According to Duncombe and Marsden, what concept describes women's contribution of domestic and emotional labor in addition to their full-time jobs?

The concept described by Duncombe and Marsden regarding women's contribution of domestic and emotional labor alongside their full-time jobs is known as the "triple shift." This term refers to the idea that many women undertake three types of responsibilities: paid work, domestic work (such as household chores), and emotional labor (the management of emotions and support within family dynamics).

The significance of the triple shift lies in its recognition of the increasing demands placed on women due to societal expectations, where they are often expected to excel in their careers while simultaneously managing their households and providing emotional support to family members. This concept highlights the complexities of women's roles and the unequal division of labor within households, emphasizing that even as they participate in the workforce, women frequently bear an additional burden in their personal lives.

In contrast, the double shift primarily focuses on the work-life balance of women juggling paid employment and domestic responsibilities without explicitly addressing the emotional labor component. Emotional labor is a critical aspect but does not encompass the entire scope of the three areas indicated by the triple shift. Family function relates more broadly to the roles and responsibilities within family dynamics rather than specifically addressing the labor division women experience.
