OUTSOURCED cleaners at an Amazon warehouse in Kent are set to become the first British workers at a site run by the US-owned online giant to win union recognition, the United Voices of the World (UVW) said today.

The union said the staff, employed by Worcestershire-based contractor Phosters to service the site in Dartford, have won a historic concession from bosses to negotiate a voluntary recognition deal after they began balloting for strikes over pay.

The groundbreaking development follows calls for Amazon to officially recognise the GMB union as its members continue their landmark industrial action in Coventry.
