According to the labor office, the company forced the manager to work in excess of statutory working hours on 117 occasions between March and September last year. It also neglected its responsibility to carry out annual medical examinations for employees.

As he was in a management position, even if only by name, the deceased manager merely received 10,000 yen monthly as managerial compensation, and no overtime wages were paid. He died in September 2008 at his home in Amagasaki, Hyogo Prefecture.
