The aim of this study was to identify the discrepancy between the perceived and desired organizational culture in a pharmaceutical company that underwent a process of acquisition and integration, as well as to examine the impact of these differences on employee motivation. The research was conducted using a case study approach, combining a quantitative survey based on Harrison’s typology with qualitative interviews and observational techniques. The sample included 224 respondents from various organizational units. The findings reveal a dominant orientation toward task culture, alongside the presence of bureaucratic and power-oriented cultural elements, while employees clearly express a preference for more flexible and team-based structures. These discrepancies point to the importance of cultural transformation in improving motivation and organizational efficiency. It is concluded that aligning the actual and desired culture constitutes a critical strategic challenge for management during post-integration phases.
