RAYMOND, Wash. - Weyerhaeuser told the state Employment Security Department Wednesday that it is laying off about one-third of its remaining workforce at its mills in Raymond effective Monday.

The 50 affected workers will receive pay and benefits until May 7.

With the national housing market in the doldrums and salvage logging winding down in local forests after the destructive storms in December 2007, the Raymond sawmill is going from an 80-hour workweek to 60 hours. The planing mill will go from 60 hours to 40 hours. Before this layoff, the mills employed 141 hourly employees and 16 salaried employees.

Weyerhaeuser's Raymond and Warrenton mills have been shut down for one-week periods in each of the past several months because of low demand for lumber. Some workers have been sent home for longer periods.

The main Raymond mill produces dimensional construction lumber, which the company calls residential wood products - boards like 2x4s, 2x8s and 2x6s

In January, Weyerhaeuser shut down its two Aberdeen mills, putting 221 people out of work.
