organisation was founded on the recognition that lasting peace requires social justice and acceptable conditions of labour.

The ILO later became the first specialised agency associated with the United Nations system in 1946.

Its headquarters are in Geneva, Switzerland.

Constitutional Basis

The constitutional framework of the ILO is primarily contained in:

• the ILO Constitution, 1919;
• the Declaration of Philadelphia, 1944;
• subsequent amendments and instruments.

The Declaration of Philadelphia was incorporated into the ILO Constitution in 1946 and remains particularly important for understanding the organisation’s objectives.

Fundamental Principle of the ILO

A central principle of the ILO is:

“Labour is not a commodity.”

The organisation recognises that economic development should be accompanied by:

• social justice;
• decent working conditions;
• protection of workers;
• respect for fundamental labour rights.

Objectives of the ILO

The ILO seeks to promote:

• social justice;
• decent work;
• employment opportunities;
• labour rights;
• social protection;
• improved working conditions;
• equality at work;
• freedom of association;
• collective bargaining;
• elimination of forced labour;
• abolition of child labour;
• elimination of discrimination in employment.

ILO and International Peace

The ILO’s constitutional philosophy connects social justice with lasting peace.

The underlying idea is:

Poor working conditions + social injustice

↓

Social instability

↓

Threat to lasting peace

Therefore:

Social Justice

↓

Fair Labour Standards

↓

Social Stability

↓

Lasting Peace

Tripartite Structure

The most distinctive feature of the ILO is its tripartite structure.

Three groups participate in the organisation:

Governments

Represent the interests and policies of Member States.

Employers

Represent employers and business interests.

Workers

Represent workers and trade unions.

This means the ILO is not simply an organisation in which governments alone make decisions.

Importance of Tripartism

Tripartism allows labour standards to be developed through participation of the principal actors affected by them.

Therefore:

ILO

↓

Government + Employers + Workers

↓

International Labour Standards

This distinguishes the ILO from most other international organisations.

Principal Organs of the ILO

The ILO has three principal institutional bodies:

• International Labour Conference;
• Governing Body;
• International Labour Office.

International Labour Conference

The International Labour Conference (ILC) is the principal policy-making and standard-setting body of the ILO.

It is sometimes described as the international parliament of labour.

It meets annually.

Each Member State is represented by a delegation consisting of:

• two government delegates;
• one employers’ delegate;
• one workers’ delegate.

Each delegate has an independent vote.

Functions of the International Labour Conference

The Conference:

• adopts international labour standards;
• adopts Recommendations;
• discusses major labour issues;
• approves the ILO budget;
• determines broad ILO policies;
• reviews important labour developments.

Voting in the International Labour Conference

The tripartite structure is reflected in voting.

Government, employer and worker delegates participate independently.

This prevents governments from exercising exclusive control over the development of international labour standards.

Governing Body

The Governing Body is the executive body of the ILO.

It:

• determines ILO policy;
• establishes the programme and budget;
• prepares the agenda of the International Labour Conference;
• supervises the work of the International Labour Office;
• oversees the organisation’s activities.

The Governing Body also has a tripartite composition.

International Labour Office

The International Labour Office is the permanent secretariat of the ILO.

It provides:

• research;
• technical assistance;
• administrative support;
• preparation of reports;
• assistance in drafting labour standards;
• support for ILO programmes.

It is headed by the Director-General.

International Labour Standards

One of the most important functions of the ILO is the development of international labour standards.

The principal forms are:

Conventions

ILO Conventions are international treaties adopted by the International Labour Conference.

They become legally binding on a State when that State ratifies the Convention, subject to its terms.

Therefore:

ILO Convention adopted

↓

State ratification

↓

International legal obligations for that State

Recommendations

ILO Recommendations provide guidance on labour policy and legislation.

They generally do not create treaty obligations in the same way as ratified Conventions.

They may:

• supplement Conventions;
• provide policy guidance;
• recommend legislative or administrative measures.

Convention vs Recommendation

Convention	Recommendation
International labour treaty	International labour standard/guidance
Can be ratified	Not subject to ratification in the same manner
Binding on ratifying States	Generally non-binding
Creates international obligations for ratifying States	Provides guidance
Requires implementation and supervision	Influences labour policy and legislation

Adoption of an ILO Convention

The basic process can be understood as:

Labour Issue Identified

↓

ILO Study and Consultation

↓

International Labour Conference

↓

Adoption of Convention

↓

Submission to Competent National Authority

↓

Ratification by State

↓

Implementation

↓

ILO Supervision

Ratification

Adoption by the International Labour Conference does not automatically make a Convention binding on every ILO Member State.

Ratification is crucial.

Once a State ratifies a Convention, it assumes the international obligations contained in that instrument, subject to the Convention’s terms.

Submission to Competent Authorities

An important feature of the ILO constitutional system is that States are required to submit adopted Conventions and Recommendations to their competent national authorities for consideration.

This obligation exists even where the State ultimately decides not to ratify a Convention.

Fundamental Principles and Rights at Work

The ILO has identified fundamental principles and rights at work.

The 1998 Declaration on Fundamental Principles and Rights at Work, as amended in 2022, recognises fundamental principles concerning:

• freedom of association and effective recognition of the right to collective bargaining;
• elimination of forced or compulsory labour;
• effective abolition of child labour;
• elimination of discrimination in respect of employment and occupation;
• a safe and healthy working environment.

The inclusion of a safe and healthy working environment as a fundamental principle was an important development in 2022.

Fundamental ILO Conventions

The ILO’s fundamental conventions correspond to the fundamental principles and rights at work.

Important areas include:

Freedom of Association

Protection of workers’ and employers’ organisations.

Collective Bargaining

Recognition of collective bargaining rights.

Forced Labour

Elimination of forced or compulsory labour.

Child Labour

Abolition and elimination of the worst forms of child labour.

Non-Discrimination

Equality of opportunity and treatment in employment.

Occupational Safety and Health

Promotion of a safe and healthy working environment.

Freedom of Association

Freedom of association is a fundamental ILO principle.

It includes the ability of workers and employers to form and join organisations of their choosing, subject to applicable international standards.

This is closely connected with:

• trade unions;
• collective bargaining;
• workers’ representation.

Collective Bargaining

Collective bargaining involves negotiation between:

Employers

and

Workers / their organisations

concerning:

• wages;
• working conditions;
• employment terms;
• workplace rights.

The ILO promotes collective bargaining as an important mechanism of industrial relations.

Elimination of Forced Labour

The ILO seeks to eliminate forced or compulsory labour.

Important ILO instruments include:

• Forced Labour Convention, 1930;
• Abolition of Forced Labour Convention, 1957.

Abolition of Child Labour

The ILO has developed important standards concerning child labour.

Major instruments include:

• Minimum Age Convention, 1973;
• Worst Forms of Child Labour Convention, 1999.

Elimination of Discrimination

The ILO promotes equality in employment and occupation.

The Discrimination (Employment and Occupation) Convention, 1958 is a major instrument in this field.

Safe and Healthy Working Environment

Following the 2022 amendment to the ILO’s fundamental principles, a safe and healthy working environment is recognised as a fundamental principle and right at work.

Important conventions include:

• Occupational Safety and Health Convention, 1981;
• Promotional Framework for Occupational Safety and Health Convention, 2006.

Decent Work

The concept of decent work is central to contemporary ILO policy.

It involves:

• productive employment;
• fair income;
• workplace security;
• social protection;
• rights at work;
• social dialogue;
• equality of opportunity.

The basic idea is:

Employment

Rights

Social Protection

Social Dialogue

=

Decent Work

Social Dialogue

Social dialogue refers to interaction between:

• governments;
• employers;
• workers.

It may include:

• consultation;
• negotiation;
• collective bargaining;
• cooperation.

It is a fundamental practical expression of the ILO’s tripartite model.

ILO Supervisory System

One of the most important aspects of the ILO is its system for supervising implementation of international labour standards.

Supervision generally involves:

• reporting by States;
• examination of reports;
• observations and comments;
• representations;
• complaints;
• expert review;
• Conference-level consideration.

Committee of Experts

The Committee of Experts on the Application of Conventions and Recommendations (CEACR) is an independent body of legal and social experts.

It examines:

• reports submitted by governments;
• implementation of ratified Conventions;
• national legislation and practice.

It issues:

• observations;
• direct requests.

Its conclusions are influential in the ILO supervisory system.

Committee on the Application of Standards

The Committee on the Application of Standards is a tripartite committee of the International Labour Conference.

It examines cases involving the application of labour standards and discusses serious or significant implementation issues.

Thus:

CEACR → Expert legal/technical examination

Conference Committee → Tripartite political/institutional examination

Representations

Under the ILO Constitution, workers’ or employers’ organisations may make a representation alleging that a Member State has failed to secure effective observance of a ratified Convention.

This provides a mechanism beyond ordinary government reporting.

Complaints

The ILO Constitution also provides for a complaint procedure concerning failure to comply with a ratified Convention.

A complaint may be brought through the institutional mechanisms established under the Constitution.

The Committee on Freedom of Association also plays a major role in complaints concerning freedom of association, including in circumstances where the relevant State has not ratified the relevant Conventions.

Committee on Freedom of Association

The Committee on Freedom of Association (CFA) examines complaints concerning violations of freedom of association and trade union rights.

Its importance lies in its ability to examine such complaints as part of the ILO’s supervisory framework.

Article 33 Mechanism

A particularly strong provision is Article 33 of the ILO Constitution.

Where a Member State fails to comply with recommendations of a Commission of Inquiry or a decision of the International Court of Justice concerning a complaint, the Governing Body may recommend that the International Labour Conference take measures to secure compliance.

This provides an exceptional institutional enforcement mechanism.

ILO and International Court of Justice

The ILO Constitution recognises a role for the International Court of Justice (ICJ) in certain disputes.

Questions concerning interpretation of the ILO Constitution may be referred to the ICJ under the applicable constitutional framework.

The ICJ can therefore contribute to resolving legal questions concerning ILO constitutional arrangements.

ILO and United Nations

The ILO became part of the UN specialised-agency system in 1946.

Under the UN Charter, specialised agencies have relationships with the UN through appropriate agreements and coordination mechanisms.

ECOSOC plays an important role in coordinating the activities of specialised agencies.

Therefore:

ILO

↓

Specialised Agency

↓

UN System

↓

Coordination through ECOSOC and other mechanisms

ILO Legal Personality

The ILO possesses international legal personality as an international organisation.

Its constitutional instruments establish its:

• institutional structure;
• functions;
• powers;
• international responsibilities.

As a specialised international organisation, its powers are governed by the principle of speciality.

ILO and International Law

The ILO contributes to international law through:

• international labour treaties;
• Recommendations;
• supervisory practice;
• international standards;
• technical cooperation;
• institutional decisions.

Its Conventions are particularly important because ratification creates treaty obligations for the States concerned.

ILO and Human Rights

Labour rights overlap significantly with international human rights law.

Examples include:

• freedom of association;
• prohibition of forced labour;
• prohibition of child labour;
• equality and non-discrimination;
• safe working conditions.

The ILO therefore makes an important contribution to the international protection of human rights.

ILO and Sustainable Development

The ILO’s work is closely linked with the Sustainable Development Goals, particularly:

• SDG 8 – Decent Work and Economic Growth;
• poverty reduction;
• gender equality;
• reduced inequalities.

The concept of decent work is central to the international development agenda.

ILO and Social Justice

The ILO’s central philosophy can be summarised as:

Economic progress

without

social justice

is insufficient for lasting peace and sustainable development.

The organisation therefore attempts to balance:

Economic Development + Labour Rights + Social Protection

Declaration of Philadelphia

The Declaration of Philadelphia, 1944 is one of the most important constitutional documents of the ILO.

It reaffirmed principles including:

• labour is not a commodity;
• freedom of expression and association are essential to sustained progress;
• poverty anywhere constitutes a danger to prosperity everywhere;
• all human beings have the right to pursue material well-being and spiritual development in conditions of freedom and dignity.

The Declaration significantly influenced the modern philosophy of international labour law.

Important ILO Conventions

Some particularly important Conventions include:

Convention	Subject
C29	Forced Labour
C87	Freedom of Association
C98	Right to Organise and Collective Bargaining
C100	Equal Remuneration
C105	Abolition of Forced Labour
C111	Discrimination in Employment and Occupation
C138	Minimum Age
C182	Worst Forms of Child Labour
C155	Occupational Safety and Health
C187	Promotional Framework for Occupational Safety and Health

These instruments are important for understanding the development of international labour standards.

ILO and Trade Unions

The ILO recognises the importance of workers’ organisations.

Trade unions participate in the ILO’s tripartite structure through worker representatives.

The ILO also promotes:

• freedom of association;
• collective bargaining;
• protection of workers’ representatives.

ILO and Employers’ Organisations

Employers are not merely regulated subjects within the ILO framework.

Employers’ organisations participate directly in:

• standard-setting;
• policy discussions;
• governance;
• supervision.

This is a defining feature of tripartism.

ILO During Economic Crises

The ILO can provide policy guidance during:

• economic recessions;
• employment crises;
• global disruptions;
• labour-market transitions.

It promotes policies aimed at maintaining employment and social protection while respecting labour standards.

ILO and Globalisation

Globalisation has created labour-law challenges involving:

• multinational enterprises;
• global supply chains;
• informal employment;
• migrant workers;
• platform work;
• technological change.

The ILO develops standards and policies aimed at addressing these changing labour conditions.

ILO and Migrant Workers

The ILO has developed standards concerning migrant workers and their employment conditions.

The objective includes:

• equality of treatment;
• protection against exploitation;
• fair employment conditions;
• social security protection.

ILO and Indigenous and Tribal Peoples

The Indigenous and Tribal Peoples Convention, 1989 (No. 169) is an important ILO instrument concerning indigenous and tribal peoples.

It addresses issues including:

• consultation;
• participation;
• cultural integrity;
• land and resource interests;
• employment rights.

ILO and International Labour Law

The ILO is the most important specialised international institution in the field of international labour law.

Its contribution can be understood through:

Standard Setting

↓

Ratification

↓

National Implementation

↓

↓

International Cooperation

Importance of the ILO

Development of International Labour Standards

The ILO has created an extensive body of international labour standards.

Protection of Workers

It promotes minimum standards of treatment and working conditions.

Social Justice

It connects labour rights with broader social justice.

Tripartite Governance

It uniquely incorporates governments, employers and workers into institutional decision-making.

International Cooperation

It provides a forum for States and social partners to cooperate on labour issues.

Human Rights

Many ILO standards overlap with fundamental human rights.

Limitations of the ILO

Ratification

Many ILO Conventions depend upon State ratification for treaty obligations.

National Implementation

Even after ratification, effective implementation depends heavily upon domestic institutions.

Supervisory Rather Than Conventional Enforcement

The ILO’s supervisory system relies substantially on reporting, examination, dialogue and institutional pressure rather than a general coercive enforcement mechanism.

Changing Labour Markets

Technological change, platform work and global supply chains create new regulatory challenges.

Conclusion

The International Labour Organization is a unique and highly significant institution in international law. Established in 1919 and incorporated into the UN specialised-agency system in 1946, it has played a central role in developing international labour standards and promoting social justice.

Its most distinctive characteristic is its tripartite structure, bringing together governments, employers and workers in the process of international standard-setting and governance.

The ILO develops international labour standards principally through Conventions and Recommendations. Ratified Conventions create international legal obligations for the States concerned, while Recommendations provide guidance for national labour policy and legislation. Its sophisticated supervisory system, including the Committee of Experts and the Committee on Freedom of Association, provides mechanisms for monitoring implementation.

The ILO’s constitutional philosophy, particularly reflected in the Declaration of Philadelphia, connects decent working conditions and social justice with lasting international peace.

For examinations, remember the core formula:

ILO → 1919 → Geneva → UN specialised agency (1946) → Tripartism → Conference + Governing Body + Office → Conventions + Recommendations → Labour Standards → Social Justice.
