In the long-running struggle between union-minded American workers and employers, President Biden is in the workers’ corner.

And he obviously has one major employer in mind: Amazon.

“I made it clear during my campaign that my policy would be to support unions organizing and the right to collectively bargain,” Biden said in a video statement on Twitter Sunday night. “I’m keeping that promise.”

Workers in Alabama – and all across America – are voting on whether to organize a union in their workplace. It’s a vitally important choice – one that should be made without intimidation or threats by employers.

Although he did not name Amazon, the president did reference warehouse workers in Bessemer AL, where the on-line retailing giant has been fighting to remain free of organized labor.

“More than 5,800 warehouse workers at the facility are voting this month whether to join the Retail, Wholesale and Department Store Union, [RWDSU],” reports NPR, adding that: “The mail-in ballot election runs through March 29 and could be the first Amazon warehouse union in the United States.

“If successful, it would also be a major victory for labor organizing in the South, a region difficult for union success.”

“It’s rare for a sitting president to publicly support a union drive, and [Biden’s]  statement is careful not to direct workers to vote in favor of unionization, as such statements might violate labor law,” says tech news website The Verge, noting that the president “denounces anti-union efforts in a way many will see as aimed” at Amazon.

“There should be no intimidation,” Biden says in the video, “no coercion, no threats, no anti-union propaganda.”

One Twitter post called it “the strongest pro-union statement by a president since FDR.”

In what many say is the strongest pro-union statement by a president since FDR, Biden praised the many benefits of unions and, clearly referring to Amazon's fierce anti-union campaign in Alabama, said employers shouldn't interfere in unionization drives.https://t.co/RDFqYOP1K4

“Although many of Amazon’s European warehouse workers are union members, the e-commerce giant has successfully fended off organized labor at its U.S. facilities throughout its 27-year life,” reports the Washington Post.

“Amazon has actively worked to discourage its Bessemer employees from supporting the union, calling them into mandatory meetings to disparage the union, peppering them with texts urging ‘no’ votes and even placing fliers on the inside of bathroom stalls at the warehouse, decrying the collection of union dues,” the Post says.

It’s worth nothing that the Post’s owner, Jeff Bezos, founded Amazon and has long served as its CEO, although he’ll be leaving that position later this year. Bezos has been touted as the world’s richest person, with a net worth topping $200 billion.

“A group of 50 Congresspeople sent a letter last month urging [Bezos] to ‘treat your employees as the critical asset they are, not as a threat to be neutralized or a cost to be minimized,’” notes CNN.

Dozens of unions and other labor groups and activists have urged Biden to back workers against Amazon, and several made it clear on Monday they’re gratified by his words of support.

“We haven’t had this aggressive and positive of a statement from a president of the United States on behalf of workers in decades,” said Faiz Shakir, a former senior aide to Sen. Bernie Sanders (I-VT) and founder of the pro-labor group More Perfect Union.

“It means a lot.”
