The research that was commissioned to provide material for Report VI on the ILO’s extensive collaboration on gender equality with the UN family within the context of "Delivering as One" and UN reform forms the basis of this working paper. This paper focuses on ILO contributions/actions which strengthen UN work by highlighting gender dimensions in the world of work; and provides some historical perspective as well as illustrations of the UN using the ILO’s knowledge and advice on women’s empowerment and gender equality.
