Enacts the "paid sick leave act"

S 4304, the "Paid Sick Leave Act," requires all employers (including state/local governments) to provide paid sick leave to employees. Employees earn one hour of paid sick leave for every 20 hours worked, up to 80 hours annually (40 hours for small businesses with fewer than 10 employees), for their own illness, medical care, or caring for family members (including adopted/foster relatives). The law prohibits employer retaliation for using sick leave, mandates workplace posting of employee rights, and requires employers to maintain records for four years. It applies to all employees regardless of work schedule or employment status.
