The government found that more than 180 businesses have subjected non-Korean workers to assault, discrimination or wage delays.

The labor ministry announced on Wednesday that it had identified the perpetrators during two rounds of intensive labor inspection targeting 196 businesses in April and in September.

The ministry found that 182 businesses, or 93 percent of those inspected, were responsible for 846 violations, including physical assault, discriminatory treatment, delayed wages, extending working hours and the withholding of breaks and holidays.

The violators were subject to the ministry's correction order.

Following the ministry's instructions, 103 out of 123 businesses that had delayed wages completed payments totaling one-point-27 billion won.

A South Chungcheong-based company accused of assaulting a foreign worker and a Gangwon Province-based firm suspected of refusing to comply with the ministry's previous correction order regarding wage payment were transferred to prosecutors.
