Healthy Families Act This bill provides for paid and unpaid sick leave for employees to meet their own medical needs and those of their families. It requires employers with 15 or more employees to provide their employees with at least one hour of earned paid sick leave for every 30 hours worked, up to a maximum of 56 hours of paid sick leave in a year. An employer with fewer than 15 employees may also provide the same amount of paid sick leave, but may opt out of such requirement, in which case such employer must provide its employees at least 56 hours of unpaid leave in a year. An employee may use sick leave for absences (1) resulting from a physical or mental illness, injury or medical condition; (2) resulting from obtaining professional medical diagnosis or care, or preventive medical care; (3) to care for a child, parent, spouse, a domestic partner, or other blood or close relative; and (4) resulting from domestic violence, sexual assault, or stalking. The bill makes it unlawful for any employer to interfere with, restrain, or deny the exercise of an employee's right to accrue sick leave as provided by this bill. An employee may take legal action to enforce the right to sick leave granted by this bill and the Department of Labor must investigate complaints of violations of the requirements of this bill. Labor is authorized to conduct a public awareness campaign to educate and inform the public of the requirements for paid sick leave provided by this bill.
