Protesters in San Francisco joined Amazon workers around the country in staging demonstrations and strikes in opposition to the company’s relationship with the U.S. Immigration and Customs Enforcement (ICE).

Workers gathered on Amazon’s biggest sales event of the year - ‘Prime Day’ – to voice a range of grievances ranging from unsafe working conditions, low pay and the company’s lack of action on climate change. They demanded Amazon stop marketing and selling its facial recognition software, called Rekognition, to law enforcement agencies including ICE.

One protester said the group had tried to deliver a petition of 270,000 signatures to Amazon representatives but were denied entry.

“They closed the door in our faces. There were four security guards, just telling us to leave. There was no-one from Amazon who was letting us talk to them,” she said.

Demonstrators held up posters with slogans including: “A prime example of racism,” “No facial recognition tech for ICE,” and “close the camps.” An Amazon box with a drawing of a child imprisoned behind bars was could also be seen in the protest.
