A class has been certified in a wage-and-hour lawsuit against Target after a federal judge rejected the company’s argument that each plaintiff’s compensable overtime calculations would be too different to resolve in a single case.

U.S. District Judge John F. Murphy of the Eastern District of Pennsylvania granted class certification against Target Corp., holding that individual differences in the total recoverable amount are less significant to the resolution of the case, “because of the central legal question and the availability of common proof in the form of expert testimony and payroll data.”
