SAN FRANCISCO - Factual disputes remain as to whether store managers employed by an auto parts chain primarily performed managerial duties, a Ninth Circuit U.S. Court of Appeals panel ruled May 12, reversing a trial court's grant of summary judgment in the employer's favor (Michael L. Taylor, et al. v. AutoZone, Inc., et al., No. 12-15378, 9th Cir.; 2014 U.S. App. LEXIS 8852).
