You are required to report in writing to your security office any planned or actual outside employment or activity that could create a real or apparent conflict with your responsibility to protect classified information from unauthorized disclosure.1 This includes any service whether volunteer, compensated, or employment with:
A leadership role in a professional, commercial, scholarly, or advocacy organization should be reported if the organizations activity is in a subject area related to your classified activities. The security office will generally approve any activity that can be shown to pose no conflict with your security responsibilities.
If an individual becomes disgruntled with his or her classified work and wants to develop the outside activity into an alternative career, there may be a strong temptation to deliberately reveal classified information.

The Morison case lead to Outside Activities being included as one of what is now 13 criteria used to adjudicate security clearances.
