Night Work Conventions are International Labour Organization Convention conventions regulating the rights of of night workers. They were specifically aimed at young persons, women or people in specific types of employment (industrial, non-industrial or bakeries) and conceived between 1919 and 1948. A more general instrument (not addressing young people however) was signed in 1990.
