5月19日，上海市社保保险事业管理中心，大量维权的外来人员综和保险购买者被警察强行塞进大巴车抓走。2011年6月30日前，非上海户籍的打工者由于无法参加上海职工保险，只能购买外来人员综合保险。2025年，上海出台了综合保险转社会保险的政策，但十年综合保险只能折算两年工龄，因此引发综合保险购买者不满，已发起多次维权行动，要求按1:1转社保。公开资料显示显示，约有400万人在就业期间被缴纳了外来人员综合保险。
On May 19, at the Shanghai Social Insurance Administration Center, a large number of migrant workers enrolled in the city’s Comprehensive Insurance Scheme who were protesting were forcibly pushed onto buses and taken away by police.
Before June 30, 2011, non-Shanghai hukou workers were not allowed to participate in Shanghai’s standard employee social insurance system and could only enroll in the Comprehensive Insurance Scheme for migrant workers. In 2025, Shanghai introduced a policy allowing comprehensive insurance to be converted into standard social insurance. However, ten years of comprehensive insurance contributions can only be converted into two years of pension seniority, sparking strong dissatisfaction among participants. Since then, multiple protest actions have been launched demanding a 1:1 conversion into social insurance.
Public records show that around 4 million workers were enrolled in the migrant workers’ Comprehensive Insurance Scheme during their employment.
