Shortly after the Department of Labor released its ambitious regulatory agenda, Labor Secretary Hilda Solis announced her resignation from the agency. Solis was confirmed to the post in February 2009. Under her direction, the DOL has significantly stepped up its regulatory and enforcement activities, particularly in the areas of wage and hour, worker misclassification, and whistleblower protection. Solis reportedly notified President Obama of her decision to step down on Wednesday. According to her resignation notice, Solis has decided to leave Washington to be closer to her family in California. This blog will report on any replacement nominees as soon as they are known.
