Objectives.  This study aimed to explore the work productivity loss (WPL) due to musculoskeletal symptoms (MS) and its explanatory psychosocial, ergonomic and personal factors in Tunisian shoe and leather industry workers.  Methods.  We conducted a cross-sectional survey among 337 workers. We evaluated WPL using the work productivity and activity impairment questionnaire. We used the Nordic questionnaire to assess the MS prevalence, the job content questionnaire of Karasek to examine the psychosocial work environment and the quick exposure check (QEC) tool to estimate the ergonomic exposure levels.  Results.  The mean WPL was 44.9 ± 33%. In the multiple linear regression model, WPL was positively correlated with a history of MS, professional seniority, a rhythm perceived as restrictive, low social support and decision latitude, the number of symptomatic sites and the QEC strain level of the back.  Conclusion.  There was a decline in work productivity due to MS that results from a combination of personal, psychosocial and biomechanical factors. Once addressed, both work productivity and workers’ well-being should be restored.
