(Reuters) -An upstart union in North Carolina alleged Amazon ( AMZN ) interfered with the vote counting process on Saturday at a warehouse near Raleigh.

The union, Carolina Amazonians United for Solidarity and Empowerment (CAUSE), said it could not display a livestream of votes on its website because the retailer made three workers leave who were going to report results.

CAUSE alleged Amazon ( AMZN ) is "flagrantly violating labor law" and that the National Labor Relations Board, which oversees union votes, had "no issue with live-streaming the tally."

An Amazon ( AMZN ) spokesperson said the company and CAUSE "both have the same number of representatives in the room participating in the legal process." She denied that Amazon ( AMZN ) is breaking the law.

The vote counting began at 12 p.m. ET (1700 GMT) in Garner, North Carolina, where some 4,300 employees work. They could collectively bargain with Amazon ( AMZN ) if a simple majority approves the union. Voting began Monday with results expected later on Saturday.

The NLRB itself has accused Amazon ( AMZN ) of improper interference in prior elections, including two votes at a warehouse in Bessemer, Alabama. The agency has ordered a third vote as a result of what it said was misconduct, including intimidation of workers.

Amazon ( AMZN ) has vigorously opposed prior union actions, arguing that workers are better served by seeking changes directly with the company. Despite a successful 2022 union drive at a warehouse in Staten Island, Amazon ( AMZN ) has yet to recognize the group or negotiate with organizers.

The company said voters last month at a Whole Foods location in Philadelphia were coerced in order to win the election.

Amazon ( AMZN ), meanwhile, is contesting the NLRB's very existence in a federal lawsuit.
