This article discusses challenges women face in advancing to senior leadership roles in companies. It notes that while women make up over half of entry-level professional jobs, they only hold around 14% of executive committee seats and 3% of CEO roles. Having children is identified as a major obstacle, as corporate cultures often require ultra-long hours and constant availability that can be difficult to balance with family responsibilities. The article explores some efforts by companies to implement more flexible work arrangements and examples of senior women who have managed to balance high-powered careers and motherhood. However, it concludes that truly equal representation may remain elusive given demands of the most demanding jobs.
