Labor Secretary Tom Perez came into office pledging to create good jobs and take on the economic injustice that oppresses blue-collar workers, from raising the minimum wage and restoring unpaid overtime to combatting wage theft. Luckily, the head of his Wage and Hour Division, David Weil, the author of arevelatory report on how to make the most of strategic enforcement, has moved out quite aggressively. It’s a pity that other, even more serious crimes, don’t seem to get the same priority from elsewhere in the Labor Department.
