One example from Brazil since that's the topic:
> Brazilian prosecutors have filed a lawsuit accusing electric carmaker BYD of human trafficking and keeping its workers in “slavery-like conditions” in its biggest market outside China.
> The investigation found the Chinese workers were brought to Brazil under false pretences and their visas did not match their jobs.
> Prosecutors said the workers were found working in “slavery-live conditions” and with "minimum comfort and hygiene”, calling them victims of international human trafficking
> The workers were forced to sleep on beds that did not have mattresses and as many as 30 people shared a bathroom, MPT alleged.
