The National Labor Relations Board (NLRB) announced on Tuesday that it has found merit in charges against Amazon for violating labor law. The charges stem from Amazon’s refusal to bargain with a newly formed union representing employees at one of its New York warehouses.

In an order issued by the NLRB’s Brooklyn office, the agency stated that it is seeking remedies, including compelling Amazon to “bargain in good faith” with the Amazon Labor Union (ALU) and compensating the affected employees for the lost opportunity to negotiate as provided by national labor law.

Last April, workers at the JFK8 warehouse in Staten Island voted to join the ALU, a grassroots organization created by current and former employees. The ALU has been striving to secure a contract with Amazon ever since. However, the battle has extended into the courts, with the company challenging the election results and the conduct of the NLRB and the union. The NLRB upheld the election results in January.

The ALU has repeatedly urged Amazon to initiate contract talks, but the company has consistently refused, aiming to test the certification of the union as the exclusive collective-bargaining representative of its employees, according to the NLRB’s order.

Amazon representatives have not yet responded to requests for comment.

The NLRB’s complaint comes at a time when the ALU has faced setbacks following its significant victory in Staten Island. The union lost two elections at other Amazon warehouses last year, leading to divisions among some leaders and members. On Monday, a group of former ALU members filed a lawsuit against the union, accusing it of violating the ALU’s constitution. They have asked a Brooklyn court to compel the union to hold an election for union officers. The ALU’s lawyers have dismissed the lawsuit as baseless and untrue, as reported by The New York Times.
