The study examined the Effect of business ethics on Workers performance, with Dangote Flour Mill, Apapa, Lagos as the case study. The study sought to determine the extent to which Workers’ awareness of ethical standards, organizational adherence to ethical conduct, and the prevalence of unethical behavior influence overall Workers performance. A descriptive survey research design was adopted, and data were collected using a structured questionnaire administered to 150 Workers, selected through simple random sampling. Out of these, 120 questionnaires were completed and returned. The study employed frequency tables, percentages, and Chi-square (χ²) statistics for data analysis. The findings revealed that ethical conduct positively and significantly affects Workers performance. Workers who are aware of organizational ethical standards and operate in an ethically guided environment demonstrate higher productivity, motivation, and commitment. Conversely, unethical behavior was found to negatively affect performance and organizational growth. The study concludes that business ethics are a critical factor in promoting accountability, enhancing Workers performance, and sustaining organizational success. Based on the findings, the study recommends that organizations establish clear ethical standards, enforce ethical policies consistently, provide ethics training for Workers, and recognize or reward compliance with ethical practices. These measures are essential for fostering a culture of integrity and achieving long-term competitive advantages.
