Work gets done. Time passes. Careers— sequences of work experiences over time—unfold. A career depicts the person, the elementary unit in work arrangements. Careers invoke relationships within and among firms. Careers spell economic and social outcomes. Put simply, everyone who works has a career. And everyone’s life outside work is connected to the career. As lives are lived, a focus on careers, rather than on jobs, insists that we account for time and its implications. Careers matter!
