What is the purpose of the National Labor Relations Board? Is the federal agency meant to be neutral arbiter of labor laws? Or is meant to be an advocate for Big Labor, helping to ensure it organizes the U.S. workforce? Under President Obama, the NLRB has chosen the latter.

That was the only conclusion District Judge Arthur Schwab said he could draw from the “overly broad and unfocused” subpoenas the board’s general counsel had submitted in the case NLRB v. University of Pittsburgh Medical Center & UPMC Presbyterian Shadyside.
