Final answer:
The Second Shift by Hochschild does not provide an exact duration of the leisure gap during her research period but focuses on the concept that women's leisure time was significantly less than men's due to the additional household responsibilities.
Step-by-step explanation:
According to The Second Shift by Arlie R. Hochschild and Anne Machung, the book does not specify the exact duration of the leisure gap during the time of Hochschild's research. However, the concept of the leisure gap relates to the difference in leisure time between men and women, largely due to the additional responsibilities women assume from the "second shift." This term refers to the housework and childcare duties that many women attend to after completing their paid workday.
In the context of the 1980s, when Hochschild conducted her research, it was noted that despite working similar hours to their husbands, women were still doing the majority of the household labor, which drastically reduced their leisure time compared to men. The overarching theme of the book is the work-life balance challenges faced by working parents, particularly women.
