Anderson v. Mt. Clemens Pottery Co., 328 U.S. 680 (1946), is a decision by the United States Supreme Court which held that preliminary work activities, where controlled by the employer and performed entirely for the employer's benefit, are properly included as working time under Fair Labor Standards Act. The decision is known as the "portal to portal case." The Supreme Court reaffirmed Anderson v. Mt. Clemens Pottery in its 2016 ruling in Tyson Foods v. Bouaphakeo, No. 14-1146 (March 22, 2016).
