ICJ says ILO Convention 87 protects workers’ right to strike in advisory opinion
The Facts
- The International Court of Justice issued an advisory opinion finding that workers’ right to strike is protected by ILO Convention 87.
- The court was asked by the International Labour Organization in 2023 to address an internal dispute over whether Convention 87 includes a right to strike.
- Convention 87 dates to 1948 and concerns freedom of association, including the ability of workers and employers to organize.
- The dispute had pitted unions against employer groups, with some governments also questioning whether strike rights were covered by the convention.
- The ICJ’s opinion is advisory rather than legally binding, but sources say it carries substantial weight.
- The decision matters beyond the ILO because Convention 87 has been ratified by 158 countries and is incorporated into international labour standards and some trade-related frameworks.
- The opinion does not set detailed universal rules for how strikes must be conducted under national law.
How left and right are reading this
- Both agree
- Convention 87 now carries authoritative support for protecting strike rights, while still leaving national governments without a detailed universal rulebook for how strikes must be conducted under domestic law.
- They split on
- Whether the story is mainly about securing a meaningful international guarantee for workers’ collective power, or about affirming that even a weighty international opinion should stop short of dictating national strike rules.
