Garfield Hylton has long known that Amazon monitors and logs every minute of his working day. Every product he scans, every second he takes between scans, every time his scanner is briefly inactive – all of it is tracked, recorded, and used to set productivity targets and predictions.

But what 62-year-old Hylton didn’t know is that Amazon seemingly also monitors potential “dissent” in the Coventry warehouse where he works, using AI to surveil posts on social media and the company’s internal staff bulletin board.

Internal documents made public as part of a court battle between Amazon and a Canadian union suggest the tech giant uses Atlas, an in-house AI forecasting tool, to predict how likely its warehouse staff in the US, Canada and the UK are to attempt to form a union, stage a sit-in, or conduct other “disruptive labour events”.
