How's this for bad campaign optics?

The United Auto Workers labor union is suing General Motors over the use of temporary workers at a plant in Indiana, saying that laid-off members from Lordstown could do the jobs.

The UAW filed the suit this week in federal court in Youngstown. The suit accuses the company of violating a labor agreement that allows laid-off employees with seniority to seek to relocate to other GM facilities.

The complaint says the union agreed to GM’s hiring of temporary employees in Fort Wayne, Indiana, through August 2018 to help with the launch of a new pickup truck.
