After 25 years with San Francisco’s Legal Aid Society-Employment Law Center, Patricia Shiu is heading to Washington, D.C., to take a post with the U.S. Department of Labor.

Shiu, who said she got a call from the White House the day after Easter, will start as director of the Office of Federal Contract Compliance Programs in September. The office is responsible for enforcing laws that prohibit discrimination and that require affirmative action by companies contracting with the federal government.
