New York union organizers gave marijuana to workers in order to get them to vote in favor of unionization, according to Amazon.
The objection was one of several made by the company Friday as it seeks to overturn a vote that created the first union in the company's history.
On April 1, the National Labor Relations Board said a majority of workers at the JFK8 warehouse in Staten Island, New York, had voted to join the Amazon Labor Union.
According to multiple reports, Amazon questioned the methods used by the ALU to win unionization votes. Insider couldn't get the filing.
According to reports of the filing, Amazon's lawyers said ALU organizers distributed cannabis to workers ahead of the vote, and that the NLRB cannot condone such a practice as a legitimate method of obtaining support for a labor organization.
New Yorkers over the age of 21 are allowed to use recreational marijuana.
A lawyer for the ALU told the AP that organizers handing out cannabis was no different than giving out free t-shirts.
Amazon and the ALU did not respond to Insider's requests for comment outside of normal working hours.
In an earlier filing, Amazon claimed that union organizers threatened immigrant workers with the loss of benefits and interfered with employees waiting in line to vote.
The vice president of membership of the ALU said on Saturday that Amazon's objections have no merit and that they should cease.
In a filing responding to Amazon's objections, the union laid out 21 of its own objections, which included claims of intimidation, and unlawful surveillance of workers.
The New York Times quoted Kelly Nantel, an Amazon spokeswoman, as saying that they believed the actions of the NLRB.
