The strike by auto workers is entering its 4th day with no signs that a breakthrough is near

The auto workers' strike against Detroit's Big Three went into its fourth day with no signs of an early breakthrough and against the threat that the walkout could soon spread.

A spokesman for General Motors said that representatives of the company and the United Auto Workers were continuing to negotiate on Monday.

So far the strike is limited to about 13,000 workers at three factories — one each at GM, Ford and Stellantis. GM warned, however, that 2,000 UAW-represented workers at an assembly plant in Kansas City are “expected to be idled as soon as early this week" because of a shortage of supplies from a GM plant near St. Louis, where workers walked off the job Friday.

Workers at the Kansas City plant build the Chevrolet Malibu and Cadillac XT4.
