AGE, OCCUPATIONAL STRAIN, AND WELL-BEING: A PERSON- ENVIRONMENT FIT PERSPECTIVE Hannes Zacher, Daniel C. Feldman and Heiko Schulz ABSTRACT We develop a conceptual model, based on person-environment fit theory, which explains how employee age affects occupational strain and well- being. We begin by explaining how age directly affects different dimen- sions of objective and subjective P-E fit. Next, we illustrate how age can moderate the relationship between objective P-E fit and subjective P-E fit. Third, we discuss how age can moderate the relationships between P-E fit, on one hand, and occupational strain and well-being on the other. Fourth, we explain how age can impact occupational strain and well- being directly independent of P-E fit. The chapter concludes with impli- cations for future research and practice.
