How the UAW strike could have ripple effects across the economy

United Auto Workers members attend a solidarity rally in Detroit at the start of the union's strike against Ford, General Motors and Stellantis on Sept. 15. The union is striking against all three automakers at once for the first time ever, but only at targeted plants for now, making it even harder to assess what the strike's economic effects will be.

The United Auto Workers’ strike against the Big Three automakers will have ripple effects across the economy — but it’s hard to gauge how much.

It will depend in large part on how big the strike gets and how long it goes on. And what makes this walkout unusual is that the union is targeting all Big Three carmakers — Ford, General Motors and Stellantis (Chrysler’s parent company) — but it’s not picketing all of their plants, at least for now.

Initially, the strike is limited to just three assembly plants — one for each company — with a total of about 13,000 workers.
