Abstract
Aim This thesis aims to develop a deeper understanding of how employees acculturate post-acquisition, its impact on their organisational identity. Methodology This research encompasses a qualitative case study which was developed by following an interpretative, abductive approach that allowed us to work simultaneously with theory and our empirical material. Nineteen semi-structured interviews, conducted at our case company Oaklers Group, together with observations, built the foundation of this thesis. Literature review In our literature review, we are outlining previous research on acculturation as well as on the concept of organisational identity. Contributions This thesis contributes to the existing literature with a detailed description of the individual acculturation process of employees, its impact on organisational identity and the influence of communication on the acculturation process.
