In each staff meeting, I invite staff members to share their ministry victories and train them to always include a thank-you to another person on the staff who empowered this victory in some way.
Our staff is very task-oriented, and we find that doing some recreation together is essential. At staff retreats, we provide free group time to attend movies, play golf, or go sightseeing. But this each activity has to be done in groups of least three.
At least twice a year, it is important to us to have staff members participate in another staff member's ministry, either as a volunteer or an assistant. Seeing what others do alleviates self-pity and martyrdom, which are major causes of staff divisions. What you are up on, you are rarely down on.1
