Abstract  Title: Managerial Expectations on the Implementation of Reduced Work Hours: Evaluating Productivity, Leadership Adaptation, and Workplace Dynamics Author: Simon Bonnevier Supervisor: Michal T. Lysek  Background:  Over the past decade, organizations have experimented with Reduced Working Hours (RWH) while maintaining salaries to improve employee well-being without compromising performance. Although research suggests potential productivity gains and improved work-life balance, the leaders’ role in balancing flexibility with operational needs remains underexplored.  Purpose:  To explore how managers in the sports, construction, banking, travel, and automotive industries expect the implementation of RWH to affect productivity and leadership capabilities.   Method:  Outlines the qualitative, inductive study design with a subjectivist ontological perspective and a hermeneutic epistemology. Inspired by Classic Grounded Theory, an iterative process with theoretical sampling. Data were collected via semi-structured interviews, transcribed verbatim, and analyzed through open and selective coding with constant comparison and memo writing until theoretical saturation. Five leaders in various organizations have been interviewed through qualitative interviews.   Results and Discussion:  Presents the model for Reduced Work Hours (RWH), developed through coding the empirical data. The model is illustrated as a triangular structure with three integrated Level 3 codes—“Conflicting Accustomations,” “Leadership Process for RWH,” and “Organizational-Level Strategies”—that interact to enable a sustainable and engaging implementation of RWH. The results are compared and discussed with existing research and relevant theories.
