In Augustus v. ABM Security Services, Inc., the California Supreme Court stated that the Labor Code and Wage Order 4 require employers to give employees off-duty rest periods, including relieving employees of all duties and relinquishing control over how employees spend their time.  As a result, the Supreme Court stated that on-call rest periods are also prohibited, because on-call “status compels employees to remain at the ready and capable of being summoned to action.”  In Augustus, security guard employees were required “to keep their radios and pagers on during rest breaks, to remain vigilant, and to respond when needs arise.”
