[Excerpt] Most federal employees in the executive branch of government are not subject to a broad, overall prohibition on so-called “moonlighting.” Rank-and-file employees of the government are generally free to take an additional, compensated job outside of their federal work, subject to certain specific “conflict of interest” limitations. High-ranking officials of the government, on the other hand, may be prohibited from taking any outside compensated private job if they are presidential appointees, and may otherwise be limited in the type of outside employment and the amount of private compensation they may receive if they are non-career officials receiving compensation from the federal government over a particular amount. This report examines general statutory restrictions on certain types and categories of outside, compensated employment activities by federal employees, and surveys specific agency and departmental regulations prohibiting particular types and areas of outside, compensated employment activities for employees of that agency or department.
