Paid sick days for working parents can enhance children’s school success. Parents face a difficult choice if their children get sick when they lack paid sick days: staying home with the child and missing pay (and possibly facing discipline at work); sending the child to school sick, which compromises their school performance and spreads illness to others; leaving the child at home alone, putting the child at risk; leaving the child with an older sibling who in turn must stay home from school; or trusting the child to a temporary caregiver. Each of these scenarios has potential costs for schools or for child well-being.
