Recent research indicates that career mobility under Chinese Communist rule has been shaped by state political screening and shifts in official ideology. Drawing on Weber's concept of modern bureaucracy and a study of schoolteachers in the Mao era , this article suggests that within the workplace official control of careers engendered an inferior and heterogeneous corps of management personnel, a deep schism between management and the staff, and a fractured division of labor. The antitheses of the rational features of modern bureaucracy, these arrangements fostered workplace friction and political resentment that precipitated post-Mao reforms. Primary evidence comes from recently declassified government documents and firsthand interviews with retired teachers.
