Simpson Timber Co. announced recently that it will lay off workers at its Tacoma and Shelton sawmills. The Tacoma Tideflats sawmill will lose 46 of its 144 employees, and the Shelton mill will lose 65 of its 294 employees. Housing starts are down significantly since 2005. The mills make dimension lumber, such as two-by-fours used primarily in residential construction and remodeling. Simpson will work to provide all affected workers with information regarding state unemployment services and benefits for which they are eligible, according to a company news release.
