Precision Castparts, a Portland manufacturer for the aerospace, medical, nuclear and other industries, had successfully defeated several attempts to organize their workforce over the last few years. The Machinists union decided to take a different tack, and carved out a small unit - re-work welders. They won the election 54-38, but the company, who appealed the original decision of the stand-alone unit and was rebuffed in September, is appealing again to the newly constituted NLRB, hoping for a different outcome.
