Many organizations are challenged with different issues arising from both the internal and external environments of the business. Despite these challenges, businesses need to remain competitive by identifying and managing such challenges effectively. Various works in the literature emphasize the importance of organizations successfully managing such changes. However, there exist some knowledge gaps as a result of many challenges that come with the process of change in an organization, leading to many organizations’ failure in successfully implementing change. The objective of the research is to evaluate the effects of integrating ethical principles in organizational change on employees’ performance through a survey of the Abuja Electricity Distribution Company (AEDC) in Nigeria. AEDC has approximately 3,378 employed staff. Using a mixed-method exploratory sequential approach, a qualitative research phase was conducted to explore participants’ views. Ten participants were randomly selected to provide a complex textual description of employees’ experience. Data were collected using focus group interviews and were analyzed using thematic analysis. Through the use of themes and coding, data were converted, transformed, and processed. Data generated from the first phase were used to develop an instrument that best fits the subject. The quantitative data were collected through an online survey questionnaire using Google Forms and were further analyzed using SPSS package. 345 participants’ responses were gathered for the quantitative sample using Krejcie and Morgan’s formula. The independent variables are the change processes identified by Lewin Kurt and John Kotter, and ethical principles while the dependent variables are the employees’ performance identified. The study concluded that integrating the principles of ethics is a potential solution for managing change effectively and reducing employees’ resistance. Important factors, including increased communication, stakeholder engagement that can impact customer satisfaction, and an enhanced relationship with customers, have been identified. Electricity utilities can improve their performance through ethical principles integration. The improvements can contribute to general employee performance and economic growth within a nation.
