An employee is out on leave, and somewhere between covering their work and answering the team's questions, a quieter worry surfaces: am I keeping the right paperwork? Do I need their medical records? Am I supposed to have a file for this? If you are a small Massachusetts employer without an HR department, this is one of those areas where the fear is usually bigger than the actual task.
Here is the reassuring headline before we get into specifics: your job is to keep a tidy administrative trail, not to become a medical records office. Massachusetts Paid Family and Medical Leave is built so the state, not you, collects and evaluates the private medical details. What you keep is smaller, simpler, and mostly things you already touch.
Short answer: Keep records of notices and acknowledgments, contributions, DFML correspondence, leave dates, and accommodation requests. Keep any medical information confidential and stored separately from the personnel file. And remember that under PFML you should not be collecting private medical diagnoses in the first place; the state handles that part.
What you actually need to document
Think of your leave file as an administrative record, not a medical one. The goal is to be able to show, later, that you handled the leave correctly and treated the employee fairly. That comes down to a handful of things.
Keep the notice acknowledgments. When you gave the employee the required PFML notice, they should have signed or acknowledged receipt. Hold onto that. Keep your contribution and remittance records too, since those show you have been paying into the PFML system correctly. If the Department of Family and Medical Leave (DFML) sends you anything about the employee's application, keep that correspondence and keep a copy of your response and the date you sent it.
Then there is the everyday shape of the leave itself: the dates it started and is expected to end, any intermittent schedule, and confirmation of the employee's return. If the employee asked for an accommodation before or after the leave, document the request and the conversation you had about it. And keep proof that you continued their health insurance on the same terms while they were out.
That is the whole picture. Notice what is not on the list: diagnoses, doctor's notes, and detailed medical histories.
The part that surprises most employers: you are not the medical adjudicator
Under PFML, the employee applies directly to DFML, and DFML handles the medical certification. The state decides whether the medical situation qualifies. You are not the one collecting a diagnosis or judging whether the condition is serious enough. That is genuinely not your role, and stepping into it creates risk rather than protection.
So if you find yourself thinking "I should probably ask for a doctor's note to keep on file," pause. For a PFML claim, you usually do not need one, and gathering medical details you have no business holding can expose you to a privacy or discrimination complaint. Let the state do the medical part. Your file stays clean.
There is a narrow exception. If you also have an FMLA obligation, or an employee gives you medical information tied to an accommodation, you may end up holding some health information. When that happens, the rule is strict, and it is the single most important thing in this whole guide.
The confidentiality rule you cannot get wrong
Any medical information you do receive must be kept confidential and stored separately from the employee's regular personnel file.
This is not a suggestion or a nice-to-have. Under the ADA and federal FMLA, medical certifications, health details, and anything describing an employee's condition have to live in a separate, access-restricted file, not tucked in with performance reviews, pay stubs, and offer letters. A locked drawer or a permission-restricted digital folder that only you (or whoever administers leave) can open is the standard.
A practical test: if you handed someone the employee's regular personnel file, would they see any medical information? If yes, it is filed wrong. Medical documents belong in their own locked spot, full stop.
The reason is simple. Personnel files get pulled for all kinds of reasons: a manager reviewing performance, a reference check, a promotion discussion. Medical information should never ride along with those. Keeping it separate protects the employee's privacy and protects you from a very avoidable claim.
A real-world example
A twelve-person marketing firm had an employee go out on bonding leave after a birth. The owner, wanting to be thorough, emailed the employee asking for a copy of the birth documentation and the medical certification "for our records," then saved it in the shared drive folder where the team kept onboarding paperwork.
Nothing bad happened because of the leave. The problem was the paperwork. The medical document sat in a folder several people could open, and the owner had requested information PFML never required her to collect. When the employee returned and later raised an unrelated concern, that stray medical file became an awkward liability the firm had to untangle.
The fix was almost embarrassingly simple. She did not need the birth documentation at all; DFML had already handled the certification. She deleted it from the shared drive, moved the one legitimate accommodation note into a locked, access-restricted folder, and kept only the administrative records: the notice acknowledgment, the leave dates, the insurance-continuation proof, and her DFML correspondence. Cleaner file, less risk, and less work.
How long to keep it: a records-retention table
Retention periods vary by document type. When two rules overlap, keep the record for the longer period. Here is a working guide for a small Massachusetts employer.
| Record | Keep it in | Minimum retention |
|---|---|---|
| Signed PFML notice acknowledgment | General leave/personnel file | Per your policy; 3+ years is safe |
| Contribution and remittance records | Payroll/tax records | At least 3 years |
| DFML correspondence and your responses | General leave file | At least 3 years after leave ends |
| Leave start/end dates and schedules | General leave file | At least 3 years after leave ends |
| Payroll records covering the leave period | Payroll records | At least 3 years (MA wage law) |
| Health insurance continuation proof | General leave file | At least 3 years after leave ends |
| Accommodation requests and interactive-process notes | Separate accommodation file | At least 3 years after the request |
| Medical certifications or health information (if received) | Separate, locked/confidential file | At least 3 years (FMLA); keep confidential the whole time |
When in doubt, three years after the leave ends is a sound default, and longer if there is any hint of a dispute, since you want the record on hand if a claim surfaces later. For the payroll side of all this, how payroll works during Massachusetts PFML walks through what you are and are not paying while an employee is out.
Your recordkeeping checklist
Work down this list once at the start of a leave, then check back when the employee returns.
- File the signed PFML notice acknowledgment where you can find it later.
- Keep your contribution and remittance records current.
- Save any DFML correspondence, plus your responses and the dates you sent them.
- Record the leave start date, expected end date, and any intermittent schedule.
- Keep proof you continued health insurance on the same terms.
- Document any accommodation request and the conversation around it, separately.
- Move any medical or health information into a locked, access-restricted file.
- Do not request diagnoses or doctor's notes you do not actually need.
- Confirm and record the employee's return date.
- Set a reminder to retain the file for at least three years after leave ends.
If you want the wider view of everything on your plate for a leave, the Massachusetts PFML employer checklist puts recordkeeping in context with the rest of your obligations.
Common mistakes
The errors here are almost always about collecting too much, not too little.
The first is asking for medical documentation you do not need. For a PFML claim, the state handles certification, so a request for a diagnosis or doctor's note usually means you are holding sensitive information with no reason to have it. Less is safer.
The second is mixing medical information into the general personnel file. Even one certification saved in the wrong folder breaks the confidentiality rule. Medical documents get their own locked, separate home, every time.
The third is going silent and keeping nothing at all. Some employers overcorrect and document too little, then cannot show they gave proper notice or continued insurance. The administrative trail matters; it is the medical detail you skip, not the paperwork.
The fourth is contacting the employee too often "to keep the file updated." Checking in constantly during leave is its own risk. If you are unsure what contact is appropriate, can I contact an employee while on leave draws the line clearly.
What to hold onto
Recordkeeping during leave sounds like a compliance minefield, but for a Massachusetts employer it comes down to two habits. Keep a clean administrative trail of notices, contributions, dates, insurance, and DFML correspondence. And keep any medical information you happen to receive confidential and stored separately, always. You are not the medical adjudicator, so you do not need to act like one. A tidy file and a locked drawer will carry you through almost every leave you ever administer. Recordkeeping is just one piece of your broader Massachusetts PFML employer responsibilities, and handling it well makes the rest of those duties easier to prove.
