Legal basis: Article 9 of the Law on the Prevention and Control of Infectious Diseases in People's Republic of China (PRC) has clear legal provisions on the blockade of specific areas, and different levels of blockade are also decided by different levels of government. It is very important to take temporary blockade measures to control the spread and development of the epidemic in the critical period of fighting the epidemic. If you can't go to work on time due to urban isolation, the work unit still has to pay remuneration during the isolation period and can't terminate the labor relationship with the workers. The provincial government may decide to block the epidemic areas of Class A infectious diseases within its administrative area, but it is up to the State Council to block the epidemic areas in large and medium-sized cities or across provinces, autonomous regions and municipalities directly under the Central Government, and to block trunk traffic or block the border because of blocking the epidemic areas. During the period of isolation, the government that implements isolation measures shall provide living security for the isolated personnel, and the unit where the isolated personnel work shall not stop paying their remuneration during the period of isolation. According to the provisions of the Labor Contract Law, a unit may not terminate the labor relationship with the blocked or isolated personnel on the grounds of being blocked or isolated in an epidemic area.
