Providing an overview of researchers' and practitioners’ “confessions” on the fascinating phenomenon of failed or derailed organizational health and well-being interventions and contextualizing these confessions is the aim of this innovative volume. Organizational intervention failures, paradoxes and unexpected consequences can offer a lot of rich and extremely useful practical lessons on intervention design and implementation and possibly on the design of future research on organizational interventions. This volume presents lessons learned from derailed interventions and provides possible solutions to those tasked with implementing interventions. It provides an open, practical and solutions-focused account of researchers' and practitioners' experiences in implementing organizational interventions for health and well-being.
