Purpose: Notwithstanding the government's reform exertions in the security sector, performance remains below expectations, with criminal activity increasing on a daily basis. The factors contributing to this lousy performance have yet to be fully explored. The problem has a negative impact on the performance of security officers, who play an important role in insecurity issues. Because without security, economic development is a futile dream. To this end, the study aimed to examine the effect of working conditions on the performance of police officers in Marsabit County, Kenya.

Preliminary data collection required self-administered questionnaires for the target population. The researcher applied the test re-test technique to choose the reliability of the exam study. To establish the relationship between the variables, Pearson correlation analysis was performed on the dependent and independent variables at the 95% confidence interval. The data was prepared by distributing questionnaires to the assessed population. The collected data were analyzed qualitatively and quantitatively guided by the research topics and goals. Testing of quantitative information was performed using descriptive and inferential statistics and data presented in; tables, pie charts, graphs, tables and figures. When data is collected from open-ended questions, qualitative data is analyzed and presented according to themes.
 Findings: A conclusion was arrived that the subject under study was viable. Working conditions directly affected the performance of police officers from the study.
