It is a system in which a staffing agency leases workers to companies. Contract work is a system in which workers, independent of a company's administration, complete a specific work task ordered by the company. An increasing number of companies use temporary and contract workers at low wages as a disposable workforce without full labor rights.Staffing services had been prohibited since the end of World War II on the grounds that employers' responsibilities become very vague and that workers are put in an extremely vulnerable position. However, the Temporary Workers Law, which was enacted in 1986 due to pressure from business circles, softened the ban. Since then, this law has been repeatedly revised. In 2004, the adversely revised law totally removed the ban on the use of temporary workers in the manufacturing industry. Only the JCP has consistently opposed successive adverse revisions.
