South Korea has held the worst gender pay gap in the OECD since comparable records began in 1992. A new Human Rights Watch report, "Too Old and a Woman," based on interviews with 41 women aged 28 to 87, argues this is not a single-point failure but a compounding lifecycle extraction: each stage of a woman's career feeds disadvantage into the next, from hiring discrimination through career breaks to pension poverty. The numbers tell the compounding story cleanly. At 27, women earn 8% less than male peers. One year after university graduation, the gap is already 22%. Women's wages peak in their late 30s and then decline, while men's continue rising. By the late 50s, women earn 50% less. Park Jae-soon, 61, saw her income drop 72% — from 55 million won to 15.6 million won — when she hit mandatory retirement at 60 and shifted to part-time care work. Women received 53% of men's National Old Age Pension on average in October 2025. The structural mechanism is straightforward: caregiving remains a private, feminized responsibility. When women leave work for children, the labor market offers them back a narrow band of low-paid roles — call centers, cleaning, caregiving. J. Mi-sook, 53, had three years of experience wiped by her next employer, restarting at entry level. The longer the break, the more experience and pay women forfeit, and the less stable their employment becomes. What has changed is the surface, not the structure. Until the 1980s, "marriage-based dismissal" was legal — employers could fire women for getting married. That practice is now illegal, but as activist Min Hee Kim told DW, overt exclusion has been replaced by systemic channeling. Women's university attainment has surpassed men's since the 1980s, yet women held only 18% of management positions in 2024. Only five of 38 senior civil servants were women. HRW names the concept at work: structural discrimination so embedded that those harmed may not recognize it as discrimination at all. Kim's framing is sharper — "the work that women have traditionally done inside the home... is classified as 'work suitable for women' when it enters the labor market, and then low wages are assigned to it." The labor market doesn't just undervalue women; it takes domestic labor, repackages it as a job category, and assigns it poverty wages. The report recommends abolishing both mandatory retirement at 60 and the "peak wage" system that lets employers cut older workers' pay before retirement. South Korea's government says it will pursue raising the statutory retirement age to 65. Kim argues no single policy can fix a compounding system: equal pay enforcement, wage transparency, and public care infrastructure are all necessary simultaneously. Kim also flags limits in the report itself. Most interviewees were recruited through civic organizations and largely based in Seoul. Disabled women, migrant workers, and women outside the capital may face different and overlapping forms of age and gender discrimination. The question, she says, is not how much discrimination women face, but "which women, in what positions, become increasingly distanced from which resources and rights as they grow older."
