Volvo Trucks North America announced permanent layoffs of 650 hourly employees in March and April at its New River Valley plant in Dublin, Va., according to published reports.

The will sideline 40 percent of the truck assembly plant's remaining workforce. This follows a layoff of about 1,000 workers at the plant last May.

Last August, restructuring plans for Volvo sister company Mack were announced that would transfer assembly of all Mack highway vehicles from the Dublin plant to the Mack plant in Macungie, Pa.
