The Globe and Mail reports in its Friday edition that a British union has filed a legal challenge against Amazon, accusing the U.S. e-commerce giant of inappropriately influencing warehouse workers to vote against unionization. A Reuters dispatch to The Globe says that on Wednesday, warehouse staff in Coventry, central England, rejected a vote to become the first site outside the U.S. to force Amazon to negotiate labour terms. The GMB union narrowly lost the ballot, with 49.5 per cent of the 2,600 workers who voted polling in favour, versus 50.5 per cent against. In a complaint to Britain's labour law regulator submitted on Wednesday, the GMB union said Amazon had inappropriately quizzed workers on whether they were pro-unionization, and placed posters around the site with QR codes that workers could use to cancel their union membership. If the Central Arbitration Committee (CAC), an independent body that adjudicates on collective bargaining rights, accepts GMB's complaint, the body could order that a fresh unionization vote take place at the Coventry site. Amazon says GMB's complaint has no merit, pointing out that the recognition ballot "was conducted by an independent third party organization appointed by the CAC."
