Causing concern about human rights
"Hiring workers in one city were wages and compensation are low and then sending them to work in more expensive cities is common practice for big companies in China, according to labour activists, and along with excessive overtime, punishments and underage employment, is causing concern about human rights in the country."
I wasn't aware that there was a time (since I've been alive at least) where there wasn't concern about human rights in China, and for much more serious reasons than employment issues.
