Sutherland Global Services Ltd. has settled a class-action lawsuit alleging it failed to pay its call center telemarketers the overtime they were owed. The lawsuit, filed in 2005 in U.S. District Court for the Western District of New York, was brought by a pair of Rochester employees of the Perinton-based business process outsourcing company. The suit eventually grew to ten named employees and hundreds of unnamed workers, who claimed they regularly worked more than 40 hours a week but were not paid overtime. Sutherland agreed in July to a $4 million settlement to be divided among members of the class. U.S. District Judge David G. Larimer has given final approval to the settlement, which winds up the litigation.
