Which document requires general managers to submit monthly reports to the Mayor regarding departmental work?

The document that requires general managers to submit monthly reports to the Mayor regarding departmental work is typically an Executive Directive. Executive Directives are issued by a Mayor or other executive leaders to provide specific instructions, policies, or guidelines that need to be followed within a local government. This can include mandates for reporting requirements, which would ensure that the Mayor stays informed about departmental activities, performance, and any issues that may arise.

In contrast, while the City Charter outlines the fundamental structure and authority of local government, including powers of elected officials like the Mayor, it does not usually specify the regular reporting requirements of departmental heads. The Administrative Code contains detailed regulations and policies governing the operation of city departments but may not explicitly detail the frequency of reporting to the Mayor. The Department budget manual focuses on budgetary and financial guidelines rather than operational reporting. CAO Rules pertain to rules related to the Chief Administrative Officer's responsibilities but may not directly impose reporting requirements on general managers.

Thus, an Executive Directive is specifically tailored to establish expectations for communication and reporting, making it the appropriate answer in this context.
