I have discussed the "five-year rule" several times before in this column — the revision of the Labor Contract Law (Rodo Keiyaku Ho) enacted in 2013. Under the amendment, any worker employed on serial fixed-term contracts (yūki koyō) for more than five years can give themselves permanent status. See my earlier stories for more details, particularly my March 2013 column, "Labor law reform raises rather than relieves workers' worries."
The amendment was supposed to give workers more job security. Or at least that is what lawmakers claimed the purpose was. From the start I had my doubts — doubts that are now being borne out.
The fact is, employers are using the amendment as an excuse to fire their workers or change their working conditions before April 2018. When the law was enacted, it was not grandfathered to entitle those who had already worked more than five years. That meant the clock started on April Fools' Day, 2013, and that the first time it will be possible to use this purported job-security measure will be April 1, 2018.
