The UAW doesn't have to strike at every automaker or factory to shut down most of the auto industry

• Members of the United Auto Workers could strike on Friday, September 15 at midnight.
• The latest news out of the union suggests all members might not strike at once. 
• If the UAW's approach is to target certain plants, automakers are still in trouble.

If members of the United Auto Workers union strike on Friday, as is looking likely, the impact on Ford, General Motors, and Jeep-maker Stellantis will be monumental — even if not every automaker or factory is targeted.
