The study examined workers' personal factors and personality characteristics as predictors of Organizational Citizenship Behaviour (OCB). The study employed Ex-Post-Facto within-participants randomized group design. Data were collected from five hundred and four employees of private and public human service organizations in Nigeria. It was hypothesized that employees' demographic factors and personality characteristics would significantly predict Organizational Citizenship Behaviour. Logistic regression showed that personal factors were not significant predictors of (OCB). Results indicated that personality traits of extraversion and openness significantly predict workers' Organizational Citizenship Behaviour (OCB). The F-ratio associated with the R2 = 0.755 shows a significant joint prediction of OCB (p<0.05) indicating that a total of 75.5% of the variance in OCB can be accounted for by the combination of the personality variables, while about 25.5% of workers' OCB is accounted for by other variables other than personality or dispositional factors. Based on these results, greater OCB was observed in individuals who score high on extraversion and openness to experience. Personality factors were revealed as important predictors of OCB. The study identified some future directions for personality research in industrial, work, and organizational psychology and concludes with some caveats and directions for future research.
