The decision follows an inquiry by New York State attorney general Eric Schneiderman’s office into the legality of on-call shifts at 13 retailers, including Gap, Target Corp (TGT.N), JC Penney Co Inc (JCP.N), Abercrombie & Fitch Co (ANF.N) and TJX Cos Inc (TJX.N). On-call shifts require workers to be on call for shifts that may be canceled with little notice.
