IMPACT OF EMPLOYEE LANGUAGE DIVERSITY AND VALUE DIVERSITY ON ORGANISATIONAL PERFORMANCE IN ADAMAWA STATE UNIVERSITY, MUBI, NIGERIA

This study examined impact of employee language diversity and value diversity on organisational performance at Adamawa State University, Mubi, Nigeria. A cross-sectional survey approach was adopted, targeting a total workforce of 927 employees comprising 352 academic staff (38%) and 575 non-academic staff (62%). Based on Yamane’s sampling formula, 281 participants were selected and distributed proportionally across the two groups. Data were gathered through the use of structured, closed-ended questionnaires, administered directly by the researcher, with the convenience sampling technique employed. The questionnaire was designed on a five-point Likert scale, drawing some items from prior empirical studies. Analysis was conducted using SPSS version 20.0, applying descriptive statistics and regression analysis with a 5% significance threshold. The findings indicate that language diversity exerts a strong and significant positive effect on organisational performance (β = 0.493, t = 8.115, p = 0.000), implying that embracing multiple languages fosters better communication, teamwork, and productivity. Furthermore, value diversity demonstrated a significant positive relationship (β = 0.140, t = 2.068, p = 0.040), showing that a mix of cultural and personal values, when effectively managed, enhances innovation and decision-making. The study concludes that cultural diversity has a notable impact on organisational performance, especially through language and value dimensions. It recommends that university leadership should reinforce diversity policies by promoting multilingual initiatives and value-based inclusivity, while ensuring a respectful and tolerant environment for religious differences. Such efforts are vital for building an inclusive workforce that strengthens collaboration and institutional productivity.
