Opposition lawmakers walked out in protest as the Lower House on Friday passed a contentious bill to revise the worker dispatch law, ending a requirement that companies upgrade their temporary workers to fully fledged employees after a period of three years.

The bill to revise the worker dispatch law was approved by a majority in the Lower House, after it secured approval earlier in the day from the House of Representatives Committee on Health, Labor and Welfare. It now goes to the Upper House for deliberation, but is nevertheless expected to be enacted as law by the end of the current Diet session.

Opposition parties protest that the bill will only benefit businesses and do nothing for the job security of dispatched workers, who lack many of the guarantees and benefits enjoyed by regular staff.
