Nearly 1,400 workers have been laid off at a truck manufacturing plant in Springfield, Ohio, in one of the region’s largest recent employment losses.

The layoffs at the former Navistar truck factory took effect Wednesday, according to the Associated Press. The job cuts are significant enough to erase roughly a year of employment growth in the greater Dayton area.

The plant's future is tied to Canadian defense company Roshel, which has plans to rehire workers and expand operations at the facility. The company has been developing plans for the site as the local manufacturing sector adjusts to the change in ownership and production.

The layoffs come as Ohio communities face continued pressure from manufacturing costs, inflation and changes in industrial employment. Local workers and officials are now watching closely for details about Roshel's plans and how quickly new jobs could return to the facility.
