Abstract:
A number of studies have been conducted regarding the relationship between 
organizational citizenship behaviour and the Big-Five personality traits and have 
established some correlation between the variables.  The present study sort to 
assess the uncertainties between organizational citizenship behaviour and the 
Big-Five personality traits, using the perspectives of Chiaburu et al. (2011) and 
Ilies et al. (2009) among teachers in Greater Accra. In this regard, two secondary 
schools – Nungua and Osu Presbyterian Senior High Schools were used for the 
study. The study posited that there is a positive and significant relationship 
between the variables. Specific hypotheses concerning the relationship between 
the variables were tested using quantitative approach and descriptive research 
design. Questionnaires were used for data collection from selected institutions 
with a sample size of 120 teachers. The study found that openness to experience 
was the only personality trait that positively and significantly predicts all three 
dimensions of organizational citizenship behaviour. Again, openness to 
experience predicted the three dimensions of organizational citizenship 
behaviour more than the four other Big Five personality traits. Also, 
conscientiousness was found to positively and significantly predict OCB-I and 
OCB-CH dimensions. The hypothesized significant relationship between 
agreeableness, extraversion, neuroticism and the three dimensions of 
organizational citizenship behaviour was not supported. In view of the findings 
of the present study, it is recommended that institutions should recruit teachers 
who possess openness to experience and conscientiousness traits in order to 
improve teachers’ engagement in organizational citizenship behaviour.
