Public welfare posts refer to non-profit public welfare management and social welfare service posts invested by governments at all levels, supported by policies or raised by the society, with the main purpose of realizing public interests and resettling people with employment difficulties. According to the relevant provisions of the state, province and city, the public welfare post policy is enjoyed for 3 years.

In other words, after the expiration of three years, you will no longer enjoy the preferential policies for public welfare posts. However, after the expiration of three years, many employees have renewed their contracts with employers because they are already skilled workers, which is allowed by the policy.
