Workers at another Amazon warehouse in Tilbury, south east England, had walked out in August on an impromptu basis and without a formal ballot. The Coventry strike is the first legally mandated action against Amazon in Britain.
An Amazon spokesperson said the company already offers competitive pay and comprehensive benefits. When asked if they officially recognised the role of the union in pay talks, the spokesperson said: "Having a direct relationship with the company is best for our employees."
The Nasdaq-listed group has faced criticism from labour advocates in the United States for discouraging union membership among workers through mandatory staff meetings to warn staff about unions.
