More than 5,800 warehouse workers at the Bessemer, Ala., Amazon facility are voting this month on whether to join the Retail, Wholesale and Department Store Union. Supporters are protesting in solidarity with those workers.

The words “Solidarity with Bessemer” are painted on a car as demonstrators participate in a Tax Amazon car caravan and bike brigade to defend a payroll-based tax on big businesses, including Amazon, that the City Council passed last July in Seattle, Washington on February 20, 2021.
