LOUISVILLE, Miss. (WTVA) — The new Winston Plywood plant remains on track to begin production next spring. And while the company has hired a few specialty positions such as millwrights and electricians, its main employment push won’t come until February and March. That’s when it’ll hire more than 200 workers. Less than 30 people currently work for the company, according to David Morrell, vice president for community relations.  Morrell says machine testing probably will start in March and the first actual production will begin the first week of April. The plant, being built in the wake of last year’s devastating tornado, eventually will employ more than 300 people and represents an investment of more than $100 million on the site of an old Georgia Pacific plant.
