The National Labor Relations Board, otherwise known as the NLRB, will soon vote on whether or not employers are liable for labor violations performed by their contractors and franchisees, Reuters reported. The NLRB, an independent agency of the U.S. government, is tasked with overseeing elections for labor union representatives. A vote in favor of the proposal would essentially strengthen the “joint employer” theory that considers some companies and their contracting/staffing agencies hand-in-hand in workforce management. Businesses have widely opposed the proposal. Meanwhile, the disagreement could have big implications and ultimately be decided at the highest level: the U.S. Supreme Court.
