The Labour Inspection Convention, 1947 , also referred to as ILO Convention no. 81 or C081, is a governance convention adopted by the International Labour Organization on July 11, 1947. It entered into force on April 7, 1950 and has been ratified by 148 of the 186 ILO member states as of 2021. The convention sets out principles concerning the organization, functions, and operation of labour inspection systems to ensure enforcement of national laws related to working conditions and worker protections in the commercial and industrial sectors. A Protocol adopted in 1995 expands the coverage of Convention No. 81 to non-commercial or industrial sectors.
