Sep 25, 2007 — General Motors workers in Massena are among the thousands nationwide who walked off the job this morning. United Auto Workers president Ron Gettelfinger says the union launched the strike after what he described as ``one-sided negotiations.'' The union is seeking more job security and better benefits. The picketing comes as General Motors prepares to close its Powertrain plant in Massena next year. David Sommerstein spoke with UAW local 465 president Tony Arquette Monday afternoon.
