Governments and industries are alarmed by vital occupations which are experiencing "skill shortages" due to diminished numbers of new entrants into these occupations and increased numbers leaving (e.g., engineering, agriculture, teaching, nursing). These occupations are literally vital for societies' survival. Vocational psychology can and should inform research and development which contributes to these vital occupations' workforce sustainability. Compared to other disciplines (e.g., economics), vocational psychology's theories and corpus of research evidence, and its applied profession—career development—are relatively absent from efforts to boost efforts to attract people into and retain them in these occupations. This presentation will describe a program of interdisciplinary research which involves collaboration with researchers in the professions of nursing and teaching—literally vital professions suffering workforce shortages across the globe. The presentation will demonstrate how vocational psychology theory, research, and practice has been integrated with the curricula and pedagogical systems of the two professions, and how vocational psychology research has been (increasingly) accepted in their respective disciplinary literatures as bringing new insights to seemingly intractable problems.
