This decision holds that at least when the employer can and does capture time worked to the exact minute, it cannot justify not paying an employee for every minute worked by relying on a facially neutral policy of rounding time to the nearest 15 minutes. California law requires payment of employees for all time worked, and disallows any de minimus exception to that requirement. Nothing in the Labor Code authorized rounding of time worked, and the efficiencies previously claimed for rounding time no longer apply in many instances since the employer, like Home Depot, can record time to the exact minute. The decision invites Supreme Court review of the issue in view of a decade of prior decisions approving neutral time rounding by employers.
