Ratification is a formal procedure whereby a State accepts the Convention as a legally binding instrument. Ratifying an international convention like Convention No. 190 sends an important signal to individuals and to the international community about the State’s commitment to take all measures necessary to prevent and address violence and harassment in the world of work. Moreover, Convention No. 190, as with all international labour standards, can play an important role in the design of laws and regulations, as these instruments provide authoritative guidance on law and policy. Where Conventions have been ratified, they entail international law obligations for the countries concerned (ILO 2019a).
