AMAZON workers began voting on whether GMB should be recognised as their union today, after staging more than 30 days of strikes during nearly two years of fighting the retail giant’s union-busting tactics.

More than 3,000 staff will take part in the historic month-long ballot, whose outcome will be legally binding.

Officials from the union visited the company’s Coventry site today after the GMB was granted the right to hold the ballot by the independent Central Arbitration Committee.
