Courts' treatment: partly invalid
A reviewed case holds part of this section invalid or unenforceable. In 1996 the Massachusetts Supreme Judicial Court held the then-current wording of § 4(1A) unconstitutional under the Establishment Clause. The Legislature amended that subsection in 1997 to protect sincerely held religious beliefs without regard to whether an established church requires them; the ruling concerns the earlier wording.
More on this status

In 2004 the court also held that applying the amendment retroactively to the employer in that case would violate due process.

This reflects what the reviewed cases said, not legislative action: a later amendment or repeal by the legislature would not appear here unless a reviewed case discussed it.

825 citing cases reviewed of 1,193 in the citation index: 565 interpreted the section (annotated below), 260 cited it only in passing. Cases filed after 2026-06-02 may not have been reviewed yet.

Employment coverage and exceptions

Section 4's expanded exemption for qualifying religious and affiliated organizations reaches protections against discrimination based on race, sex, and other listed traits as well as sexual orientation.

Collins v. Secretary of the Commonwealth · filed 1990-07-05

These amendments represent a broadening of the statutory exemption previously accorded religious institutions and organizations, and certain affiliated charitable or educational organizations, from the anti-discrimination provisions of c. 15IB. The exemptions they create are not limited to the new provisions of c. 15IB barring discrimination on the basis of sexual orientation, but extend to provisions barring discrimination on the basis of race, color, religious creed, national origin, sex, ancestry, age, or handicap.

Section 4(16A)'s prohibition on sexual harassment of employees does not cover volunteers because they are not employees under traditional common-law standards.

Lowery v. Klemm · filed 2005-04-21(16A)

In the same vein, a volunteer is not an employee under traditional common-law standards and, thus, would fall outside the protection for employees as codified in G. L. c. 151B.

Section 4(1B)'s age discrimination claim is unavailable against an employer with fewer than six employees.

Section 4(1) does not govern a discrimination claim by a shareholder who functions as an owner rather than an employee; status depends on the full relationship, not the label on an employment agreement.

Theroux v. Stephen Singer, DDS, PC · filed 2006-04-20(1)

Taking all these factors into consideration, Dr. The-roux appears to have been an employer not an employee of BVDA for the purposes of c. 15 IB. ... Having found that Dr. Theroux was not an employee of BVDA, it follows that she is not subject to the requirements of c. 15 IB.

Section 4 is preempted by ERISA when applied to the discrimination claims concerning an ERISA benefit plan in this case, but remains applicable to non-ERISA benefits.

Partners Healthcare System, Inc. v. Sullivan · filed 2007-06-25

Having found the state law broader than the federal law, and finding no meaningful factual dispute, the court holds application of M.G.L. ch. 151B § 4 to the Plaintiffs ERISA plans in the MCAD proceedings on Defendant Webster’s charge to be facially conclusively preempted by ERISA.

Section 4 does not support a claim by someone who is neither a current nor a prospective employee of the defendant.

Doe v. Harvard University · filed 2019-10-17

Second, plaintiff lacks standing to assert a claim under M.G.L. c. 151B, the Fair Employment Practices Act, because she is not a current or prospective employee of Harvard. Mass. Gen.

Section 4(2) prohibits discrimination by labor organizations and does not apply to a claim that an employer discharged an employee because of race.

Sweeney v. Santander Bank, N.A. · filed 2021-09-16(2)

Section 4(2) prohibits discrimination by labor organizations, and § 2 states a special commission will make policy recommendations relating to Chapter 151B.

Section 4(16) protects an employee’s discrimination claim independently of a collective bargaining agreement, so the claim is not preempted by § 301 of the Labor Management Relations Act.

Cullen v. Henry Haywood Memorial Hospital · filed 2015-03-26(16)

While the reference to the promotion and termination provisions of the CBA may be relevant to the analysis of this claim, resolution of the discrimination claim does not in any way “depend” on interpretation of the CBA. The rights guaranteed to the Plaintiff by Chapter 151B exist independent of the CBA; and as such, the principles mandating preemption under § 301 are inapplicable here.

Sexual orientation discrimination

Law changed since 1989 Mass. Acts ch. 516, § 4 (approved Nov. 15, 1989) added sexual orientation to the protected grounds in § 4(1); this earlier exclusion no longer governs.

Section 4(1)'s prohibition on employment discrimination because of sex does not cover discrimination based on an employee's sexual preference.

MacAuley v. MASSACHUSETTS COMM. AGAINST DISCRIMINATION · filed 1979-11-29(1)

Employer and supervisor liability

Section 4(5) prohibits an employer from aiding or abetting discriminatory acts by its own employees.

Walters v. President & Fellows of Harvard College · filed 1985-08-15(5)

Clearly, the statute draws a distinction between an employer and its employees, i.e., the statute does not consider them to be a single entity. Thus, a straightforward reading of the statute leads to the conclusion that an employer can aid or abet its own employees.

General Laws c. 151B, §4(5) states that it is unlawful for “any person, whether an employer or an employee ... to aid, abet, incite, compel or coerce the doing of any acts forbidden under this chapter or to attempt to do so.” ... I agree with the reasoning of those decisions, and conclude, therefore, that the individual defendants may be sued individually for aiding and abetting the defendant corporation Perico. ...

Section 4(5) permits personal liability for coercing or compelling acts forbidden by chapter 151B, as well as for aiding and abetting them.

Beaupre v. Cliff Smith & Associates · filed 2000-11-16(5)

The defendants’ focus on the aiding and abetting provision of § 4(5) is, moreover, unduly narrow. When instructing the jury that they were to confine their liability deliberations to whether Smith’s alleged conduct amounted to sexual harassment as defined in c. 151B, § 1(18), and, if so, whether that conduct fell within § 4(5), the judge did not confine their consideration of Smith’s personal liability to whether his conduct constituted aiding and abetting.

Newell v. Celadon Security Services, Inc. · filed 2006-01-17(16A)

When co-workers, rather than supervisors, are the perpetrators of sexual harassment, both Title VII and Mass. Gen. Laws ch. 151B apply the same standard in assessing employer liability. ... Similarly, under [C]hapter 151B, employer liability for coworker harassment requires a showing that the employer knew or should have known about the harassment, yet failed to halt it.” ... The record also fails to establish that Celadon is liable under the lesser standard applied to co-worker harassment.

Downey v. Earl Johnson and Massachusetts Department of State Police · filed 2021-10-08(5)

To the extent Downey seeks to assign liability to Johnson individually for retaliation, she can only do so under a theory of “aiding and abetting.” See G.L. c. 151B, § 4(5) (making it unlawful for “any person, whether an employer or an employee or not, to aid [or] abet . . . the doing of any of the acts forbidden under [G.

Section 4(16) requires proof of injury caused by an unlawful preemployment disability inquiry to recover damages, assuming a private claim is available.

Martino v. Forward Air, Inc. · filed 2010-06-14(16)

But here we need not decide whether there is indeed a cause of action under the Massachusetts statute because, even assuming such a claim were permitted, there is no doubt that a plaintiff would need to show proof of injury caused by the illegal questioning in order to recover damages.

Section 4(16) permits an employer to require medical or psychological testing after an offer of employment, but not before one.

Police Department of Boston v. Kavaleski · filed 2012-11-06(16)

To comport with the requirements of the Massachusetts antidiscrimination law, G. L. c. 151B, § 4 (16), and provisions of the Americans with Disabilities Act, 42 U.S.C. § 12112(d) (2006), an employer may not conduct medical or psychological testing prior to making an offer of employment, but may condition an offer of employment on the successful completion of such testing.

Section 4(16) prohibits preemployment inquiries about an applicant’s handicap; an innocuous exchange about possible accommodations does not qualify.

Felix v. Town of Kingston · filed 2019-07-08(16)

In the court’s view, this exchange was innocuous and does not rise to the level of a preemployment inquiry within the meaning of the statute.

Section 4(16) prohibits preemployment inquiries about an applicant’s disability, but a request for possible accommodations in this context was not such an inquiry.

Felix v. Town of Kingston · filed 2021-12-23(16)

Therefore, as the magistrate judge noted, this inquiry, when viewed in context, is not the type of pre-employment inquiry contemplated by Mass. Gen. Laws. ch. 151B § 4(16).10 We agree -- so we decline to consider it further.

Handicap discrimination and accommodation

Section 4(16) does not require an employer to excuse an employee from an essential job function as a reasonable accommodation.

Cox v. New England Telephone & Telegraph Co. · filed 1993-02-24(16)

As we have said earlier in this opinion, the Federal law is clear, and there is no reason to construe the Commonwealth's law differently, that reasonable accommodation does not include waiving or excusing an inability to perform an essential job function.

Section 4(16) does not require an employer to give an employee additional time to prove he can perform essential job functions when doing so would impose an undue burden.

Perkins v. Flatley · filed 1993-09-30(16)

Reasonable accommodation in this case did not require the Flatley Company to provide plaintiff with additional time within which to prove that he was capable of performing the essential functions of a “house person.” This would have imposed an undue burden on the employer.

Section 4(16) does not require an employer to depart from a bona fide seniority system to accommodate a handicap when the system is not a subterfuge to evade the law.

Buckley v. Department of Mental Health · filed 1994-03-21(16)

Plaintiff fails to assert or introduce evidence demonstrating that the seniority system was not bona fide or a subterfuge designed to evade the law. Thus, by following the dictates of a bona fide seniority system, DMH cannot be found to violate Buckley’s rights under G.L.c. 15 IB, §4(16).

Section 4(16) requires a handicap discrimination claimant to show that he can perform the job’s essential functions with reasonable accommodation; a genuine dispute about those functions prevents summary judgment.

Rice v. M/A-Com, Inc. · filed 1993-10-07(16)

The party claiming handicap discrimination under G.L.c. 151B, §4(16) must be able to establish the following: he is handicapped: he is a “qualified handicapped person”: and he is capable of performing the essential functions of his position with reasonable accommodation at the time the discrimination occurred. ... Because there is still a dispute as to the essential functions of the stockroom job, hindering a determination of Mr. Rice’s status as a handicapped person, summary judgment for Count I is denied.

Section 4 governs employment discrimination against a qualified handicapped person, including one whose work-related injury qualifies under chapter 152, §75B(1).

Belonni v. Reservoir Nursing Center · filed 1994-01-18

While arguably the term “this section” applies to all of §75B and not just §75B(2), §75B(1) is simply definitional and adds certain work-related injuries to the roster of handicaps otherwise defined in c. 15 IB, §§1(16), 1(17). An employer who impermissibly deals with a handicapped person thus violates c. 151B, §4, not c. 152, §75B and the former statute’s remedial scheme therefore controls.

A disability benefits application does not conclusively establish that an employee is unqualified under § 4(16) when the employee states that reasonable accommodation would have enabled him to perform his job.

Ward v. Westvaco Corp. · filed 1994-07-06(16)

Ward’s clear and deliberate qualification of his handicap status in his application for disability benefits takes his case outside the framework of August. ... Here, disputed issues exist as to whether Ward was a “qualified handicapped person.”

Section 4(16) protects employees with known heart disease who can perform their jobs from discharge solely because of their condition.

Talbert Trading Co. v. Massachusetts Commission Against Discrimination · filed 1994-07-22(16)

We conclude that persons suffering from heart disease or other cardiac conditions known to their employers at the time of hiring and who are otherwise able to perform their work, are protected by the statute from discharge solely on account of their heart condition.

Section 4(16) requires a person claiming handicap discrimination to be capable of performing the job’s essential functions with reasonable accommodation.

Beal v. Board of Selectmen · filed 1995-02-21(16)

Because police officers are responsible for public safety, and the plaintiff’s handicap severely compromises her capability to ensure the general safety of the public, we think that there are no reasonable accommodations that would enable the plaintiff to perform the essential functions of a police officer. The plaintiff, therefore, has no reasonable expectation of demonstrating that she is a qualified handicapped person under either G. L. c. 15IB or § 504 of the Rehabilitation Act.

Section 4(16) limits its prohibition on otherwise discriminating because of handicap to decisions affecting employment status; a supervisor’s isolated instruction that causes an injury does not itself state a claim.

Smedley v. Everett Management Corp. · filed 1995-07-14(16)

The specific terms in Section 4(16) have in common that they are decisions relating to employment status.

Section 4 requires an employee claiming handicap discrimination to be qualified for the position from which they were discharged, with or without reasonable accommodation.

Reidy v. Travelers Insurance · filed 1996-06-03

Because plaintiff in this case admits that he could not perform any of the functions of a claims representative, regardless of accommodation, the Court concludes that plaintiff has faffed to show that he was “qualified” for the position from which he was discharged.

Section 4(16) requires consideration of accommodations that would enable a handicapped employee to perform essential job functions, but does not require an employer to waive those functions.

Picot v. New England Telephone & Telegraph Co. · filed 1994-12-15(16)

Section 4(16) of c. 151B provides that where a handicapped person is unable to perform essential job functions courts must consider whether any reasonable accommodation by the employer would have enabled the person to perform. However, Coxmakes clear that reasonable accommodation does not require an employer to disregard or waive an employee’s inability to perform an essential function of the job.

Section 4(16)’s reasonable accommodation inquiry applies when a handicapped employee cannot perform the essential functions of the job.

Tate v. Department of Mental Health · filed 1995-01-24(16)

Although the plaintiff argues on appeal that there is a factual issue whether the Association reasonably accommodated her handicap, this issue is only considered when a handicapped person is not able to perform the essential functions of the job.

Section 4(16) requires reasonable accommodation for a qualified handicapped employee; whether working from home is reasonable may depend on the employee’s job duties and the available arrangements.

Mason v. Pegasystems, Inc. · filed 1996-06-10(16)

Such a determination, however, is more appropriately determined by the trier of fact as the summary judgment record is replete with numerous issues of material fact. For example, issues of material fact are presented as to what functions Mason’s job consisted of, and whether reasonable accommodations, such as sending in her assignments via a home computer and modem, were plausible.

Section 4(16) requires a plaintiff alleging disparate treatment based on a handicap to produce some evidence that he was handicapped, qualified for an open position, rejected despite his qualifications, and that the employer continued seeking applicants.

Whalen v. Nynex Information Resources Co. · filed 1995-03-28(16)

To establish a prima facie case of “disparate treatment” on the basis of a handicap, a plaintiff must produce some evidence that: (1) he is handicapped; (2) he is a qualified handicapped person and he applied for a position for which the employer was seeking applicants; (3) the employer rejected the plaintiff for the position in spite of his qualifications; (4) after the employer rejected the plaintiff, the position remained open and the employer continued to seek applicants.

Section 4(16) protects an employee whom the employer perceives as handicapped, even if the employee disputes having a handicap.

Lee v. Massachusetts Bay Transportation Authority · filed 1995-08-08(16)

The MBTA relies on the fact that Lee himself argues that he is not handicapped. I find, however, that Lee is a member of the class of handicapped individuals protected by G.L.c. 151B, §4(16) because he is perceived by his employer as handicapped.

Section 4(16) allows a handicap discrimination claim by a worker who can perform essential job functions with reasonable accommodation; that ability does not rule out handicap status.

Stoupakis v. Midas International Corp. · filed 1995-12-19(16)

If ability to work were, by itself, sufficient to take a plaintiff outside the definition of “handicapped,” there could never be a viable claim of handicap discrimination in employment. Defendants’ argument would lead to the absurd result that in proving that a plaintiff was “capable of performing the essential functions of the position involved with reasonable accommodation,” G.L.c. 15 IB, §4(16), every plaintiff would simultaneously be proving that he was not “handicapped.” This is obviously not what the statute means.

A person who seeks disability benefits after termination is not automatically estopped from bringing a handicap discrimination claim under § 4 when evidence shows that reasonable accommodation could have enabled the person to perform the job.

Labonte v. Hutchins & Wheeler · filed 1997-05-05

Section 4(16) prohibits an employer from refusing to hire a qualified person because of a handicap when the person can perform the job’s essential functions with reasonable accommodation that does not impose an undue hardship.

Broadway Brake Supply, Inc. v. Massachusetts Commission Against Discrimination · filed 1997-06-12(16)

Malone established a prima facie case that he was a qualified individual who was rejected on the basis of his handicap. Because Broadway failed to show that it refused to hire Malone for reasons other than his handicap, the Decision and Order of the Full Commission holding that Broadway discriminated against Malone is AFFIRMED.

Section 4(16) permits an employer to require medical examinations of an employee seeking re-employment after disability retirement to assess fitness for the job.

White v. City of Boston · filed 1997-07-22(16)

Because the ADA, the Rehabilitation Act, and c. 15 IB do not specifically prohibit medical examinations for persons applying for re-employment, and because case law supports examinations in these circumstances, this court finds that the City did not violate the ADA, the Rehabilitation Act, or c. 151B when it required White to submit to the exams.

Pregnancy complications that substantially limit daily activities can qualify as a handicap for a § 4(16) discrimination claim.

Sbrogna v. ChipCom Corp. · filed 1997-09-30(16)

Because Sbrogna was limited in her ability to conduct her daily activities due to her pregnancy complications, it cannot be said that her pregnancy was not a physical impairment which substantially limited one or more major life activity.

Section 4(16) did not require an employer that had already granted leave for substance abuse treatment to grant a second leave for alcoholism in these circumstances.

Evans v. Federal Express Corporation · filed 1998-01-09(16)

We need not resolve such issues in this case because we agree with the district court’s final ground for summary judgment, namely, that the company was not obliged to give Evans a second leave of absence for substance abuse. Evans had already been given a month’s leave to deal with cocaine addiction. His present claim rests on the view that in his circumstances a second leave to treat alcoholism was an obligatory reasonable accommodation. The district court said it was not, and we agree.
