Failing to Understand Fiduciary Duties. When you volunteer to serve as a director or officer of a nonprofit, you accept the responsibility to act with the duties of good faith, due care and loyalty. You also accept the potential liability for failing to fulfill those duties. Increased scrutiny from the I.R.S., Congress, state attorneys general, the Department of Justice, donors and the media require vigilance at every step. It is no longer sufficient to rubber stamp committee or staff recommendations or to simply “abstain” from dicey decisions. Today, board service comes with real responsibilities and real consequences for those that fail to live up to them.
