PurposeThis study aims to examine emotional intelligence (EI) and organizational communication as predictors of teamwork effectiveness among bank employees in Nigeria. The Nigerian banking industry suffered financial crisis, leading to depression, following inability to meet standards of the regulatory body. With current emphasis on teamwork for business growth, literatures suggest EI and organizational communication as predictors for teamwork effectiveness.Design/methodology/approachA cross-sectional survey of 230 bank employees, selected through multistage sampling, using a valid and reliable structured questionnaire that incorporated all research variables was used for data collection. A questionnaire containing the research scales was administered and data were collected.FindingsPositive relationship was established between perceived teamwork effectiveness and components of EI, including self-emotion appraisal, other’s emotion appraisal (OEA), actual use of emotion and regulation of emotion (ROE) and perceived organizational communication effectiveness. Hierarchical regression analysis reveals that age, gender, job status and educational qualification jointly predicted teamwork effectiveness, although only educational qualification contributed significantly. The inclusion of EI dimensions showed that only OEA, actual use of emotion and ROE were significant predictors, along with organizational communication.Research limitations/implicationsData collected were based on self-report of the participants. It is advised that more objective measures could be devised. The findings are limited to the banking industry and cannot be generalized to other work organizations. The research was conducted in Nigeria, a developing country; thus, the findings may not be generalized to the developed nations.Practical implicationsEducational factor could be applied in engaging team members. On the alternative, commercial banks should invest in periodic training programs to enhance employee communication skills and EI. Human resources personnel could use these research outcomes to enhance the selection and placement of employees in commercial banks. By these research findings the adequacies of some psychological theories in explaining team effectiveness have been empirically implicated, and the literature on team effectiveness has been increased. Consequently, commercial banks should invest in periodic training programs to enhance employee communication skills and EI, and use these findings to enhance selection and placement in Nigerian banks. It is evident from the results of the present study that the more educated team members are the more likely their teams would be effective in the teamwork. However, periodic training (both off the job and on the job) on EI and its pertinent dimensions, and adoption of appropriate communication styles, could be used to compliment educational deficiencies. Thus, the less educated persons could function adequately in teams if they receive the empowerment. The human resources managers are to note that new bank employees would be better team players when there are adequate orientated on programs on how towards effective to communicate at teamwork functions.Social implicationsIt is evident from these research findings that EI and appropriate organizational communication are behavioral tools that could enhance team interaction and consequently improve team effectiveness.Originality/valueIt is revealed how teams could be made effective through the combined factors of EI and organizational communication, especially among bank employees in Nigeria. Unlike some other studies, this research discovered the specific EI factors that could enhance team effectiveness, not just general EI. It empirically validated some theories that are proposed in relation to EI and organizational communication. This study showcased how teams could be made more effective in the banking sector of the Nigerian economy.
