A Supreme Court decision last month tossed out hundreds of previously settled cases by the National Labor Relations Board. Now, as the government agency scrambles with its do-over, companies across the nation may be forced to share in its pain, potentially having to undergo the arduous process of revisiting their employment policies and creating new ones under a cloud of uncertainty.

The troublesome vacuum in labor law results from a June 26 opinion issued by the Supreme Court in the matter of NLRB v. Noel Canning. The nation’s highest court determined that recess appointments by the Obama Administration to the board were improper, invalidating hundreds of the board’s decisions.
