Amazon.com Inc. employees at a North Carolina warehouse filed a petition with the National Labor Relations Board requesting an election to determine if workers in the facility will be represented by a union.

Carolina Amazonians for Solidarity and Empowerment said in a statement Monday that it believes an organizing effort collected signatures representing at least 30% of the workforce at the site, which would force an election. An Amazon spokesperson wouldn't disclose the current number of employees at the facility, which opened in Garner, North Carolina, in 2020.
