Kim founded and served as the Executive Director Interfaith Worker Justice, the nation's largest network of people of faith engaging in local and national actions to improve wages, benefits and conditions for workers, especially those in the low-wage economy from 1996 until 2015. As executive director, she helped build interfaith groups and workers centers around the nation. Kim was named one of 14 faith leaders to watch in 2014 by the Center for American Progress, and one of Utne Reader's "50 Visionaries Who Are Changing Your World" in 2009.
Kim is the author of Wage Theft in America: Why Millions of Working Americans Are Not Getting Paid - And What We Can Do About It, the first and only book to document the wage theft crisis in the nation and propose practical solutions for addressing it. The first edition came out in 2008 and the revised edition in 2011. The book and Kim’s extensive speaking on the subject helped coin the phrase “wage theft” and has helped get the issue of wage theft on the national radar.
Prior to Interfaith Worker Justice, Kim was a trainer for the Midwest Academy, and Director of Organizing for Bread for the World. She is co-author of Organizing for Social Change, the best-selling organizing manual in the country.
Kim is the Choir Director at Good News Community Church, a multicultural congregation in the Rogers Park neighborhood of Chicago. Kim was married for 31 years to Stephen Coats, a tireless advocate for workers in Central and South America who died unexpectedly in 2013. She has two "almost perfect" twin sons, Eric and Benjamin, who are away at college.
