The Conventions concerning Employment of Women during the Night are conventions drafted by the International Labour Organization (ILO) which prohibit women from performing industrial work during the night.
In the 1934 convention a provision is included allowing work in managerial functions, while in 1948 the possibility suspension of the convention was included "when in case of serious emergency the national interest demands it".
All conventions entered into force upon or 12 months after the ratification of two ILO member states.
The revised conventions and the protocol entered into force 12 months after ratification.
Today, these conventions are often perceived as discriminatory and in contradiction with the equality principle, and as such have been denounced by several countries.
