Secretary of Labor Hilda Solis has announced her resignation ahead of President Obama’s second term beginning later this month. Solis is the first Latina to lead a federal agency and was known for her public support of unions, pushing measures including the Employee Free Choice Act, which would have removed barriers to unionizing workers. In a statement, AFL-CIO President Richard Trumka praised her tenure, saying: “[Solis] brought urgently needed change to the Department of Labor, putting the U.S. government firmly on the side of working families.”
