Street cleaners in some parts of China are reportedly being forced to wear GPS-tracking smartwatches so employers can monitor how hard they work,

According to a recent Xinhua News Agency report, it is mandatory for cleaners employed by the Nanjing West Bank Environmental Service to wear smartwatches while working, raising concerns about mass surveillance across the country.

The smartwatch is said to sound an alarm after 20 minutes of worker inactivity and also reports their activity back to the company's control room.
