Shein

In 2021 Public Eye investigated working conditions at Shein supplier factories in Guangzhou, China. Shein sources from a network of hundreds of small suppliers and sub-contractors, where workers usually have no employment contract, and no social security contributions. Workers commonly work 75 hours per week with no overtime premium and only one day off per month. Safety deficiencies abound. These are all violations of Chinese law.

In 2021 Public Eye scrutinised Shein's complex corporate structure. They found a great deal of offshore entities to disguise ownership and avoid taxes, with several Shein companies based in tax havens. A multitude of brands make the group even less tangible, with many brands sold by or through Amazon.
