World Court Says ILO Freedom Of Association Treaty Covers Right To Strike
The International Court of Justice (ICJ) ruled on May 21, 2026 that the ILO Freedom of Association Convention protects workers' right to strike, a finding with global legal and labor implications.[1]
All 14 judges in the advisory opinion said the convention's guarantees of freedom of association cover strikes even though the treaty does not use the word "strike".[1] The court stressed that its advisory opinion does not set out the precise scope or legal conditions for striking and said governments may lawfully impose certain restrictions.[1]
The 1948 ILO Freedom of Association and Protection of the Right to Organize Convention has been ratified by 158 countries and is incorporated into UN, OECD and other international labor and trade standards.[1] The United States belongs to the International Labour Organization but has not ratified the 1948 convention.[1]
Observers say the advisory opinion could influence national courts and labor policy in countries that ratified the treaty. Concrete effects will depend on how national and regional courts interpret and apply the ICJ's guidance.
