Last week, President Obama re-nominated Craig Becker to serve a four-year term on the National Labor Relations Board. Becker currently sits on the NLRB as the result of a recess appointment. Senate Republicans filibustered his permanent appointment last year, and have threatened to do the same in 2011.

Becker generated controversy among employer advocacy groups due to his former service as general counsel to several union organizations. Business groups suspect him of harboring a pro-labor activist agenda, and question his objectivity on matters brought before the NLRB.

Becker's current recess appointment expires on December 31. Given the repeated filibuster threats from Republicans, his service on the NLRB beyond this date clearly remains in question.
