L.L. Bean says it is closing its call center in Waterville next spring. Spokeswoman Carolyn Beem says that the Freeport-based clothing and outdoor-goods retailer will consolidate its Waterville call center operations with its other call centers in Portland, Bangor and Lewiston. The Waterville center opened 12 years ago. It employs about 200 people year-round and about 500 more during the Christmas season. It is slated to close at the end of April. Beem said the year-round employees will be offered jobs at L.L. Bean’s other call centers, and about 100 may be able to work out of their homes as part of a test program.
