Amazon warehouse workers in Alabama will have another opportunity to vote on whether to unionize after a federal agency determined that the company violated labor law in the previous election.

A National Labor Relations Board regional director gave Amazon workers the green light to hold another election, according to the Retail, Wholesale and Department Store Union.

AMAZON ACCUSED OF COMPROMISING UNION EFFORTS, WORKERS EXPLORE NEW VOTE

“Today’s decision confirms what we were saying all along — that Amazon’s intimidation and interference prevented workers from having a fair say in whether they wanted a union in their workplace — and as the Regional Director has indicated, that is both unacceptable and illegal,” Stuart Appelbaum, president of RWDSU said in a statement.

In a statement to the Washington Examiner, Kelly Nantel, an Amazon spokeswoman, said that its workers have always had the opportunity to unionize. She also said the company does not believe unionization is the right choice.

"Every day we empower people to find ways to improve their jobs, and when they do that, we want to make those changes — quickly," she said. "That type of continuous improvement is harder to do quickly and nimbly with unions in the middle. The benefits of direct relationships between managers and employees can’t be overstated."

In August, an NLRB official ruled that Amazon had wrongly distributed "vote no" materials to its workers and criticized the decision to have the U.S. Postal Service install a generic mail collection box near visible security cameras.

Amazon denied any wrongdoing and said that the workers voted "overwhelmingly" against unionization. The election was held in April. Much of it was conducted via mail-in ballot, with just 12.5% of eligible voters supporting unionization.

Leading up to the union vote, the company began aggressively pushing back against public criticism. At one point, it denied stories about its drivers having to pee in water bottles because of tight scheduling before admitting it was true.

Since then, the company has been releasing advertisements highlighting its working conditions.
