Mary Kay Henry

Mary Kay Henry is International President of the two-million-member Service Employees International Union (SEIU) and leads millions more in the national movement demanding Unions for All. Her leadership is rooted in a deep-seated belief that when individuals join together, they can make the impossible possible. Guided by this vision, SEIU has won major victories to improve working families’ lives by strengthening and uniting healthcare, property services, and public sector workers with other working people across the United States, Canada, and Puerto Rico. In 2010, Mary Kay Henry became the first woman elected to lead SEIU, after more than thirty years of organizing workers. By 2015, she was named one of the 100 most creative leaders by Fast Company magazine and was included in the top 50 visionaries reshaping American politics by Politico magazine for SEIU’s innovative leadership in propelling the fight for living wages embodied in the historic movement known as the Fight for $15 and a Union. She was elected a Fellow of the American Academy of Arts and Sciences in 2021.
