UAW strike against Detroit Big Three automakers could expand

The United Auto Workers' simultaneous but limited strike against Ford, General Motors and Stellantis could heat up on Friday, when the union plans to announce its next moves in the absence of new contract agreements with Detroit's Big Three.

UAW President Shawn Fain will deliver an update to members via a Facebook live message at 10:00 a.m. ET. He has threatened to expand the strike beyond the single assembly plants at each company at noon unless serious progress has been made in the negotiations.

There are a number of scenarios that could play out. One is that the union reaches a tentative agreement with each automaker, the strike ends and everyone goes back to work.
