Ringkasan	The Work Ability Index (WAI) measures workers' capacity to perform their current job given their health status, job demands, and life circumstances. Developed by Finnish occupational health researchers, the WAI captures the dynamic relationship between personal capacity (physical fitness, mental health, skills) and job demands, identifying workers at risk of sickness absence, work disability, and early retirement. The WAI is a leading indicator for occupational health intervention, used in occupational health surveillance, rehabilitation, and aging worker management.	The Employee Wellbeing Scale (EWS) measures workers' subjective wellbeing across five dimensions: vitality (energy and physical health), motivation (engagement with work), self-perception (confidence and self-worth), social connection (relationships and belonging), and general life satisfaction. Developed by Page and Vella-Brodrick, the EWS captures holistic employee wellbeing—the balance of psychological, social, and physical health that enables people to thrive at work and in life. The scale is used for occupational health surveillance, evaluation of workplace wellness interventions, and organizational culture assessment.
