This document discusses reasons why women may not earn equal pay compared to men, despite doing equal work. It argues that childbearing responsibilities often interrupt women's work, as they need time off for childcare issues, school pickups, and other family duties. This leads to women accumulating skills and advancing in their careers more slowly than men who do not have these interruptions. As a result, the document claims it is not fair to expect employers to provide equal pay when the work is not equally consistent due to child-related interruptions. It also notes that women tend to advance most early in their careers before having children or later after children are raised, but are less competitive during child-rearing years.
