About 1,200 Weyerhaeuser Co. employees in Washington and Oregon voted overwhelmingly Thursday to give the regional woodworkers union strike authority, paving the way for a work stoppage if negotiators continue to disagree on terms of a new labor contract.The final ballot tally was more than 90 percent in favor of strike authority, said Wayne Thompson, district business representative of the International Aerospace and Machinists/Woodworkers Local District W24 Lodge. …“I’ve never seen our crews this solid,” he said. …“We are disappointed in this outcome, but optimistic that we can continue to work with union leaders to reach a mutually acceptable agreement,” Weyerhaeuser said Friday in a statement.
