A District government employee shall not engage in any outside employment or other activity incompatible with the full and proper discharge of his or her duties and responsibilities. Activities or actions that are not compatible with government employment include, but are not limited to the following:
A District government employee may receive compensation for engaging in teaching activities, writing for publication, consultative activities, and speaking engagements that are not prohibited by law, regulation, or agency standards, only if such activities are conducted outside of regular working hours, or while the employee is on annual leave, compensatory leave, exempt time off, or leave without pay.
The information used by an employee engaging in an activity under Subsection 1807.2 of this section shall not draw on official data or ideas which have not become part of the body of public information, except nonpublic information that has been made available on request for use in such capacity, or unless the agency head gives written authorization for use on the basis that its use is in the public interest.
If the employee receives compensation or anything of monetary value for engaging in an activity under Subsection 1807.2 of this section, the subject matter shall not be devoted substantially to the responsibilities, programs, or operations of his or her agency, to his or her official duties or responsibilities, or to information obtained from his or her government employment.
An employee who is employed for not more than one hundred thirty (130) days during any period of three hundred sixty-five (365) consecutive days, to perform temporary duties, either on a full-time or intermittent basis, shall be subject to Subsection 1807.1(h) of this section only in relation to a particular matter involving specific parties in which he or she has at any time participated personally and substantially as a District government employee, or which is pending before his or her employing agency.
Nothing in this section shall prevent an employee from acting without compensation as agent or attorney for another District employee who is the subject of any personnel action, if not inconsistent with his or her duties.
Nothing in this chapter shall prevent an employee from acting, with or without compensation, as agent or attorney for his or her parent(s), spouse, domestic partner, child, or any person for whom, or for any estate for which, he or she is serving as guardian, executor, administrator, trustee, or other personal fiduciary except in those matters in which he or she has participated personally and substantially as a government employee, through decision, approval, disapproval, recommendation, the rendering of advice, investigation, or otherwise, or which are the subject of the employee's official responsibility, provided that the government official responsible for appointment to the employee's position approves. This provision shall not abridge a government attorney's responsibilities under the District of Columbia Rules of Professional Conduct.
