Abstract

This study investigated the moderating role of psychological breach of contract and violation on the relationship between mental wellbeing and sense of humour among workers of T-Man Nigeria LTD, Enugu state. A total of one hundred and seven (107) participants (44; 41.1 % males and 63; 58.9% females) participated in the study. Participants were drawn using convenience sampling technique and were administered questionnaire during their break period. Three instruments were used in data collation namely; the Coping Humour Scale (CHS), Warwick-Edinburgh Mental Well-being Scale (AWEMWBS) and Psychological Contract Breach and Violation Scale (PCBVS). Two hypotheses were tested and the results showed that sense of humor significantly and positively correlated with psychological well-being at r=1.00, while psychological contract significantly moderated the relationship between sense of humor and psychological wellbeing (f-change= .000, p< .05). The findings indicate that the presence of sense of humour will always increase the levels of psychological well-being and existence of psychological contract breach will always influence the relationship between sense of humor and psychological well-being.
