Massachusetts Issues Guidance on PFML and FMLA Overlap

What Changed

The Commonwealth of Massachusetts released both a brief guide and in-depth guidelines explaining the interaction between the state's Paid Family and Medical Leave (PFML) program and the federal Family and Medical Leave Act (FMLA). The guidance addresses a common source of confusion for employers: when and how these two leave programs overlap, run concurrently, and differ.

The guidance clarifies key points including concurrent leave requirements, benefit stacking, PTO supplementation rules (effective November 1, 2023), and the distinction between PFML's wage replacement benefits and FMLA's job protection.

Who Is Affected

All Massachusetts employers subject to both PFML and FMLA — which includes most employers with 50 or more employees (FMLA threshold) as well as smaller employers who participate in the Massachusetts PFML program. HR professionals and leave administrators responsible for coordinating multiple leave programs will find this guidance particularly relevant.

Where It Applies

Massachusetts statewide. The guidance applies to all employers and employees covered under the Massachusetts PFML program.

When It Takes Effect

The guidance is effective immediately upon release. The PTO supplementation provision — which allows employees to "top off" their PFML benefit with accrued PTO up to their individual average weekly wage — applies to leave applications filed on or after November 1, 2023.

Why It Matters

The overlap between PFML and FMLA is one of the most common areas where employers make administrative errors. Running the two programs concurrently when the leave qualifies under both is generally required, but the mechanics of coordination — including tracking separate entitlements, managing benefit payments, and handling return-to-work obligations — are nuanced. Errors can result in providing less leave than required (creating legal exposure) or more leave than necessary (creating operational burden).

The PTO supplementation change is particularly notable: employees can now use accrued PTO to supplement PFML benefits, which may affect employers' PTO liability calculations.

The Humareso Take

If you have Massachusetts employees and you've been winging it on how PFML and FMLA interact, this guidance is worth reading carefully. The state has done a good job of laying out the rules in practical terms. The PTO supplementation change coming in November is the piece we'd flag most urgently — it changes the financial dynamics of leave for both employers and employees, and your payroll team needs to know about it. We recommend using this guidance as the basis for an internal training session with your leave administrators.

Recommended Action Steps

1. Review the Massachusetts PFML/FMLA overlap guidance available on the Mass.gov PFML website.

2. Train leave administrators on the rules for running PFML and FMLA concurrently, including tracking separate entitlement banks.

3. Update leave administration procedures to account for the PTO supplementation provision effective November 1, 2023.

4. Review your PTO policy to determine how supplementation will affect accrued PTO balances and liability.
