Employment practices that support work–life balance and wellbeing in workplace experiences are critical pathways to long‐term workforce effectiveness, or cultivating a “sustainable workforce.” In this chapter, we discuss the notion of a sustainable workforce and examine how it relates to work–life balance and wellbeing. We then identify three organizational strategies that can be employed by researchers and practitioners to improve these linkages: promoting sustainable careers, increasing workplace social support, and safeguarding against work intensification. Finally, we present a research agenda which centers on developing sustainable workforces in organizations and fostering long‐term social benefits.
