The study examined conflict management strategies and performance of non-teaching staff at the University of Maiduguri, Borno State-Nigeria, and 2019-2023. The specific objectives of the study were to determine the effect of accommodating conflict management strategy, and ascertain the effect of collaborating conflict management strategy on the performance of non-teaching staff at the University of Maiduguri. Two hypotheses were formulated and tested by the study. The study adopted the descriptive survey research design. The population of the study consists of 3369 non-teaching staff with a sample size of 374; this was determined using the Taro Yamane formula. The instrument of data collection was a structured questionnaire. The instrument was subjected to face and content validity. Cronbach alpha method was used to establish the internal consistency of the questionnaire items which yielded a reliability coefficient of 0.81. Data collected for the study were analyzed using descriptive statistics, precisely the mean (real limits of number) and standard deviation to answer the research questions while Chi-square statistic was used to test the hypotheses at a 0.05 level of significance. The findings of the study revealed that accommodating conflict management strategy has a positive significant effect on the performance of non-teaching staff (i.e. c2α = 812.23 > 21.03), and also collaborating conflict management strategy has a positive significant effect on the performance of non-teaching staff at the University of Maiduguri (i.e c2α = 712.212 > 21.03). The study concluded that conflict management strategies positively affect the performance of non-teaching staff at the University of Maiduguri. It was, therefore, recommended among others that the management of the University should consider the wishes of others in conflict, smoothing over or overlooking differences to maintain harmony at the University that will enhance the performance of non-teaching staff.
