Wikimedia list article
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. The first convention was adopted in 1919 (as C04, shortened Night Work (Women) Convention, 1919) and revised versions were adopted in 1934 (C41, Night Work (Women) Convention (Revised), 1934) and 1948 (C89, Night Work (Women) Convention (Revised), 1948). A protocol (P89, Protocol to the Night Work (Women) Convention (Revised), 1948) to the convention was adopted in 1990 allowing for easing of the restriction under conditions. As of April 2011 the conventions had 27, 15, 46 (undenounced) ratifications respectively. The protocol was ratified 5 and denounced by 2.

Why this record matters
The phrase “wikimedia list article” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 7, 2026. The linked authority identifier is Q29965750. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1919, 1934, 1948 and 1990.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
