Sick leave wages subject to the $200 per day limit

Employers could provide Coronavirus sick leave-

Two weeks (up to 80 hours) of paid sick leave at two-thirds the employee’s regular rate of pay because the employee is unable to work because of a bona fide need to care for an individual subject to quarantine (pursuant to Federal, State, or local government order or advice of a health care provider), or care for a child (under 18 years of age) whose school or child care provider is closed or unavailable for reasons related to COVID-19, and/or the employee is experiencing a substantially similar condition as specified by the Secretary of Health and Human Services, in consultation with the Secretaries of the Treasury and Labor.
