Thomas Perez is the nation’s newest Secretary of Labor. And given his track record of political radicalism, this ought to be more than a little troubling. Perez insists he will be even-handed in his enforcement of the law. That commitment is getting an early test. On July 23, the day of Perez’s swearing-in ceremony, two key House Republicans, John Kline (Minn.) and Phil Roe (Tenn.), wrote Perez a letter asking him to clarify the legal status of nonprofit ‘worker centers‘ that are proliferating throughout the country. Because these nonunion organizations mimic the behavior of unions, the letter stated, they ought to be subject to laws that govern unions, especially with respect to financial disclosure. Perez has yet to respond. Given that worker centers often operate as union fronts, a response would seem all the more imperative.
