A lot of research both home and abroad have been carried out to ascertain variables that have its impact on employees’ performance. While emphases have been placed on monetary rewards; bonuses, incentives, increased salaries and wages and other cash rewards, other non-monetary factors like the serenity of work environment are seen as immaterial or irrelevant when compared with monetary rewards. Motivated by the need to ascertain non-monetary factors that might have an effect on employees’ performance in public sector, this study is aimed to test a model based on three dimensions of the work environment (physical work environment, training and development and cordial working relationship) on employee performance. The study adopted a quantitative research design and data were collected using structured questionnaire. The staff strength of the college is 520 employees consisting of both academic and non-academic staff. The study used both Pearson Product Moment Correlation Analyses and Multiple Regression Analyses using SPSS 21.0 and EViews 9.0. The correlation revealed that there is a strong relationship between the three dimensions of the work environment and employees’ performance. The multiple regression result showed that physical work environment and cordial working relationship have significant effects on employee performance while training and development was insignificant in predicting employee performance. This study recommends management continuous improvement of work environment dimensions because they influence employee performance.
