The U.S. Supreme Court has declined to block a challenge to the constitutionality of the National Labor Relations Board (NLRB). Justice Brett Kavanaugh denied an emergency injunction requested by YAPP USA, a car parts maker, allowing the NLRB's proceedings to continue. This case, which questions the NLRB's in-house enforcement proceedings, is expected to reach the Supreme Court again as a cert petition. The challenge initially appeared on the Court's shadow docket. Additionally, the Supreme Court is set to determine the burden of proof on Fair Labor Standards Act (FLSA) exemptions, a decision that could have significant implications for labor standards.
