Seattle were laid off by Amazon after a unionization drive. The Washington Alliance of Technological Workers (WashTech) accused the company of violating union laws and claimed Amazon managers subjected them to intimidation and heavy propaganda. Amazon denied any link between the unionization effort and layoffs. Also in 2001, Amazon.co.uk hired a US management consultancy organization, The Burke Group, to assist in defeating a campaign by the Graphical, Paper and Media Union (GPMU, now part of Unite the Union) to achieve recognition in the Milton Keynes distribution depot. It was alleged that the company victimized or sacked four union members during the 2001 recognition drive and held a series of captive meetings with employees. An Amazon training video that was leaked in 2018 stated "We are not anti-union, but we are not neutral either. We do not believe unions are in the best interest of our customers or shareholders or most importantly, our associates." The video also encouraged to report "warning signs" of potential worker organization, which included workers using words like "living wage", employees "suddenly hanging out together" as well as workers showing "unusual interest in policies, benefits, employee lists, or other company information". In early 2020, Amazon internal documents were leaked, which said that Whole Foods was using a heat map to track which of its 510 stores had the highest levels of pro-union sentiment. Factors including racial diversity, proximity to other unions, poverty levels in the surrounding community and calls to the National Labor Relations Board were named as contributors to "unionization risk". Data collected in the heat map suggest that stores with low racial and ethnic diversity, especially those located in poor communities, are more likely to unionize. Amazon also had a job listing for an Intelligence Analyst, whose role it would be to identify and tackle threats to Amazon, which included unions and organised labour. On 4 December 2020, the National Labor Relations Board (NLRB) found that Amazon illegally fired two employees in retaliation for efforts to organize workers. In April 2021, after a majority of workers in Bessemer, Alabama voted against joining the Retail, Wholesale and Department Store Union, the union asked for a hearing with the NLRB to determine whether the company created "an atmosphere of confusion, coercion and/or fear of reprisals" ahead of the union vote. The vote had been met with "anti-union" signs and mandatory "union education meetings" according to Amazon worker
