Amid word of broad corporate restructuring, workers at ClearEdge Power in South Windsor, Conn., were sent home yesterday, uncertain about what the future holds for their company or their jobs, the Hartford Courant reported today. Briefed yesterday by the company, Town Manager Matthew B. Gallagan said the fuel cell manufacturer will seek some form of bankruptcy protection. Nancy Flagg, president of the Machinist union local that represents nearly a hundred workers at the plant, said her members were sent home early Thursday, told they would be paid through the week, and were not given any more information. ClearEdge Power, headquartered in Oregon and founded in 2003, bought the South Windsor facility from United Technologies Corp. in early 2013 as part of its strategy to focus more on aerospace and building systems. Months later, ClearEdge cut about 170 out of 300 employees.
