UAW Strike
For the first time since 2007, tens of thousands of U.S. workers at General Motors went on strike on September 16. The work stoppage ended on October 25 after costing the automaker several billions of dollars and postponing the start of production of the new 2020 Chevrolet Corvette to February.
And speaking of GM, we can't forget the closure of the Oshawa assembly plant in Ontario on December 18.
