The board should never be without four distinct individuals serving as the four officers: chair, vice-chair, treasurer, and secretary. If an officer resigns, someone should immediately be appointed on a temporary basis.
Make sure the vice-chair has substantial work.
Typically the board chair is over-extended and the vice-chair doesn’t have enough leadership responsibilities. Consider divvying up the liaison work with board committees—sharing this responsibility between the chair and vice-chair.
