Massachusetts does mandate sick leave, and the core rule is precise: under the Massachusetts Earned Sick Time Law (M.G.L. c. 149, § 148C), most employees earn 1 hour of sick time for every 30 hours worked, up to a cap of 40 hours per year. Whether that time is paid or unpaid turns on employer size: if your employer has 11 or more employees, the earned sick time must be paid at your regular hourly rate. If your employer has 10 or fewer employees, you still earn the same 40 hours, but the employer may provide it unpaid (job-protected) rather than paid. This is a statewide right that applies on top of the federal baseline, which guarantees no paid sick leave at all for private-sector workers.
The Massachusetts rule in detail
The Earned Sick Time Law took effect on July 1, 2015, and covers nearly all Massachusetts workers, including full-time, part-time, seasonal, and temporary employees. There is no minimum hours threshold to start earning, and there is no exemption for small businesses from the accrual requirement itself, only from the obligation to pay for the time.
Accrual rate: 1 hour of earned sick time for every 30 hours actually worked.
Annual cap: Employers must let you accrue and use at least 40 hours of earned sick time per benefit year.
When accrual starts: You begin accruing on your first day of work (or July 1, 2015, whichever was later).
When you can use it: Employers may require a 90-day waiting period before you use accrued time, but you keep accruing during those 90 days.
Carryover: You may carry over up to 40 hours of unused earned sick time into the next year. However, an employer is never required to let you use more than 40 hours in a single year. Employers can avoid carryover bookkeeping by front-loading 40 hours at the start of the year.
Increments: Time can generally be used in hourly increments, or in the smallest increment the employer's payroll system uses to account for absences.
Who counts as an "employee" for size purposes
To determine whether you get paid or unpaid sick time, count all employees of the business, including full-time, part-time, and temporary workers, based on the average number employed per pay period over the prior benefit year. A business that crosses the 11-employee line during the year generally must provide paid sick time to all employees for the remainder of that year. If you are not sure how your employer counts, the headcount is something you can ask about or raise with the enforcing agency.
What you can use earned sick time for
The law lists specific covered uses. You can take earned sick time to:
Care for your own physical or mental illness, injury, or medical condition that needs home care, professional diagnosis, or treatment.
Care for a child, spouse, parent, or parent of a spouse who is ill, injured, or needs medical diagnosis, care, or preventive care.
Attend your own or a covered family member's routine medical appointments.
Address the psychological, physical, or legal effects of domestic violence on you or your dependent child.
Travel to and from an appointment, pharmacy, or other location related to the purpose for which the time was taken.
You do not have to find a replacement worker to cover your shift, and an employer cannot require that as a condition of using earned sick time.
Notice and documentation
For foreseeable absences (like a scheduled appointment), an employer can require advance notice, generally up to seven days. For unforeseeable needs, you must notify the employer as soon as practicable. An employer may require documentation only when you use earned sick time for more than 24 consecutively scheduled work hours, or for absences of 3 or more consecutive days. Even then, the employer cannot require that the documentation explain the nature of the illness or the details of domestic violence.
Local ordinances
Unlike some states where cities layer their own paid-sick rules on top of state law, Massachusetts applies a single uniform Earned Sick Time Law statewide. There is no significant patchwork of separate city or town paid-sick ordinances that grant rights beyond the state statute. That makes compliance simpler: the same 1-hour-per-30-hours rule and 40-hour cap apply whether you work in Boston, Worcester, Springfield, or a small town. Always confirm with the state, because some municipal employers and collective bargaining agreements may offer more generous terms.
How earned sick time interacts with PTO
If your employer already offers paid time off (PTO), vacation, or a combined leave bank that gives you at least 40 hours of paid leave usable for the same purposes and on the same terms as the Earned Sick Time Law, the employer is considered in compliance and does not have to provide separate sick time on top of it. The key is that the existing policy must be at least as generous in amount, accrual, carryover, and permitted uses. If your PTO policy is more restrictive than the sick-time law in any of those respects, the law's minimums still control.
How it interacts with FMLA and Massachusetts PFML
Earned sick time is separate from, and much narrower than, long-term leave laws. The federal Family and Medical Leave Act (FMLA) provides up to 12 weeks of unpaid, job-protected leave for serious health conditions, but only at employers with 50 or more employees and only for workers who meet tenure and hours tests. Massachusetts also has its own Paid Family and Medical Leave (PFML) program, which provides paid leave (up to 12, 20, or 26 weeks depending on the reason) funded through payroll contributions and administered by the state. Earned sick time fills the gap these programs leave open: it covers short, everyday absences like a sick child or a doctor's visit. You can often use earned sick time during the waiting period or alongside these larger programs, depending on the circumstances.
Pay rate and the minimum wage baseline
When earned sick time is paid, it must be paid at your same hourly rate. Note that Massachusetts's minimum wage is $15.00 per hour as of 2026, well above the federal floor of $7.25 per hour set by the Fair Labor Standards Act. Because minimum-wage figures can change, confirm the current Massachusetts rate with the official state source before relying on it. The federal FLSA, by contrast, requires no paid sick leave for private employers at all, so Massachusetts workers have a meaningful right that federal law does not provide.
How to enforce your rights
Massachusetts law prohibits retaliation against employees for using or requesting earned sick time, and there is a rebuttable presumption of retaliation if you suffer an adverse action within 90 days of exercising your rights. To enforce the law:
Keep your own records of hours worked, sick time accrued, and absences taken.
Raise the issue in writing with your employer or HR first, if it is safe to do so.
File a complaint with the Massachusetts Attorney General's Office, Fair Labor Division, which enforces the Earned Sick Time Law and investigates violations and retaliation.
To verify the current rules, accrual details, and complaint procedures, consult the official guidance published by the Massachusetts Attorney General's Office and the Massachusetts Department of Labor Standards. Because YMYL legal rules can be updated, always confirm the latest figures and procedures with these state sources before acting.

Frequently asked questions
Does Massachusetts require employers to pay for sick leave?
Yes, if the employer has 11 or more employees. Those employers must provide paid earned sick time at your regular hourly rate. Employers with 10 or fewer employees must still let you accrue and use the same 40 hours, but they may provide it unpaid while keeping your job protected.
How fast do I earn sick time in Massachusetts?
You earn 1 hour of sick time for every 30 hours you actually work, up to a maximum of 40 hours per benefit year. Accrual begins on your first day of employment, but an employer may require a 90-day waiting period before you can use the time.
Can I carry over unused earned sick time to the next year?
Yes. You can carry over up to 40 hours of unused earned sick time into the following year. However, an employer never has to let you use more than 40 hours in any single year. Employers can avoid carryover by front-loading 40 hours at the start of each year.
Do Massachusetts cities have their own paid sick leave laws?
No. Massachusetts applies one uniform statewide Earned Sick Time Law rather than a patchwork of separate city ordinances. The same accrual rate and 40-hour cap apply across the state, though some union contracts or municipal employers may offer more generous terms.
Who do I contact if my employer denies earned sick time?
The Massachusetts Attorney General's Office, Fair Labor Division enforces the Earned Sick Time Law. You can file a complaint there, and the law presumes retaliation if you face an adverse action within 90 days of using or requesting earned sick time.
