AMAZON employees are exposed to such gruelling working conditions, they fall asleep on their feet, it has been claimed.

Bone-weary workers reportedly have just nine seconds to process a package during the long-hours at the online store warehouse, with a Mirror investigation claiming employees are suffering panic attacks as they struggle to keep up with demand.

According to the news outlet, one worker even had to be taken to hospital by an ambulance when they collapsed on the job.

Others simply slumped asleep where they stood, exhausted from the physically demanding job that sees them walking at least 10 miles a day.

Amazon has insisted that it provides a "safe and positive workplace", but according to the Mirror, a whiteboard of staff comments was full to the brim of complaints.

One staff member asked bosses: "Why are we not allowed to sit when it is quiet and not busy? We are human beings, not slaves and animals."
