Group 4: Productivity Losses WRMSDs increase the potential for loss in productivity and reduction in quality (from increased errors from injury). Longer hours and consequent overtime costs, resulting from unplanned worker absenteeism from injury, leads to an increase in the workload of the remaining workers and may further increase potential for further injuries. Statistics of lost-time-claims cost and productivity loss statistics show billions of dollars in lost productivity costs in several European countries (Schneider et al. 2010, Chapter 4).
