Shanghai issued a labor security supervision regulation at a standard government press conference on November 29, which will be effective on January 1, next year.
To protect workers' legal rights, the city established labor security supervision institutions in 1998. By last month, these institutions had received more than 130,000 complaints, examined more than 210,000 employers and punished 77,000-plus illegal companies, which helped more than 2.7 million workers get back 2.7 billion yuan (US$340 million) in delayed salaries and compensation.
According to the new regulation, employers are under the supervision of the district or county-level labor security authorities of where their companies are located. When there are disputes between employers and workers in terms of salaries or other labor security affairs, employers are responsible for evidence. Employers of overdue payments will be punished. The labor security supervision department has the right to investigate, and those who prevent them from investigating will also be punished, said Jiao Yang, Shanghai government spokeswoman.
