AMAZON workers walked out on Black Friday today in their long-running dispute over pay.

GMB union members at the online giant’s site in Coventry mounted an early morning picket outside the centre, on one of the busiest shopping days of the year.

Strikes and demonstrations are also being held in other European countries and the US, which unions say will be the biggest day of action in Amazon’s history, and a protest is due outside the company’s London offices.
