The UAW is about to cause yet another auto industry supplier to move jobs offshore, this time from Arlington-based Lear corporation. Not wanting to face business realities, the UAW has been attempting to get both state officials and GM management to put pressure on the parts supplier. Phil Wilson decried the tactic as an ineffective gambit. “At the end of the day, the UAW will have to create its own leverage with Lear — either at the bargaining table at unionized locations or by organizing nonunion locations,” said Wilson. “As far as GM’s public image is concerned, whether its suppliers work offshore will have little impact,” he added. “It is much more important that GM produces great cars that people want to buy.”
