The 2030 Agenda has, as one of its goals, Sustainable Development Goal (SDG) No. 8, which consists of promoting “sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all”. To understand this, it is necessary to study the concept of decent work and its pillars, such as social dialogue, rights at work, social protection and employment creation. With that in mind, the present article analyses the importance of promoting decent work to mitigate precarious work performed by women. Therefore, the research is guided by dogmatic investigation, using bibliographic study to explain the construction of development – and sustainable development, what decent work, precarious work and women labour are. Although the paper does not exhaust the topic, it stresses the importance of the promotion of decent work and of considering unpaid domestic work to protect women from precarious work, by a systematic reading of SDG No. 8 and No. 5, without ignoring the other SDGs, like 10 and 16, to encourage more equal policies.
