Union members and California-based Serious Energy must now work together to find new ownership to keep the plant open, a union news release said.
After being told by local management that the window factory would close immediately, workers at the former Republic Windows and Doors plant demanded time to save their jobs by finding a buyer, the release said.
The union, United Electrical Radio and Machine Workers of America, staged the sit-in after refusal for more time by management, the release said.
In 2008, union members at the same factory, then owned by Republic Windows and Doors, occupied and won $1.75 million in wages and benefits owed from Bank of America, the release said.
