Do all directors and staff have a copy of your non-profit's constitution and bylaws or at least know where they can find a copy?
The best practice is to read and know your bylaws and review both the constitution and bylaws annually. In addition, it's crucial that the board of directors read and know the non-profit's bylaws.
When directors and staff know the bylaws, the non-profit benefits from better continuity (i.e. if someone leaves suddenly) and accountability (i.e. directors and staff can identify when bylaws aren't being followed).
