Which department does the grid worker belong to?

Community or street management department. The subordinate departments of grid staff vary according to their posts, some are under the control of civil affairs departments, and some are under the control of neighborhood offices and police stations. Under normal circumstances, full-time grid workers are appointed or recruited, assessed and used by their communities (villages), and their positions are determined by contract system. The subordinate departments of grid members may be different due to different regions and management systems, so grid members belong to the management of community or street management departments.
