0755 12333 is the special number of the national labor security telephone consultation service. It mainly provides public services such as policy consultation, information inquiry, service guide, complaints and reports in the fields of employment, social insurance, personnel, talents, wage income distribution and labor relations. With the increasing number of 12333 hotline calls, it reaches more than 10000 every day. However, due to the limitation of venue and staffing, the number of telephone consultations on the 12333 hotline can only reach about 2,000, which cannot meet the people's demand for human social security information consultation. The hotline 12333 was upgraded in an all-round way, and the number of consultants increased fivefold to 240.
