Amazon workers at the warehouse in Bessemer voted to reject unionization by a more than 2-1 margin as of Friday morning, with a majority of the 3,215 ballots counted. More than 1,400 voted against forming a union, with some 600 ballots in favor.
In the latter case, the dispute would play out before the National Labor Relations Board (NLRB) and then likely in a federal appeals court.
The elections had voter turnout of about 55% the Retail, Wholesale and Department Store Union (RWDSU) said in a statement on Wednesday.
More than 3,200 mail ballots were received by the US National Labor Relations Board (NLRB), in an election open to over 5,800 workers at Amazon's warehouse in Bessemer, Alabama, the union said.
Trade unions estimate Amazon's delivery systems rely on 40,000 workers, including staff of its logistics arm, which employs most of Amazon's 9,500 long-term Italian staff.
This has prompted unions to seek tighter rules on workloads and shifts for drivers who they say deliver as many as 180-200 parcels a day.
Amazon is locked in a dispute with Future, which it says allegedly violated certain contracts by selling its retail assets to market leader Reliance Industries last year. Future denies any wrongdoing.
Justice J.R. Midha also said Biyani and other respondents cannot dispose their assets. "The assets ... are hereby attached," the order said.
Amazon has for several years been under investigation by the agency for possible violation of foreign investment rules. Such probes typically take years in India, and in most cases details are not made public.
On Friday, the senior Enforcement Directorate source told Reuters "obviously we have sought information" from Amazon.
Amazon, locked in protracted legal disputes with Future, alleges the Indian firm violated contracts by agreeing to sell its retail assets to rival Reliance Industries last year. Future denies any wrongdoing.
Indian stock exchanges last month cleared Future's deal with Reliance, despite Amazon's repeated requests to regulators to block the deal.
The move came a day after Reuters reported that Amazon had offered to help with the United States' efforts involving the COVID-19 vaccine, citing a letter addressed to President Joe Biden.
