The Supreme Court this morning unanimously ruled for the plaintiffs — construction site security guards — in a wage and hour case. In Mendiola v. CPS Security Solutions, Inc., the court concluded, in an opinion authored by Justice Carol Corrigan, that the guards “are entitled to compensation for all on-call hours spent at their assigned worksites under their employer’s control” and that their employer cannot “exclude sleep time from [their] 24-hour shifts.”
