Objective: This thesis aimed to examine the impact of individual characteristics on adaptation to an Activity-Based Working (ABW) environment in terms of workplace satisfaction, experience at work, and work engagement. This study explored the impact of age, gender, job level, and management on perceptions of the ABW office. Method: The setting is a typology with a desk-sharing, space-use policy and mix of open-plan and enclosed offices and meeting rooms. This study used secondary, self-report data from a pilot study located at a U.S.-based research and consulting organization. The longitudinal study assessed two time points – two months and one year. Results: Employee outcomes were very similar between rounds. Gender was insignificant in predicting employee outcomes. Age and job level predicted some factors of job satisfaction, work experience, and work engagement. Conclusions: Adaptation is relevant to change management policies, space-use protocols, and participatory design. Keywords: Activity-based working (ABW), adaptation, change management
