Investing in the health of all employees enhances productivity and avoids unnecessary costs as the workforce ages. Wellness programs produce healthier employees at all ages; on-site clinics save workers time and focus care on prevention and early disease detection, which also lowers costs. Last, it is believed that seniority-based pay sometimes exceeds performance at the latter stages of the life cycle. In these circumstances bringing pay and performance (properly assessed) into closer conformity would likely ease corporate norms surrounding age at retirement.
