If gross labour law violations are detected during the month-long crackdown, the ministry plans to send papers to prosecutors and publicise the names of the offending companies.
The crackdown is intended to help workers like the 26-year-old Tokyo man who joined an apparel trading company after graduating from university in the spring of 2011 and soon found himself in a hellish working environment. His boss yelled at him almost daily, and fists flew from time to time.
"If you don't reach your sales targets, don't take holidays," he was reportedly told. "You're just a waste of space."
The man was forced to work until late every night, and often came into the office on weekends. Although he clocked up more than 100 hours of overtime every month, he did not receive overtime pay. The company hired five new employees every year, but they would soon quit.
Eventually, the man could no longer stand the working environment. In autumn 2012, he resigned.
