This is not the first time Seo Agency has faced criticism for its treatment of female employees.
In September, the agency was slammed after it emerged it was using a number of women to promote a film, despite having no representation of women in the company.
In August, the same agency was accused of discriminating against black female directors, as well as being in a state of neglect after it was revealed that only 13 of the 100 female employees it hired had worked at the agency for over a decade.
