Massachusetts HR Compliance Guide for Employers

This guide covers every major employment law requirement for Massachusetts employers as of 2026, with particular focus on the rules that small businesses without a dedicated HR person run into first. It matters because compliance mistakes here carry severe financial consequences, and assumptions borrowed from federal law or neighboring states frequently lead employers astray.

Massachusetts combines some of the country's most protective wage laws with a recording consent statute that carries felony penalties, a non-compete framework unlike any other state's, a state-run paid family and medical leave (PFML) program, and an anti-discrimination law, Chapter 151B, that kicks in at six employees.

The Wage Act's mandatory treble damages are perhaps the most consequential single rule. Any violation, including a one-day delay on a final paycheck, triggers automatic damages of three times the unpaid wages plus attorney fees, and there is no good faith defense. The Massachusetts Supreme Judicial Court (SJC) applied the trebling to wages paid late in Reuter v. City of Methuen (2022).

What Makes Massachusetts Unique for Employers

Massachusetts is one of the most complex and demanding states in the country for employers. Several of its rules have no parallel in federal law or in most other states.

Seven areas stand out as particularly distinctive, especially if you are expanding into Massachusetts from another state:

The Wage Act treble damage rule is the first and most important. Under M.G.L. c. 149, §§ 148 and 150, any violation of wage payment requirements triggers mandatory damages of three times the unpaid wages plus attorney fees and costs. Corporate officers are personally liable. There is no defense based on good faith or honest mistake.

Massachusetts is an all-party consent state for audio recordings, and violation is a felony under M.G.L. c. 272, § 99, carrying penalties of up to $10,000 and five years in state prison. Employers cannot secretly record any call, meeting, or conversation. The standard is whether the recording is secret, not whether all parties consented.

The Massachusetts Noncompetition Agreement Act (MNCA) requires every non-compete to be backed by consideration. One option is garden leave, meaning pay during the restricted period: 50% of the employee's highest annualized base salary over the prior two years, paid pro-rata throughout. The other is consideration that both sides agree to and write into the agreement.

The PFML program is a state-run insurance system, not an employer-funded leave program. Employees contribute, employers with 25 or more covered individuals contribute as well, and employees receive benefits directly from the state. The 2026 maximum weekly benefit is $1,230.39.

Chapter 151B anti-discrimination law covers employers with six or more employees, well below the federal threshold of 15, and protects 14 or more classes. Punitive damages are uncapped in Massachusetts Superior Court.

Any employer storing personal information of Massachusetts residents must maintain a Written Information Security Program (WISP) under 201 CMR 17.00, regardless of where the employer is located or how many employees they have.

Sunday and holiday premium pay for retail workers was fully eliminated effective January 1, 2023. Many online resources still reference these premiums as current requirements. The voluntariness provisions that prevent retailers from requiring employees to work Sundays or holidays remain in effect.

Employment Law Foundations in Massachusetts

Massachusetts is an at-will employment state, but with a notably broad set of statutory and common law exceptions compared to most states.

At-will employment and its exceptions

Courts here recognize the public policy exception to at-will employment and the covenant of good faith and fair dealing, and Massachusetts is one of a small number of states that applies that covenant in employment contexts. An employee handbook can also create contractual obligations under the implied contract doctrine, so clear at-will language is essential for Massachusetts employers.

Statutory anti-retaliation protections span the Wage Act, Chapter 151B, PFML, and workers' compensation. The state whistleblower act at M.G.L. c. 149, § 185 is narrower than its name suggests. It defines an employer as the Commonwealth, its agencies and political subdivisions, and gas and electric utilities, so a private business outside those categories is not covered by it.

Right to work status

Massachusetts is not a right to work state. Federal labor law at 29 U.S.C. § 164(b) lets a state prohibit agreements that make union membership a condition of employment, and Massachusetts has never passed one. Union security clauses, the contract terms that tie a job to union membership or dues, are lawful here for private sector employees.

For a business whose workers have no union, the practical effect is nothing, because these rules only operate once a workplace has one. Where it matters is a first contract: a union that wins an election can bargain for a clause requiring bargaining unit employees to pay dues or an equivalent fee, and no Massachusetts statute stands in the way.

Public employers are the exception, and the exception comes from federal constitutional law rather than from the Commonwealth. After Janus v. AFSCME (2018), agency fees cannot be collected from public employees who decline to join the union, whatever the collective bargaining agreement says.

Massachusetts Commission Against Discrimination (Chapter 151B)

Chapter 151B applies to employers with six or more employees and covers race (including hair texture and protective hairstyles under the 2022 CROWN Act), color, religious creed, national origin, sex, pregnancy and related conditions including lactation, gender identity, sexual orientation, genetic information, ancestry, age (40 and older), disability, veteran and military status, and criminal record.

The filing clock at the Commission (MCAD) is long by federal standards. Per the MCAD filing deadline guidance, a complaint must be filed within 300 days of the act claimed to be unlawful, with narrow case-by-case extensions.

The bigger exposure comes later. After 90 days in the MCAD process, an employee may remove the case, taking it out of the agency and into Superior Court, where Massachusetts caps neither compensatory nor punitive damages. That is a real distinction from federal Title VII, whose caps under 42 U.S.C. § 1981a run $50,000 to $300,000 by employer size.

Massachusetts Wage Act

The Wage Act at M.G.L. c. 149, §§ 148-150 is the strictest wage law in the country. Mandatory treble damages apply to every violation without exception. The statute of limitations is three years. Corporate officers with financial management authority are personally liable for violations.

Employees may file a complaint with the Attorney General's office and then bring a private lawsuit after 90 days. If the employee wins, Section 150 makes the trebling mandatory. The SJC's 2022 decision in Reuter v. City of Methuen, 489 Mass. 465, held the employer liable for three times the wages it had paid late.

Hiring and Onboarding Requirements

Massachusetts new hire paperwork involves more required documents at hire than most states, including multiple mandatory written notices and strict criminal history rules.

CORI and ban-the-box

Massachusetts prohibits asking about criminal records (Criminal Offender Record Information, or CORI) on the initial written job application under M.G.L. c. 151B, § 4(9½). At any stage of the process, employers may never ask about arrests that produced no conviction; sealed or expunged records; juvenile records; or first convictions for drunkenness, simple assault, speeding, minor traffic offenses, affray (a public fight), or disturbance of the peace.

Misdemeanor convictions fall away on a three-year clock. Per the Attorney General's guide to criminal records in employment, an employer may not ask about a misdemeanor once three years have passed since the conviction or since the person completed any incarceration for it, unless that person has been convicted of some other offense inside those three years.

What the report itself shows is a separate question. Employers get Standard Access to CORI from the Department of Criminal Justice Information Services, and per the DCJIS guide to CORI access levels, that level returns pending charges, felony convictions for ten years, and misdemeanor convictions for five years.

Both report clocks run from the disposition (how the case ended) or the release from incarceration. Murder, manslaughter, and sex offense convictions show with no time limit at all.

Consumer reporting agencies working for an employer are held to a tighter rule: no record of arrest, indictment, or conviction that antedates (is dated before) the report by more than seven years from disposition, release, or parole, under M.G.L. c. 93, § 52.

Two paperwork rules round this out. Employers conducting five or more background checks per year must have a written CORI policy, and the applicant must receive a copy of the criminal record before any adverse decision based on it.

Pay transparency in job postings

Employers with 25 or more employees must include a pay range in all job postings from October 29, 2025. The rule comes from An Act Relative to Salary Range Transparency, signed July 31, 2024 as St. 2024, c. 141, which the Attorney General calls the Wage Transparency Act.

The statute reaches any advertisement or posting, whether the employer recruits directly or through a third party, and the range must be what the employer reasonably and in good faith expects to pay.

The duty does not stop at the posting. Per the state pay transparency guidance, an employer must also give the range to an applicant or a current employee who asks for it, and to an employee who is offered a promotion or a transfer.

Enforcement is unusually gentle, and deliberately so. A first violation draws a warning, a second up to $500, and a third up to $1,000. The Attorney General enforces exclusively, there is no private right of action, and these violations do not trigger Wage Act treble damages.

One further obligation rides on the same act and catches larger employers. From February 1, 2025, an employer with 100 or more employees that is subject to federal EEO-1 filing must also submit its most recent EEO-1 report to the Commonwealth, which passes it to the Executive Office of Labor and Workforce Development.

Drug testing

Massachusetts has no comprehensive drug testing statute for private employers. Testing is governed by case law and the privacy statute at M.G.L. c. 214, § 1B. Per the Trial Court Law Libraries summary of employee privacy law, courts following Webster v. Motorola, 418 Mass. 425 (1994), judge a random testing mandate case by case, weighing each employee's right to privacy against the employer's interests.

Medical marijuana is the wrinkle most handbooks get wrong. In Barbuto v. Advantage Sales and Marketing, 477 Mass. 456 (2017), the Supreme Judicial Court held that an employee registered for medical marijuana may be owed a reasonable accommodation for off-duty use, depending on the position and the circumstances. Recreational users get no equivalent protection.

Wage and Hour Rules That Catch Employers Off Guard

Massachusetts wage and hour law contains several rules that differ significantly from the federal FLSA (Fair Labor Standards Act) and from most other states, with penalties more severe than anywhere else in the country.

Minimum wage and service rate

The Massachusetts minimum wage is $15.00 per hour under M.G.L. c. 151, § 1. According to the Massachusetts minimum wage and overtime guidance, that rate took effect on January 1, 2023 as the final step of the Grand Bargain phase-in. Agricultural workers have a separate rate of $8.00 per hour.

Section 1 writes the rate as a flat dollar figure, with no CPI indexation (no automatic inflation adjustment) and no further step scheduled, so any future raise takes a new law or a ballot question. The same section keeps the state rate at least 50 cents above the federal minimum, a floor that stays dormant while the federal rate sits at $7.25.

The service or tipped rate is $6.75 per hour, leaving a tip credit of $8.25. If tips plus the service rate do not reach the full $15.00, the employer pays the difference, and that top-up is calculated at the end of each shift rather than at the end of the pay period.

M.G.L. c. 149, § 152A adds two limits on tips. Employers and managers may not participate in tip pools, and service charges go only to wait staff, service employees, and service bartenders.

Rates move, and the Boston living wage for city contractors moves separately from the state figure. The Massachusetts minimum wage page carries the current rate, the service and agricultural rates, and why city living wage ordinances reach only city departments and contractors rather than private employers generally.

Overtime

Massachusetts requires 1.5 times the regular rate for hours over 40 per week under M.G.L. c. 151, § 1A. There is no daily overtime threshold. A broad list of employer categories is exempt from the overtime requirement, including hotels, restaurants, hospitals, gas stations, and seasonal businesses.

Commission pay is the trap here. In Sullivan v. Sleepy's LLC, 482 Mass. 227 (2019), the Supreme Judicial Court held that overtime owed to a commissioned salesperson has to be a separate and additional payment, on top of the commission, rather than something a draw or a commission can be credited against.

Employees with no hourly rate at all follow a simpler rule: their overtime premium is calculated on the prevailing minimum wage.

Mandatory meal breaks

Under M.G.L. c. 149, § 100, employers must provide a 30-minute meal break to anyone working more than 6 hours in a calendar day. The break may be unpaid only if the employee is completely relieved of duties and free to leave the premises. An employee may voluntarily work through it, but time worked at the employer's request is paid.

The state guidance on breaks and time off sets out that duty-free standard, and breaking it is expensive. The penalty is criminal, not civil: Section 100 punishes an employer, superintendent, overseer, or agent who violates it with a fine of not less than $300 and not more than $600.

Pay deductions add a second violation. Requiring an employee to work through a break and then deducting the time from their pay also violates the Wage Act, which pulls in mandatory treble damages.

Rest breaks and the 15-minute break question

Massachusetts does not require rest breaks. The 30-minute meal break above is the only break the state mandates, and no statute entitles employees to a 15-minute break in the morning or the afternoon. Employers are free to offer them, and most do, but the obligation then comes from company policy or a collective bargaining agreement rather than from M.G.L. c. 149.

What the law does control is whether a short break is paid. Under DOL Wage and Hour Division Fact Sheet #22, rest periods of 20 minutes or less count as hours worked, which means they are paid and they count toward the 40-hour overtime threshold. Deducting a 15-minute break from a timesheet is a wage violation, and in Massachusetts that means treble damages.

Two practical consequences follow. A meal break interrupted by work is not a bona fide (real) meal break, so an employee called back to the counter mid-break has worked those minutes and is owed them. And where a handbook promises rest breaks, the handbook becomes the source of the obligation under the implied contract doctrine described above.

Sunday and holiday premium pay: eliminated

The Grand Bargain phase-out of Sunday and holiday premium pay for retail workers completed on January 1, 2023. The premium rate stepped down from 1.5 times in 2018 to 1.0 times over five reductions. Plenty of employers and HR resources still describe Sunday premiums as a live requirement. They are not.

The voluntariness half of the Blue Laws, the state's Sunday and holiday work rules, did survive, and it is the part that still bites. Retailers cannot require employees to work on Sundays or covered holidays, and cannot discipline, penalize, or terminate anyone for refusing. Overtime still applies in the ordinary way: hours past 40 in the week are paid at 1.5 times, Sunday hours included.

Final paycheck rules

When an employer discharges an employee, final wages are due on the day of discharge under § 148. When an employee quits, final wages are due on the next regular payday, or on the following Saturday where there is no regular payday. Final wages include all earned but unpaid wages, accrued vacation time, and commissions that are definitely determined and due.

Vacation is the item policies most often get wrong. Per the Trial Court Law Libraries summary of vacation law, vacation promised under an oral or written agreement counts as wages, so accrued time goes into the final paycheck, and the SJC has held that unused vacation must be paid on an involuntary discharge. A use-it-or-lose-it-at-separation clause does not change that.

The day-of-discharge rule has no grace period built into it. Paying by direct deposit on the next business day after a termination is a violation, and any late or short payment triggers mandatory treble damages plus attorney fees. Corporate officers with management responsibility for wage payment are personally liable for it.

Equal Pay Act and salary history ban

The Massachusetts Equal Pay Act at M.G.L. c. 149, § 105A took effect July 1, 2018. It prohibits pay discrimination based on gender for comparable work, defined as work requiring substantially similar skill, effort, and responsibility under similar working conditions. That is a broader test than identical work, and it is what makes the statute bite.

Six reasons for a pay difference are permitted, and only six: a seniority system; a merit system; a system measuring earnings by quantity or quality of production, sales, or revenue; geographic location; education, training, or experience reasonably related to the job; and travel that the job requires.

The salary history ban lives in the same section. It bars asking any applicant about prior salary before making an offer, and it bars conditioning consideration on meeting a minimum prior salary level.

Damages run to twice the unpaid wages plus attorney fees, on a three-year statute of limitations that restarts each time affected wages are paid. An employer that completed a good-faith self-evaluation of its pay practices within the three years before the claim, and can show reasonable progress toward closing any gender gap it found, has an affirmative defense to liability.

Earned Sick Time: What Every Massachusetts Employer Must Know

Massachusetts Earned Sick Time under M.G.L. c. 149, § 148C applies to all employers regardless of size. The key distinction is whether the time is paid or unpaid, which depends on headcount.

All employees are counted for threshold purposes: full-time, part-time, temporary, and seasonal workers. Employers with 11 or more employees must provide paid sick time. Employers with fewer than 11 employees must provide unpaid sick time.

Accrual begins on the first day of employment at a rate of one hour per 30 hours worked, up to a cap of 40 hours per year. Employees may begin using accrued time after 90 days of employment. Exempt employees are assumed to work 40 hours per week for accrual purposes.

Earned sick time may be used for the employee's own illness, injury, or medical condition; care for a child, spouse, parent, or parent of a spouse; routine medical or dental appointments; and the effects of domestic violence. St. 2024, c. 186, § 42, effective November 21, 2024, added the employee's own or a spouse's pregnancy loss, and failed assisted reproduction, adoption, or surrogacy.

Paid Family and Medical Leave: Massachusetts's Signature Program

Massachusetts PFML at M.G.L. c. 175M is a state-run insurance program administered by the Department of Family and Medical Leave (DFML). It is not an employer-funded leave benefit. Employees receive their benefits directly from the state, which is why your role as the employer is contribution and verification rather than payment.

The Department of Family and Medical Leave publishes the poster, notices, and rate sheets employers must use.

Leave duration

PFML provides up to 20 weeks per benefit year for medical leave covering the employee's own serious health condition, and up to 12 weeks per benefit year for family leave covering bonding after birth or adoption, caring for a family member's serious health condition, or military qualifying exigency.

Military caregiver leave extends to 26 weeks. The combined maximum across both types is also 26 weeks per benefit year, and PFML runs concurrently with federal FMLA (the Family and Medical Leave Act) for qualifying events.

Premium rates and employer obligations

Per the DFML contribution rate page, employers with 25 or more covered individuals must collect and remit both the employer share and the employee share. Employers with fewer than 25 covered individuals must withhold and remit only the employee share of 0.46%. They have no employer contribution obligation, but they may voluntarily pay some or all of the employee share themselves.

Every employer, whatever its size, must also display the PFML workplace poster, give each new hire written notice within 30 days of hire, and submit quarterly wage detail reports.

Rate and benefit updates

The maximum weekly benefit is $1,230.39 for 2026, based on a State Average Weekly Wage of $1,922.48. The total contribution rate holds at 0.88% of eligible wages up to the Social Security cap of $184,500, split 0.70% medical and 0.18% family.

The federal employment tax treatment is the part employers keep getting wrong. Per IRS Notice 2026-6, the Revenue Ruling 2025-4 transition period runs through calendar year 2026 for the portion of state-paid medical leave benefits attributable to employer contributions. For 2026, neither the state nor the employer has to treat that piece as third-party sick pay or withhold and pay federal employment taxes on it.

One component did lose its transition relief for 2026: the employer pick-up. An employer that voluntarily pays part or all of the employee contribution must treat that amount as wages for federal employment tax purposes and report it on the employee's Form W-2. Small employers that cover the employee share out of goodwill are exactly the ones this catches.

Massachusetts has already legislated its way out of the underlying problem. Chapter 101 of the Acts of 2026, signed June 12, 2026, moves the employer share off medical leave and onto family leave effective January 1, 2027, so no medical leave benefit will be attributable to an employer contribution and none of it will be taxed as wages. DFML sets the 2027 rate on or before October 1, 2026.

Topping off is a separate option worth knowing. For applications filed on or after November 1, 2023, an employee may supplement the PFML benefit with accrued paid leave, so long as the combined weekly total does not exceed their individual average weekly wage. Paid time off used during the seven-day waiting period does not reduce the state benefit either.

Private plan option

Employers may apply to substitute a private plan whose benefits are equal to or greater than the state plan's. The plan needs DFML approval and must maintain those equivalent or greater benefits. An employer with an approved private plan may be exempt from state contributions, but it still owes employees equivalent leave coverage.

Massachusetts FMLA: which law, which form, which office

There is no separate Massachusetts FMLA statute. Employers who ask about it usually mean one of two things: the federal FMLA, which provides 12 unpaid weeks and reaches an employee only when the employer has 50 or more employees within 75 miles of that employee's worksite, or PFML, the state insurance program above, which reaches employees at companies of every size and pays a benefit.

The forms split the same way. A federal FMLA certification runs on the DOL WH-380 series, Form WH-380-E for the employee's own condition and Form WH-380-F for a family member, which the employer requests and the employee returns. A PFML claim has no employer form at all: the employee files it directly with the DFML through paidleave.mass.gov.

What reaches the employer instead is a review request, and it runs on a clock. Per the DFML overview of PFML, the department notifies the employer within 5 days of the application being submitted, and the employer then has 10 business days to review it and supply information.

The DFML employer review process spells out what happens after that: if no leave administrator (the person an employer designates to handle these requests) responds in time, the department processes the application on the information it has. Employer questions go to the DFML contact center at (833) 344-7365.

Other Leave Requirements Beyond PFML

Massachusetts has a comprehensive set of leave requirements layered on top of PFML, including parental leave, which applies at the same six-employee threshold as Chapter 151B.

Parental leave

M.G.L. c. 149, § 105D requires employers with six or more employees to provide up to eight weeks of parental leave for the birth or the adoption or placement of a child. The leave may be paid or unpaid at the employer's discretion, and the statute has been gender-neutral since the 2014 amendment took effect in 2015.

Eligibility turns on the probationary period. An employee qualifies once they complete the employer's initial probationary period, which may not run longer than three months, or, where the employer sets none, once they have worked three consecutive months full time.

The employee gives at least two weeks of notice, or notice as soon as practicable when the delay is beyond their control. The leave runs concurrently with PFML and federal FMLA for qualifying events.

One limit catches two-parent households at the same company. Two employees of the same employer are entitled to eight weeks in aggregate for the birth or adoption of the same child, not eight weeks each.

Small Necessities Leave Act

Employers with 50 or more employees (using FMLA's 75-mile radius criterion) must provide 24 hours of unpaid leave per year under M.G.L. c. 149, § 52D. This leave is for school activities of a child, routine medical or dental appointments for a child, and accompanying an elderly relative age 60 or older to medical or dental appointments.

Employees may substitute accrued paid leave for this unpaid time. The leave comes in addition to FMLA entitlement, not out of it.

Jury duty pay

Massachusetts requires employers to pay regular wages for the first three days of jury service under M.G.L. c. 234A, § 48. After three days, the Commonwealth pays $50 per day, according to the Office of Jury Commissioner.

Full-time, part-time, temporary, and casual employees are all covered, with no size threshold. Retaliation for serving on a jury is prohibited under M.G.L. c. 268, § 14A.

Anti-Discrimination Under Chapter 151B

Chapter 151B is the primary Massachusetts anti-discrimination law, enforced by the Massachusetts Commission Against Discrimination. The agency's overview of the laws it enforces sets out the statutes and the protected categories behind everything in this section.

Pregnancy accommodation

The Pregnant Workers Fairness Act (effective April 1, 2018, M.G.L. c. 151B, § 4(1E)) requires employers to provide reasonable accommodations for pregnancy, childbirth, and related conditions unless doing so would cause undue hardship.

Four accommodations require no medical documentation at all: more frequent restroom, food, or water breaks, seating access, relief from lifting more than 20 pounds, and a private space for expressing milk that is not a bathroom. Requiring a doctor's note for any of those four is itself a violation.

Written notice runs on two triggers. Every new employee gets it at or before the start of employment, and any employee who tells the employer about a pregnancy or a related condition, lactation included, gets it not more than 10 days after that notification.

CROWN Act

Signed July 26, 2022 and effective October 24, 2022, the CROWN Act expands the definition of race under Chapter 151B to include traits historically associated with race: hair texture, hair type, hair length, and protective hairstyles. Protective hairstyles are defined to include braids, locks, twists, Bantu knots, and hair coverings. Policies that prohibit these hairstyles in the workplace constitute racial discrimination under Massachusetts law.

Remedies

MCAD remedies include back pay, front pay, emotional distress damages, and attorney fees. Cases removed to Superior Court can include punitive damages with no cap in Massachusetts. These remedies significantly exceed what federal Title VII caps allow.

The Commission can also assess a civil penalty on top of the award, and it escalates. Chapter 151B, § 5 sets it at up to $10,000 for a respondent with no prior adjudicated discriminatory practice, up to $25,000 for one prior within the preceding five years, and up to $50,000 for two or more within the preceding seven years.

Age discrimination cases carry their own multiplier: damages of not less than two and up to three times actual damages where the employer knew or had reason to know the practice was unlawful.

CORI, Ban-the-Box, and Background Check Compliance

Massachusetts has a comprehensive criminal record protection framework that applies to every stage of the hiring process and continues through employment.

The ban-the-box rule prohibits criminal history questions on the initial written application. Some records stay off limits at any stage of employment or hiring: arrests that produced no conviction, sealed or expunged records, juvenile records, and first convictions for certain minor offenses (drunkenness, simple assault, speeding, minor traffic violations, affray, disturbance of the peace).

Two different clocks run on the records that remain, and confusing them is the common error. What an employer may ask about is governed by Chapter 151B: a misdemeanor is off limits once three years have passed since the conviction or the end of any incarceration, absent another conviction inside that window.

What the report returns is governed by the DCJIS access level. Standard Access shows felony convictions for ten years and misdemeanor convictions for five, measured from the disposition or the release from incarceration.

Consumer reporting agencies sit under a third rule and may not report a criminal record that antedates the report by more than seven years under M.G.L. c. 93, § 52.

Before taking any adverse action based on criminal history, the Attorney General advises an individualized assessment of the offense, the time elapsed, and its relationship to the specific job, because blanket exclusions can violate civil rights laws. The applicant must receive a copy of their CORI report before any adverse decision.

Employers conducting five or more background checks per year must maintain a written CORI policy. The CORI system is accessed online through iCORI at a fee of $25 per name submitted.

Non-Compete Reform: The Massachusetts Noncompetition Agreement Act

The MNCA at M.G.L. c. 149, § 24L took effect October 1, 2018 and fundamentally changed how non-compete agreements work in Massachusetts. It introduced requirements found almost nowhere else in the country.

Garden leave is the most distinctive feature of Massachusetts non-compete law. Where an agreement relies on it, the former employer must pay the employee 50% of their highest annualized base salary within the two years preceding termination, on a pro-rata basis across the restricted period. The employer cannot unilaterally stop these payments except upon the employee's breach.

The statute also lets an employer substitute "other mutually-agreed upon consideration," and what that phrase will tolerate is still an open question.

Boyd v. The Boston Beer Company, a proposed class action filed in December 2025 in the U.S. District Court for the District of Massachusetts, argues that $3,000 against a one-year restriction falls far short of what garden leave would have cost. As of September 28, 2026, the public docket shows no ruling on Boston Beer's motion to dismiss, fully briefed on May 1, 2026, so there is no holding to rely on yet.

Non-solicitation agreements covering customers, clients, and fellow employees are entirely excluded from the MNCA and continue to be governed by common law reasonableness standards. The SJC confirmed this in Miele v. Foundation Medicine, Inc., 496 Mass. 171 (2025), decided June 13, 2025, which also held that a forfeiture clause triggered by breaching a non-solicitation covenant sits outside the Act. NDAs, confidentiality agreements, and invention assignment agreements are similarly unaffected.

Four categories of worker cannot be bound at all: employees classified as nonexempt under the FLSA, undergraduate and graduate student interns whether paid or unpaid, employees terminated without cause or laid off, and employees age 18 or younger. Specific professions are also barred from non-competes by separate statutes: physicians (M.G.L. c. 112, § 12X), nurses, psychologists, social workers, and broadcasting employees.

Workers' Compensation and Workplace Safety

Massachusetts requires workers' compensation coverage for virtually every employer and has a state plan under OSHA, the federal Occupational Safety and Health Administration, that applies only to public sector employers.

The Massachusetts workers compensation page has the detail: the headcount at which coverage becomes mandatory, who is excluded, where to buy the policy, the injury reporting deadlines, and what going without coverage costs.

Workers' compensation (M.G.L. c. 152)

All Massachusetts employers with one or more employees must carry workers' compensation insurance. Domestic workers employed for 16 or more hours per week are covered. Corporate officers owning 25% or more of the corporation may elect to exclude themselves using Form 153.

Injury reporting runs on a short deadline. Under M.G.L. c. 152, § 6, the First Report of Injury (Form 101) is due within 7 days, not counting Sundays and legal holidays, after the employer learns of an injury that keeps the employee from earning full wages for 5 or more calendar days.

Going uninsured is expensive in an unusual way. Per the Department of Industrial Accidents, a stop work order carries a minimum fine of $100 per day including weekends and holidays, rising to $250 per day if you appeal and stay open, and fines keep accruing until coverage starts and the fine is paid.

A criminal conviction adds up to one year of imprisonment and a fine of up to $1,500, and the business is barred from state and municipal contracts for three years.

OSHA coverage

Federal OSHA covers private sector employers in Massachusetts through area offices. According to the OSHA Massachusetts State Plan page, the state plan received initial approval on August 18, 2022 and covers all state and local government workers in the state, and nobody else.

The plan is administered by the Workplace Safety and Health Program of the Department of Labor Standards (DLS) under 454 CMR 25.00. Massachusetts is one of seven jurisdictions whose OSHA plan reaches state and local government workers only, alongside Connecticut, Illinois, Maine, New Jersey, New York, and the Virgin Islands. Private sector employers here deal with federal OSHA directly.

Required Workplace Postings

Massachusetts employers must display both state and federal required workplace posters. Every state poster is free, and the state poster requirements page lists which agency issues each one and links the current version.

Federal required postings include the FLSA Minimum Wage poster, EEOC Know Your Rights poster, federal OSHA Job Safety and Health poster, USERRA poster, and FMLA poster for employers with 50 or more employees. The PFML poster is updated annually; the 2026 version reflects the new maximum weekly benefit of $1,230.39.

Employee Privacy, Data Security, and Recording Rules

Massachusetts has three employee privacy rules that significantly exceed what most other states require: a felony recording consent standard, a mandatory written information security program for all employers, and a detailed personnel file access right.

All-party recording consent (M.G.L. c. 272, § 99)

Massachusetts prohibits secretly intercepting wire or oral communications. The key criterion is secrecy, not consent: if all parties to a conversation know that recording is occurring, it is lawful even if someone objects.

The penalties are why this rule gets its own section. Willful interception draws a fine of up to $10,000, or up to five years in state prison, or up to two and a half years in a house of correction.

The civil side adds a second bill. An aggrieved person recovers actual damages but never less than $1,000, or $100 for each day of violation, whichever is higher, plus punitive damages and attorney fees.

For employers, the practical rule is simple: no covert recording of calls, meetings, or conversations in any format. Security cameras running video only, with posted notices, are lawful. Any audio capture requires that everyone in the space knows it is happening.

Written Information Security Program (201 CMR 17.00)

Every person or organization that owns, licenses, stores, or maintains personally identifiable information of Massachusetts residents must have a comprehensive Written Information Security Program. This applies regardless of the employer's size, industry, or location. An out-of-state company with one Massachusetts employee is inside the rule.

Personal information has a specific definition in 201 CMR 17.02. It is a Massachusetts resident's first and last name, or first initial and last name, combined with a Social Security number, a driver's license or state ID number, or a financial account or credit or debit card number. Ordinary payroll files clear that bar on day one.

Required WISP elements include a designated security officer, a risk assessment, employee training, access controls, vendor management, encryption of portable devices, firewall protection, and an annual review. Penalties under M.G.L. c. 93A reach $5,000 per violation, plus private class action exposure.

Personnel file access (M.G.L. c. 149, § 52C)

Current and former employees may request access to their personnel file up to twice per calendar year, and a review triggered by negative information does not count against those two. Employers must provide the review, or a copy, within five business days of a written request.

Negative information carries its own notice duty. When an employer places something in the file that has been used, or may be used, to affect an employee's qualification for employment, promotion, transfer, extra compensation, or discipline, it must tell the employee within 10 days, and the employee may file a written rebuttal on any disputed item.

Retention is tied to headcount. An employer with 20 or more employees must retain personnel records complete and unexpunged from the date of employment until three years after termination, and longer where litigation is pending. Penalties range from $500 to $2,500 per violation, enforced by the Attorney General.

Termination and Separation

Massachusetts termination rules are among the most unforgiving in the country because of the Wage Act's automatic treble damages for final pay violations.

Final paycheck

Discharged employees must be paid in full on the day of discharge, including all earned wages, all accrued vacation, and commissions that are determined and due. For employees who quit, payment is due on the next regular payday, or the following Saturday if there is no regular payday.

Even one day late triggers mandatory treble damages, and corporate officers are personally liable. There is no exception for administrative delays, payroll system timing, or honest mistakes, so plan the final check before the termination meeting, not after it.

Health coverage continuation

Massachusetts mini-COBRA, the state version of federal COBRA health continuation coverage, applies under M.G.L. c. 176J, § 9 to employers with 2 to 19 employees for insured group health plans.

Mini-COBRA provides 18 months of continuation coverage for most qualifying events, 36 months for divorce or death of the covered employee, and up to 29 months where the beneficiary is determined disabled under Title II or Title XVI of the Social Security Act.

Mini-COBRA premiums have a ceiling. Per the Division of Insurance mini-COBRA guide, the premium is capped at 102% of the group rate, except that a disabled beneficiary may be charged 150% for the months after the 18th.

Two other continuation rules sit alongside it. M.G.L. c. 175, § 110G continues group health coverage for 39 weeks after an involuntary layoff or the death of the member, with no employer headcount threshold, and for 90 days after a plant closing or covered partial closing at a facility with 50 or more employees. Federal COBRA covers employers with 20 or more employees for 18 months as standard.

Massachusetts WARN provisions

Massachusetts does not have a comprehensive state WARN Act. Federal WARN, the Worker Adjustment and Retraining Notification Act at 29 U.S.C. §§ 2101-2109, applies to employers with 100 or more employees, requiring 60 days of notice for plant closings affecting 50 or more workers or mass layoffs of 50 or more workers representing at least one-third of the workforce, or 500 or more workers.

Two state provisions fill part of the gap. M.G.L. c. 149, § 179B requires an establishment employing 12 or more people to notify the Department of Career Services when it commences or changes the location of its operations in the Commonwealth.

The second is reemployment assistance under M.G.L. c. 151A, §§ 71A through 71G. Employees terminated by a plant closing or covered partial closing at a facility with 50 or more employees can draw up to 13 weeks of supplemental reemployment assistance benefits on top of regular unemployment.

Advance notice changes that number directly. Under section 71F, the 13 weeks are reduced week for week by any advance notification the employer gave and by any weeks of separation pay, so an employer that warns early or pays severance shortens the supplemental benefit period.

Payroll Tax and Registration Essentials

Running payroll in Massachusetts means registering with two separate state systems and folding the Millionaire's Tax surtax into withholding for higher-earning employees.

State income tax

Massachusetts imposes a 5.0% flat rate on wages, salaries, and other Part B income (the state's category for ordinary income) under M.G.L. c. 62. Per the Department of Revenue rate schedule, short-term capital gains are taxed at 8.5% and long-term collectibles at 12%.

The Millionaire's Tax sits on top of that. Approved by voters on November 8, 2022 and effective for tax years beginning on or after January 1, 2023, it adds a 4% surtax on taxable income above an annually indexed threshold, which is $1,107,750 for tax year 2026.

The effective top rate above the threshold is 9%. Employers fold the surtax into withholding using the 2026 Circular M withholding tables, which include the 4% surtax.

Withholding forms and registration

New employees in Massachusetts complete two withholding certificates, the federal W-4 and the state Form M-4. The M-4 is exemption-based and works differently from the redesigned federal W-4, because the 2017 federal tax act did not change how Massachusetts treats exemptions. If no M-4 is on file, the employer withholds on the basis of no exemptions.

Registration runs through two systems. Withholding, PFML contributions, sales tax, and corporate excise all sit in MassTaxConnect, the Department of Revenue portal described in the Department of Revenue guide to withholding taxes on wages. Unemployment insurance registration is separate and runs through the Department of Unemployment Assistance (DUA).

Unemployment Insurance

The Massachusetts UI taxable wage base is $15,000 per employee per year. According to the Department of Unemployment Assistance, the 2026 new employer rate is 2.42%, or 6.08% for new employers in the construction industry. Employers registered 3 or more years get an experience rate, which reflects their own unemployment account history and is calculated annually, with the rate notice issued by January 31.

The Employer Medical Assistance Contribution (EMAC) surcharge is the piece small employers miss. Per the DUA EMAC page, it does not apply in a quarter with fewer than 6 employees.

The EMAC rate phases in: nothing for the first 3 years of liability, 0.12% in year 4, 0.24% in year 5, and 0.34% from year 6, always on the first $15,000 of each employee's wages, so the ceiling is $51 per employee per year.

Coverage itself is triggered early. An employer becomes subject to UI when it pays $1,500 or more in wages in any calendar quarter, or has one or more employees for any portion of a day in each of 13 weeks in a year.

Boston and Local Requirements

Massachusetts cities and towns govern themselves under the Home Rule Amendment (Article 89 of the Amendments to the state constitution), within two limits that matter to employers. Section 6 allows a local ordinance only where it is not inconsistent with the constitution or state law. Section 7(5) withholds the power to enact private or civil law governing civil relationships, except as an incident to an exercise of an independent municipal power.

The minimum wage is set statewide under M.G.L. c. 151, § 1. Boston's Living Wage Ordinance is the closest thing to a local rate, and per the City of Boston labor compliance office, the rate is $19.36 per hour effective July 1, 2026, adjusted each July. It reaches workers on city service contracts and subcontracts worth at least $25,000, not private employers generally.

The Boston Residents Jobs Policy is similarly narrow. It is a construction hiring rule that reaches large development projects, and it has nothing to say about a typical office or retail payroll.

The practical upshot for most small businesses: the obligations in this guide come from state and federal law, and neither Boston rule above reaches a private employer without a city contract or a large construction project. A business in another city should still check that city's own ordinances, because section 6 leaves room for local rules that do not conflict with state law.

Massachusetts vs. Federal vs. New York

Massachusetts and New York are frequently compared as the two most employee-protective Northeast states. The table below shows where they diverge and where federal law provides the baseline.

Massachusetts stands apart from New York primarily in its all-party recording consent felony standard and its rule that every non-compete be backed by garden leave or other agreed consideration. Neither has a real counterpart in New York law.

Coverage runs the other way. The New York State Human Rights Law defines an employer as every employer in the state, with no headcount floor at all, since the four-person threshold was repealed effective February 8, 2020. New York also sets a higher minimum wage and reaches pay transparency at four employees against the Massachusetts threshold of 25.

Key Dates: Massachusetts Employment Law Timeline

Massachusetts has seen significant legislative activity since 2010, with the pace accelerating from 2018 through 2026. If your handbook, offer letters, or payroll settings were written before one of the dates below, check them against the rule that applies now.

Frequently Asked Questions

Does Massachusetts require E-Verify for private employers?

No. E-Verify is voluntary in Massachusetts, and no state statute or executive order requires private employers to use it. Executive Order 481 reaches only Executive Branch contractors, who certify they will not knowingly use undocumented workers, and it does not name E-Verify. Federal contractors carrying the FAR E-Verify clause must enroll regardless of state. Every employer must still complete federal Form I-9 for every new hire within 3 business days of the employee's first day of work.

How soon must I pay a terminated employee in Massachusetts?

When an employee is discharged, their final wages must be paid on the day of discharge under M.G.L. c. 149, § 148. When an employee quits, payment is due on the next regular payday, or on the following Saturday if there is none. Any violation triggers mandatory treble damages plus attorney fees. There is no good faith defense, and even a one-day delay after discharge is a violation.

Do small employers with fewer than 25 employees pay the PFML employer share?

No. Employers with fewer than 25 covered individuals are not required to pay the employer share of 0.42%. However, all employers regardless of size must withhold the employee share of 0.46% and remit it to the DFML. The combined rate for employers with 25 or more covered individuals is 0.88%. Small employers may voluntarily cover part or all of the employee share, but for 2026 that voluntary payment counts as wages on the employee's Form W-2.

Can I ask about criminal history on a job application in Massachusetts?

No. M.G.L. c. 151B, § 4(9½) prohibits any criminal history inquiry on the initial written application. Regardless of timing, you may never ask about arrests without conviction, sealed or expunged records, or first convictions for certain minor offenses. The applicant must get a copy of the record before any adverse decision, and the Attorney General recommends an individualized assessment first.

Is a non-solicitation agreement subject to the MNCA garden leave rule?

No. Non-solicitation covenants are explicitly excluded from the MNCA under § 24L(a) and are governed by common law standards of reasonableness. This was confirmed by the SJC in Miele v. Foundation Medicine, Inc., 496 Mass. 171 (2025). NDAs and confidentiality agreements are also excluded from MNCA requirements.

Do I need a Written Information Security Program (WISP)?

Yes, if you store personally identifiable information of Massachusetts residents. Under 201 CMR 17.00, the requirement reaches every employer, whatever its size or location, that keeps employee records pairing a name with a Social Security number, a driver's license or state ID number, or a financial account, credit card, or debit card number. Penalties reach $5,000 per violation under M.G.L. c. 93A.

Does the pay transparency law apply to my 20-person company?

The pay range disclosure requirement effective October 29, 2025 applies to employers with 25 or more employees. A 20-person company is not subject to the posting requirement. However, the salary history ban under M.G.L. c. 149, § 105A applies to all Massachusetts employers regardless of size: you cannot ask any applicant about prior salary before making an offer.
