C. Wright Mills on the coordination of bureaucratic work

“The rise of thousands of big and little bureaucracies and the elaborate specialization of the system as a whole create the need for many men and women to plan, co-ordinate, and administer new routines for others. In moving from smaller to larger and more elaborate units of economic activity, increased proportions of employees are drawn into co-ordinating and managing. Managerial and professional employees and office workers of varied sorts–floorwalkers, foremen, office managers–are needed; people to whom subordinates report, and who in turn report to superiors, are links in chains of power and obedience, co-ordinating and supervising other occupational experiences, functions and skills”
