DTNA has announced it will lay off about 1,240 workers across its North American production facilities in response to sustained reductions in truck orders.

Calling it a workforce adjustment, DTNA will lay off workers at its Mount Holly, N.C., Gastonia, N.C., Portland, Ore., and Santiago, Mexico, facilities. There are currently no plans for reductions at the company’s facilities in Cleveland, N.C., and Saltillo, Mexico.

The company has seen a 15% decrease in Class 6-8 retail sales compared with last year’s robust numbers. However, it expects the low orders and diminished build rate to be temporary.

The workers to be laid off as part of this reduction will have first rights to be recalled when production is able to sustain a higher build rate, according to DTNA.

The last day of work at the Portland and Mount Holly facilities for laid-off workers will be July 1; the last day at the Gastonia Facility will be June 24; and the last day at the Santiago plant will be June 29.

The workforce reduction will impact approximately 600 workers at the Mount Holly facility; 270 workers at the Santiago facility; 200 workers at the Gastonia components and logistics facility, and 170 workers at the Western Star manufacturing facility in Portland.
