The principal international institution that develops and enforces international labour law is the International Labour Organization (ILO), a specialised agency of the United Nations with the mandate to promote social justice and internationally recognised human and labour rights. Its main aims are to promote rights at work, encourage decent employment opportunities, enhance social protection and strengthen dialogue on work-related issues. The ILO's labour standards form the majority of the sources of international labour law.
Treaties adopted outside the ILO framework, and certain rules of customary international law also form part of international labour law.
A number of UN Human Rights Conventions create international labour law. Many of the rights and obligations conferred by UN Treaties include some that are intended to be exercised specifically in the context of employment, such as the rights to equal pay and to join and form trade unions. In addition, UN instruments confer rights that are intended to be exercised generally but also affect the employment relationship. For example, instruments that guarantee free association require that individual workers should have the right to form and join trade unions. UN Human Rights Declarations, Covenants and Conventions that form part of international labour law include:
