Some said they had been punished when they reported the harassment, by being sent to a new work location or by being forced out of their company altogether -- but most respondents chose not to take action, instead ignoring the issue. Many also chose to quit, afraid that reporting the abuse would hurt their future job prospects.

Women and part-time or gig workers were more likely to be victims, while supervisors and managers were the most common perpetrators, the report said.

Many survey respondents said their mental health had deteriorated due to the abuse, though only a few sought treatment or counseling after developing depression, insomnia, lack of motivation and other issues.

Gapjil, a Korean word for those in power who lord over their subordinates, has long been a prevalent problem in the country -- especially within elite families who dominate South Korea's business and politics.

During his tenure, the former South Korean President Moon Jae-in, who left office in May, had repeatedly promised to tackle gapjil, which he described as a "leading workplace evil."

And it's not just bullying that is a problem in Korean workplaces -- gender discrimination remains deep-rooted too, especially during job interviews, when women are frequently asked about their plans for marriage or children.

Reports of office harassment decreased after the law, and even more so during the pandemic when employees largely worked from home, according to the Sunday report. But reports shot back up in recent months as people headed back into the office.
