Most professionals think hard about getting a job. Choosing the right outfit. Acing the interview. Negotiating a fair salary and benefits package. But rarely is much thought given to leaving a job until that day draws near. That can cause a wave of trouble for a not-for-profit organization, especially when the founder or long-time executive is ready to walk out the door one last time. Boards and executives who take a proactive approach to saying adiós can ease the transition to new leadership and help ensure stability in their organizations.
