Sick Leave

Sick leave provides employees with paid time off when they are ill or need to care for a sick family member — a benefit that is legally mandated in many countries and in an increasing number of US states and localities, but optional at the federal level for US private sector employees. Emerging sick leave policy design has evolved from pure illness-focused policies toward wellbeing leave — covering mental health days, preventive care appointments, and caregiver obligations alongside acute illness — recognizing that the boundaries between physical illness, mental health, and caregiver stress are functionally inseparable in the modern workforce. The most practically significant sick leave policy debate is whether to use separate sick leave banks or integrated PTO: integrated PTO pools reduce HR administration complexity but can lead employees to save PTO for vacation rather than using sick time when genuinely ill.
