New York, Sep 18 (IANS): United Auto Workers (UAW) union and the Big 3 auto companies were set to resume talks on Sunday, being seemingly no closer to reaching deals than they were when autoworkers went on strike on Friday.

The union has rejected an offer from US automaker Stellantis to increase workers' wages by 21 per cent, Shawn Fain, head of UAW said on Sunday.

"I don't really want to say we're closer," he said. "It's a shame that the companies didn't take our advice and get down to business from the beginning."

Rather than focusing on one company as it has in the past, UAW is striking at one plant for each automaker to start a strategy that preserves union cash while leaving plenty of room to expand.

Fain repeatedly cited the 40-per cent pay raises for the Big 3 CEOs over the past four years, which are in stark contrast with the 6-per cent raises autoworkers have received since their last contract in 2019.

CEO pay has ballooned for decades, while wages for ordinary workers have lagged. "It's definitely a no-go. We've made that very clear to the companies," Fain said in an interview.

As the days of the strike increase, so will its impact. In a statement on Saturday, Ford says 600 workers were laid off from their Michigan assembly plant because of a halt in production when their paint department was called to strike.

Facing the laid-off, Fain responded that these workers won't go without income and said this is only a tactic being used for the union to settle for less. He criticised the company's behavior, saying it sees the workers as bargaining chips.

The union had talks with Ford on Saturday. It was going back to the bargaining table on Sunday with General Motors and plans to talk with Stellantis on Monday, a spokesman said.

Shares of Australia's BlueScope Steel Ltd slipped to an over three-month low as the ongoing UAW strike in the United States weighs on the Australian steel-maker's North American business.

BlueScope Steel shares fell as much as 3.8 per cent, their lowest since June 2, and are on track to log a sixth straight session of losses.

US President Joe Biden said he supports the union. But his climate agenda could conflict with the walkout and the labor demands as it may well require less labor.

The union had reportedly been negotiating with all three automakers simultaneously, in a break from previous rounds of contract talks, for significantly higher pay and new benefits.

Particularly, the UAW called for protections for workers with traditional auto jobs as companies increasingly invest in EV production.

Analysts warned that the strike, though limited for the time being, may develop into a prolonged one and a menace to the US economy, as it could cut production by thousands, push up vehicle prices and aggravate supply chain disruptions.

If all 150,000 workers for the Big 3 auto companies strike for at least 10 days, it would cost the US economy roughly 5 billion dollars, a local economy group estimated.
