Nick Fraser would regularly start his grocery picking shifts at the local Fred Meyer store at 4 or 5 a.m.
Upon arriving at the Kroger-owned chain, Mr. Fraser, who lives in Salem, Ore., would begin fulfilling online orders, zipping through aisles with a hand-held device and scanning bar codes on everything from cereal and milk to chicken and vegetables.
