Hawaii Family Leave Law (HFLL) vs. FMLA: Extended Family Care Allowances

Current as of: October 15, 2026 Employment Law Hawaii
The Hawaii Family Leave Law (HFLL) requires employers with 100 or more workers to provide up to 4 weeks of unpaid leave to care for extended family members, including grandparents, parents-in-law, and reciprocal beneficiaries-categories not covered by federal FMLA.

Understanding the Differences Between HFLL and FMLA

Balancing a demanding job in Honolulu, Kailua, or Waipahu while caring for a sick family member is incredibly stressful. Fortunately, employees in Hawaii are protected by both federal and state laws. While many workers are familiar with the federal Family and Medical Leave Act (FMLA), Hawaii has its own unique statute: the Hawaii Family Leave Law (HFLL). Understanding where these two laws overlap and where they differ is crucial for employees seeking time off, as well as for HR departments trying to remain compliant. HFLL provides specific allowances for extended family care that the federal government does not recognize.

Extended Family Care Allowances under HFLL

Under federal FMLA, eligible employees receive 12 weeks of unpaid leave, but they can only use it to care for a spouse, child, or parent. Hawaii's state law is much more culturally inclusive. Under Haw. Rev. Stat. § 398-3, an eligible employee is entitled to up to 4 weeks of unpaid family leave each calendar year. Crucially, this 4-week allowance can be used to care for a much broader definition of family.

Caring for Grandparents and Parents-in-Law

In Hawaii's multi-generational households, it is extremely common for workers to act as primary caregivers for aging extended family. Unlike federal law, the HFLL explicitly allows employees to take job-protected leave to care for a grandparent with a serious health condition. Additionally, the law protects your right to take leave to care for your parent-in-law or a grandparent-in-law, recognizing the deep family bonds that extend beyond immediate biological parents.

Supporting Reciprocal Beneficiaries

Hawaii law also recognizes non-traditional family structures. An employee can take HFLL leave to care for a sick "reciprocal beneficiary." This legal status applies to two adults who are legally prohibited from marrying one another (such as a sibling or an aunt and nephew) but who have formally registered their relationship with the state. FMLA provides absolutely no leave rights for reciprocal beneficiaries, making this a uniquely powerful protection for Hawaii residents.

How HFLL Interacts with Employer PTO Policies

HFLL applies strictly to employers who have 100 or more employees for each working day during each of 20 or more calendar weeks in the current or preceding calendar year. Just like FMLA, HFLL is generally unpaid leave. However, under Haw. Rev. Stat. § 398-4, an employee has the legal right to substitute up to 10 days of their accrued paid sick leave for unpaid HFLL leave. Your employer cannot stop you from using your sick pay to care for your grandparent, provided you have accrued the time. You may also choose to substitute paid vacation or personal time off (PTO) according to your company's policy.

Medical Certification Requirements

Employers have the right to request proof that your family member actually needs care. To approve the leave, your HR department will typically require a medical certification. While federal leave uses Form WH-380-F, FED, U.S. Department of Labor, Certification of Health Care Provider for Family Member's Serious Health Condition, for HFLL-specific leave (like for a grandparent), your employer may use a custom state-compliant form. The certification must confirm that the family member has a serious health condition and that your presence is necessary to provide care or psychological comfort. The Department of Labor and Industrial Relations, Honolulu enforces these medical certification rules to ensure employers do not ask overly intrusive medical questions.

Frequently Asked Questions (FAQ)

Do HFLL and FMLA run concurrently?

Yes. If you take leave for a reason that qualifies under both laws (like caring for a sick child), the 4 weeks of HFLL will run at the same time as your 12 weeks of FMLA. You do not get 16 weeks total in this scenario.

What if I work for a small business with only 50 employees?

If your employer has 50 employees, they are subject to federal FMLA, but they are exempt from the Hawaii Family Leave Law (which requires 100+ employees). Therefore, you would not be legally entitled to take leave specifically for a grandparent.

Can I use HFLL for my own medical condition?

No. HFLL is strictly for the birth/adoption of a child or to care for a family member with a serious health condition. For your own illness, you would rely on FMLA or Hawaii's Temporary Disability Insurance (TDI).

Can my employer fire me while I am on HFLL leave?

No. HFLL provides strong job protection. Upon returning from HFLL leave, your employer is legally required to restore you to your original position or a completely equivalent position with equal pay and benefits.
