Participation is a social process, which is basically part of an exchange relationship. Thus, it is principally pluralist and ambiguous in its meaning. As a consequence, the reconciliation of voices needs innovative approaches to support balanced participation experiences. The ambivalent character of participation intends to provide a look at new initiatives in the various fields of workplace participation. Leading international scholars examine the role of institutional contexts for participation, the development of new forms of interest organisation as well as the relationship between organisational performance, participation practices and quality of working life. The contributions are not limited to taking stock of new experiences in the field of workplace participation, but also contribute to designing a new research agenda.
