NLRB v. Burns International Security Services (1972)
The Supreme Court ruled that a new contractor that hires a majority of its predecessor's employees must recognize and bargain with the incumbent union. But the successor is not automatically bound by the predecessor's collective bargaining agreement.
Established the successorship doctrine: a new employer who hires a majority workforce inherits the duty to bargain with the existing union.
The doctrine has governed contractor transitions for over 50 years, giving unions a foothold when contracts change hands but not guaranteeing prior terms.
If HHS hires most of Crothall's 545 workers, this doctrine requires HHS to recognize SEIU Local 32BJ and negotiate a new contract.
