This study investigates whether the rise of part-time employment serves to equalize women's professional standing or reinforces their marginalization within the labor market. Catherine Hakim and Hans-Peter Blossfeld utilize extensive longitudinal and cross-sectional data spanning from 1950 to the present to challenge existing sociological theories. By examining the sexual division of labor within the household, the authors argue that part-time work is a complex phenomenon that cannot be reduced to simple binary outcomes of equality or exclusion.

Experts recognize this work as a foundational comparative study for understanding the structural drivers of gendered labor patterns. Scholars frequently cite the text for its rigorous use of historical data to contextualize modern employment trends.
