quality is offered as a solution to challenges such as health, welfare, productivity, innovation, economic competitiveness, democracy and democratic participation, Bildung/cultivation, societal equality, individual and collective quality of life, and environmental sustainability. As job quality is a key factor in addressing these and the other challenges, it needs to be understood in all its complexity in terms of what it affects as well as what affects it. This Handbook draws together into a
single volume: first, an explicit focus on job quality both as a significant factor in and of itself and as producing instrumental effects on a range of other processes and outcomes; second, a catalogue of the diverse range of multiple contributions and applications related to job quality; and third,
the complexity and multiple interpretations of the concept of job quality. Each chapter provides distinct responses to the question of why job quality matters, coupled to a contention about for whom or for what job quality matters most. As the chapters with their respective answers and arguments attest, there are a range of ways in which job quality is relevant to an equally broad range of social, economic, and political concerns.
