For many Americans, Labor Day means hanging out by the pool, hitting up some holiday sales, having a barbecue or heading off on one last vacation before summer ends and school begins. Labor Day has become so synonymous with fun and relaxation that many forget it was created to celebrate work—specifically the labor movement.

Given its reason for being, Labor Day 2014 is an appropriate time to reflect on some of the important developments that have occurred this year at the National Labor Relations Board—the federal agency most closely connected with the fate of unions in the U.S. It’s been a busy year for the agency, in which it’s gotten a new general counsel, Richard Griffin Jr., been the focus of a major decision at the U.S. Supreme Court, and issued a wide variety of interesting decisions and briefs.
