(For those curious like me) ブラック企業

A black company (ブラック企業, burakku kigyō), also referred to in English as a black corporation or black business, is a Japanese term for an exploitative, sweatshop-type employment system.

While the term "sweatshop" is associated with manufacturing, and the garment trade in particular, in Japan black companies are not necessarily associated with the clothing industry, but more often with office work.

While specifics may vary from workplace to workplace and company to company, a typical practice at a black company is to hire a large number of young employees and then force them to work large amounts of overtime without overtime pay. Conditions are poor, and workers are subjected to verbal abuse and "power harassment" (bullying) by their superiors.[1] In order to make the employees stay, superiors of black companies would often threaten young employees with disrepute if they chose to quit.
