How Shawn Fain, an unlikely and outspoken president, led the UAW to strike

United Auto Workers President Shawn Fain has launched a series of targeted strikes at factories owned by GM , Ford and Stellantis .

The current UAW contract with the domestic car companies expired at midnight , and that's when workers at three plants walked off the job.

Fain often talks about his family members who began working in car plants in the earliest days of the UAW .

Shawn Fain ran on a platform to end corruption, to win back what the union had given up in concessions 15 years ago .

Fain won by the narrowest of margins, just 477 votes.

He held campaign events on Facebook Live where he'd take questions from members who logged in for hours at a time.
