Amazon warehouse workers from the company's Bessemer, Alabama site will soon vote on whether or not they want to join the Retail, Wholesale and Department Store Union, NPR reports. The vote will take place by mail due to concerns around COVID-19, the National Labor Relations Board decided, and will run from February 8 to March 29.

The scheduled vote follows a hearing where Amazon and the retail workers union decided who in the company should be eligible to have a say in the unionization effort. Both parties unanimously agreed that the company's many seasonal workers should also be able to vote.

Unions are common within Amazon's European operations, but no unionization efforts in the US have yet succeeded. The company is known for its aggressively anti-union stance, and earlier this year was called out for posting two job listings that described union-busting roles.
