PCC Structurals goes with the material in Chapter 6 on determining an appropriate bargaining unit. In PCC Structurals, the NLRB overturned the 2011 Specialty Healthcare case, which made it easier for unions to petition for smaller bargaining units. In PCC Structurals–especially in combination with the subsequent The Boeing Co. (2019)–the NLRB made it easier for employers to insist on a larger bargaining unit.
Add the attached edited PCC Structurals decision to Chapter 6, Section 3, which starts on page 364.
