Phenomenological approaches to Management and Organization Studies offer a means to problematize 'appearances' in the field, allowing us to 'see' things in a different light and uncover what is hidden from our consideration by our theoretical or ideological assumptions. This handbook aims at showing the unexpected richness and diversity of phenomenological and post-phenomenological thinkers such as Husserl, Heidegger, Merleau-Ponty, Arendt, or Scheler, as well as others belonging to the French new phenomenology (Marion, Henry) or the German neo-phenomenology (Schmitz). It also details the contributions of thinkers like Bachelard, Deleuze, or Foucault whose inscription and departures from phenomenology are illuminated. In this process, phenomenologies are historically, critically, and openly discussed by leading scholars while highlighting the interweaving between phenomenologies and other streams such as process studies or critical perspectives. Beyond a theoretical description, the chapters also show how phenomenologies and post-phenomenologies can help management and organization scholars and students to understand a huge variety of contemporary phenomena such as distributed collective activity, artificial intelligence, digitalization of organizational processes, remote work, financial markets and financial instruments, entrepreneurial events, cinematographic organizing of social media, issues of place and emplacement, commons and communalization processes and questions of embodiment and disembodiment at work.
