Slave-driving online retailer Amazon was handed a 55,000-name petition yesterday demanding better treatment for its underpaid and exploited workers.

Forty members of campaign group Amazon Anonymous delivered the petition to the anti-union tax-dodger's central London offices in one of its own cardboard boxes.

"Since starting the petition in December and seeing the overwhelming feeling against Amazon, I've been collecting stories from real Amazon workers and ex-workers about their warehouse experiences," said Amazon Anonymous leader Emily Kenway said.
