Abstract: The paper intends to introduce the theory of calling to human resource management in public sector. By applying the mechanisms and theories of how career calling can benefit a worker's health, well-being, and work motivation, the paper proposes that the construction of civil servants' value system could be promoted by exhibition of how public people are benefited by the public service work; the evaluation effectiveness of the ethics of civil servants in selection could be improved by focusing on the measurement of their calling; the sustainable work motivation of civil servants could be facilitated by convincing them about long-term benefits of calling for individuals' physical, mental health and well-being.
