Key federal employee leave laws HR should understand

Navigating leave requires understanding the types of leave and the laws that govern how and when employees can take time off. Core federal laws include: 

Family and Medical Leave Act (FMLA)

The FMLA provides eligible employees of covered employers of unpaid, job-protected leave in a 12-month period for specified reasons (birth/bonding, adoption/foster placement, care for covered family members with a serious health condition and certain military exigency caregiver reasons).   

During FMLA leave, employers must maintain group health insurance under the same terms as if the employee were working and generally restore the employee to their same or an equivalent position. Employers are also prohibited from interfering with FMLA rights, and compliance is enforced by the U.S. Department of Labor. 

Americans with Disabilities Act (ADA)

The Americans with Disabilities Act (ADA) is a federal law that prohibits disability discrimination and requires reasonable accommodations for qualified individuals with disabilities, unless doing so would cause an undue hardship. While the ADA is not a leave law, leave is often requested as a reasonable accommodation, especially after an employee has exhausted their FMLA leave. Employers are required to engage in an interactive process with employees to determine appropriate accommodations and must maintain confidentiality regarding employees’ medical information.

Uniformed Services Employment and Reemployment Rights Act (USERRA)

The USERRA is a federal law that applies to all public and private employers, regardless of size. USERRA provides detailed rights regarding leave, reinstatement, and non-discrimination for members of the uniformed services.

It covers all employees except those in brief, nonrecurring positions without a reasonable expectation of continued employment. The law encompasses various forms of military service, including active duty, training, and certain disaster response duties.

Under USERRA employers are required to:

• Inform employees of their rights and obligations
• Ensure that servicemembers are protected from discrimination
• Servicemembers have the right to reinstatement after their service

Pregnancy Discrimination Act (PDA)

The Pregnancy Discrimination Act (PDA) is a federal law that prohibits discrimination against employees and applicants based on pregnancy, childbirth, or related conditions and requires employers to treat pregnant workers the same as others similar  in their ability or inability to work. For example, requests for leave prior to the birth of the child for related medical conditions must be treated under the same terms and conditions applied to employees with other types of medical conditions.

The PDA covers a wide range of situations, including:

• Current pregnancy
• Past pregnancy
• Potential pregnancy
• Medical conditions related to pregnancy or childbirth.

How do state and local leave laws affect employer requirements?

State and local leave laws frequently add leave entitlements beyond federal law, such as paid sick leave, paid family and medical leave, voting leave, domestic violence leave and other protected leave.

Multistate employers must learn about the leave laws in each state they operate in or have employees working, including remote/hybrid workers. These laws can be very different and may add extra requirements beyond federal law.

Employers can offer better leave rights than the law requires. However, they need to understand state and local laws to avoid legal issues.

Because laws change regularly, multistate employers must track and apply the correct law(s), providing the greatest benefits from each applicable law to the employee. Failing to comply can result in back pay, fines, reinstatement orders and reputational risk. 

What makes leave management challenging for HR teams?

Employee leave management can quickly become complex, especially as workforce needs and regulations evolve. HR teams often face challenges such as:

• Coordinating overlapping leave types (sick leave, FMLA, ADA-related leave, parental leave, PTO and state-specific programs) 
• Managing multistate compliance, where each jurisdiction has different notice, documentation and eligibility rules 
• Ensuring fairness and consistency when handling similar requests across departments or managers 
• Documenting every step properly to protect against disputes, audits or legal claims 
• Tracking intermittent or reduced-schedule leave, which requires precise recordkeeping and regular communication 
• Balancing operational needs while supporting employee health, family obligations and work-life balance 

HR teams face challenges that can impact compliance, productivity, and morale. They benefit from tools and processes that lower administrative tasks. These tools also help ensure consistent decision-making.
