This study aims to examine the effects of occupational stress and lack of personal accomplishment on the perceived productivity of academic staff in primary schools in the state of Kuwait with positivity as a moderator. To fulfil this objective, some reliable and validated measurement techniques were used to clarify the amount of stress, lack of personal accomplishment, productivity, as well as positivity of respondents, and to recognize the relationship between variables accordingly. The research adopted a stratified random sampling and selected 379 individuals from the English departments of primary schools throughout all Kuwait educational zones. The data was analyzed using SPSS and SmartPLS. Findings revealed that occupational stress and lack of personal accomplishment proved to significantly affect the perceived productivity of the English academic staff in primary schools in Kuwait. As for positivity, it fully moderated the correlation between occupational stress and perceived productivity, but it did not act as a moderating factor in the correlation between lack of personal accomplishment and perceived productivity. Both theoretical and practical implications of the study’s findings were examined to reduce stress and lack of personal accomplishment and boost perceived productivity. Limitations and recommendations for future research were also highlighted.
