CIGNA Corp. said that it will close its claim-processing center in Loughrea, Ireland, in June and cut all 180 jobs there roughly six years after the company began expanding the office. The layoffs are considered part of the 1,000 U.S. jobs CIGNA is cutting because the Irish employees process claims from U.S.-based customers. CIGNA is automating and outsourcing the work from Ireland to vendors to reduce costs.
