While FinTech is a relatively recent subject in academic literature, it is widely acknowledged as one of the most notable innovations within the financial industry. Despite the growing interest in FinTech, there is currently a lack of comprehensive understanding regarding the exact implications it will have on established financial institutions. The introduction of FinTech solutions has brought about a significant transformation in the banking industry of Finland. Nevertheless, the influence of FinTech adoption on employee’s satisfaction and performance in banks remains uncertain. This has emphasized the need for a deeper understanding of the opportunities and challenges presented by this form of technological innovation across all aspects of the financial industry. The purpose of this research is to bridge the existing gap in literature by examining the relatively unexplored area of how the adoption of FinTech solutions influences job satisfaction and performance among employees in the context of a Finnish bank. Specifically, this research centered on OP Bank, which is recognized as one of the largest banks in Finland. By conducting an in-depth exploration of the experiences of employees at OP Bank, this research will offer valuable insights into how the adoption of FinTech solutions influences employee’s behavior in the Finnish banking industry. To accomplish this, the study utilizes a qualitative exploratory research approach, employing semi-structured interviews as the data collection method, involving 8 middle-level employees from OP Bank. This methodology facilitates a deeper understanding of employees' experiences and perspectives, thereby generating rich and detailed data. The findings of our research reveal several key conclusions regarding the varying ways that the adoption of FinTech solutions influences employee’s job satisfaction and performance. The insights gained highlight the crucial role of FinTech in transforming traditional banking practices, driving innovation, and fostering a positive work environment for employees in the financial industry. Understanding the complexities linked to FinTech adoption is imperative for banks and financial institutions to effectively leverage the complete potential of these technological innovations, thereby steering employee’s satisfaction and performance in the desired direction. Through an in-depth examination of this phenomenon, we have gained a better understanding of the benefits and challenges associated with FinTech adoption, as well as its influence on employee’s job satisfaction and performance. Moreover, this study has provided crucial insights for improving employee’s satisfaction and performance in banks that have embraced FinTech solutions, thereby contributing to a deeper understanding of successful FinTech adoption in the Finnish financial industry. Additionally, this research has contributed to the existing literature on FinTech, management of employee’s satisfaction and performance, employee behavior and technology adoption. These findings have offered practical theoretical, managerial and societal contributions.
