This document summarizes the results of an employee well-being assessment conducted at a call center company with 600 agents. The assessment measured well-being across 8 domains and found that facilities, physical health, and psychological health were most closely linked to sickness absence. Employees in the lowest quartile for facilities well-being were over twice as likely to take more than 4 days of sickness absence and 11.5 times more likely to leave the company compared to those in the highest quartile. The assessment identifies priorities such as improving canteen provision, parking, rest areas, shift patterns, and manager awareness training to help boost employee well-being.
