But Amazon has recognised humans are the least efficient part of the operation, so in Tilbury the robots take over. At every turn it felt like the human staff were reduced to livestock, existing only to service the machines.
Alone in a locked metal cage, 10 feet from my nearest colleague, a robot approaches from the shadows and thrusts a tower of shelves towards me. I have nine seconds to grab and process an item to be sent for packing – a target of 300 items an hour, for hour after relentless hour. As I bend to the floor then reach high above my head to fulfil a never-ending stream of orders, my body screams at me. Welcome to Amazon's picking floor. Here, while cameras watch my every move, a screen in front of me offers constant reminders of my “units per hour” and exactly how long each has taken.
There were complaints of filthy toilets and breaks still too short. One asked: “Why are we not allowed to sit when it is quiet and not busy? We are human beings, not slaves and animals.”
