Identity, Calling, and Workplace Spirituality integrates theological scholarship on the construct of work and calling with organizational psychology research on workplace spirituality and career fit. Frederick and Dunbar integrate these two domains to advance theological scholarship on vocation, work, and human nature. This focus provides crucial insights in terms of understanding how a Christian's work fulfills a God-given calling and reflects the Christian doctrine of the image of God.

In A Christian Approach to Work and Family Burnout, Thomas V. Frederick and Scott E. Dunbar provide a Christian spiritual model to prevent and cope with burnout caused by the workplace and conflict with family. Coupled with indifference and lack of urgency, burnout eliminates a sense of purposefulness and results in psychological depletion. To counter this, Frederick and Dunbar stress the importance of connecting with God in order to understand intrinsic motivations and redefine work as a calling and means to care for others.
