Despite an employment rate of 76.6% for women in Germany, significant issues persist with regard to the labour market situation of women in the country. These include the prevalence of part-time work, the under-representation of women in senior management positions and the existence of pay gaps. This article employs data from the German Statistical Office spanning the period from 2000 to 2022 to examine the growth in part-time employment among women and its ramifications. The paper demonstrates that part-time work is a prevalent phenomenon in female-dominated sectors such as health and education. This is driven by a combination of economic conditions, the necessity to reconcile work and family life, and legal regulations. This situation consequently results in women facing lower remuneration and constrained career prospects. The necessity to balance work and family responsibilities represents a significant challenge for women, impeding their career development and negatively impacting their job performance and workplace commitment. These dynamics serve to perpetuate gender inequalities in the labour market, thereby preventing women from realising their full potential at work. This article makes a significant contribution to the existing literature on the relationship between part-time work and gender inequalities in the German labour market by providing a detailed analysis of this complex relationship. The article offers valuable insights into the potential of legal regulations, such as the Temporary Part-Time Work Act enacted in 2019, to alleviate the adverse effects of part-time work on women. The research is distinctive in its comprehensive examination of the socio-economic dynamics of part-time work, its legal framework, and its impact on gender equality, based on an extensive data analysis conducted over an extended period. By offering a detailed and nuanced understanding of these issues, the study draws attention to the ongoing challenges women face in the labour market and suggests potential policy interventions to promote gender equality. This article emphasises the necessity for targeted measures to facilitate women's career progression and offset the adverse consequences of part-time employment, thereby contributing to a more equitable labour market.
