Workers for some suppliers of Chinese fast fashion giant Shein are still working 75 hours a week, despite the company promising to improve conditions, a report suggests.

A new investigation by Swiss advocacy group Public Eye has followed up on its 2021 report, which found a number of staff across six sites in Guangzhou were doing excessive overtime.

According to the group, who interviewed 13 employees from six factories in China supplying Shein for its latest investigation, excessive overtime was still common for many workers.
