Scholarly works have generally considered organizational citizenship behavior (OCB) as a kind of individual behavior that is discretionary. However, with the advent of "bei" phenomenon (e.g., involuntary donation and compulsory overtime) in organizations, a growing body of research suggests that compulsory OCB is still prevalent in workgroups. More importantly, such behaviors can hurt labor relations and threaten organizational harmony. However, empirical research exploring the related field is relatively limited. As such, in the present article, we will take Chinese employees’ compulsory OCB as the research object and explore its formation mechanisms. In particular, based on trait activation theory, coercive persuasion theory, and self-determination theory, we aim to construct a multi-level formation model of employees' compulsory OCB from the levels of employee, leader, and organization. In practice, the research project is conducive to local enterprises to build a good and harmonious labor relation. In theory, the research results may contribute new knowledge to the field of OCB and promote the study and application of OCB theory in China.
