More than 5,800 Amazon employees in Alabama are set to vote in a mail-in ballot; the first time attempt by US-based workers of the company to unionise.
Led by the Swedish organisations Folksam and Ohman Fonder, the investors own approximately $20bn (£14.5bn) in Amazon shares, and include the comptrollers of Legal and General Investment Management, BMO Global Asset Management and the Church of England Pensions Board.
In a letter, the group urged the retail giant to end its union-busting – which included posters and compulsory meetings during work hours – and return to neutrality, inferring Amazon was going against its own Global Human Rights Principles, which are listed on its website.
In a statement, Amazon said: “We have provided education that helps employees understand the facts of joining a union.
“If the union vote passes, it will impact everyone at the site and it’s important associates understand what that means for them and their day-to-day life working at Amazon.”
