| Recommendations to score |
Lost hours per week due to absenteeism = (total illness hours + total short-term disability hours)/weeks employment Lost hours per week due to failure to meet productivity standard = [100% - (Overall Score if <0.5)/(0.5=] x Average weekly staffing hours Total lost hours per week = lost hours per week due to absenteeism + lost hours per week due to failure to meet productivity standard |
| Score Interpretation | presenteesim ratio ≥ 0.5 lost 0 hours per week; <0.5: evaluated as proportion of 100% to gain an estimate of hours/week that employee wasn’t attaining productivity standard |
