Retaliation
Section 4(4) prohibits retaliation for opposing discrimination and requires a retaliation claimant to show protected activity, an adverse employment action, and a causal link between them.
Collison v. Sun Microsystems, Inc. · filed 2004-11-05(4)
Under G.L.c. 151B, §4(4), it is unlawful for an employee to discriminate against any person who has filed a complaint or opposed any practice forbidden by the discrimination statute. In order to survive summary judgment on the retaliation claim, Ms. Collison must provide evidence satisfying the following three elements: 1) that the plaintiff engaged in a protected activity; 2) that the plaintiff suffered an adverse employment action; and 3) that there is a causal link between the protected activity and the employment action.Read the full opinion on CourtListener →
Section 4(4) protects an employee’s complaint about suspected discrimination, but a retaliation claim requires a causal connection between that complaint and an adverse employment action.
Ahanon v. Cerebral Palsy of Massachusetts · filed 2005-01-31(4)
Assuming this meeting took place as described by the plaintiff, this activity would be sufficient to activate the protection of c. 151B, §4(4). ... The court finds that the causal nexus is too attenuated for the plaintiff to sustain a claim of retaliation.Read the full opinion on CourtListener →
Section 4(4) protects an employee who supports a spouse’s sexual harassment complaint from retaliation by the employer.
Mole v. University of Massachusetts · filed 2003-05-08(4)
General Laws c. 151B, § 4(4), inserted by St. 1946, c. 368, § 4, declares that it is an unlawful practice for an employer “to discharge, expel or otherwise discriminate against any person because he has opposed any practices forbidden under this chapter.” The plaintiff’s support of his wife’s sexual harassment complaint was a protected activity, thereby satisfying the first requirement of a prima facie case.Read the full opinion on CourtListener →
Section 4(4A) protects the exercise of rights under chapter 151B; seeking workers’ compensation benefits under chapter 152 does not qualify.
Courtois v. Legal Seafoods, Inc. · filed 2004-02-06(4A)
The plaintiffs retaliation claim invokes G.L.c. 151B, §4.4A. That statute provides, in pertinent part, that it is unlawful “for any person to coerce, intimidate or threaten to interfere with another person in the exercise or enjoyment of any right granted or protected by this chapter.” The complaint alleges, without specificity, that the plaintiff “exercised statutory rights permitted and protected under G.L.c. 151B.” The record presented on this motion does not identify any conduct of the plaintiff in the exercise of such rights prior to his termination. Indeed, there is nothing whatever in the record to indicate that the plaintiff ever invoked any rights under c. 151B, or engaged in any conduct protected under that statute, prior to his termination.Read the full opinion on CourtListener →
Section 4(4) does not protect complaints about discrimination based on patients’ ability to pay for medical care or an employee’s status as a single mother.
Martinez v. New England Medical Center Hospitals, Inc. · filed 2004-03-03(4)
Neither of these actions constitutes a protected activity under Title VII or chapter 151B § 4(4).Read the full opinion on CourtListener →
Section 4(4) and (4A) prohibit a supervisor from recommending an employee’s termination in retaliation for filing an MCAD complaint.
Williams v. Massachusetts Housing Finance Agency · filed 2003-09-17(4), (4A)
In finding that defendant Connolly engaged in unlawful retaliation, the jury necessarily found that Connolly, motivated by a retaliatory animus, recommended that plaintiff be terminated because he had filed an MCAD complaint. That is clearly conduct prohibited by G.L.c. 151B, §4(4) and (4A).Read the full opinion on CourtListener →
Section 4 permits a retaliation claim even when the employee fails to establish a disability discrimination claim.
Wright v. Comp USA, Inc. · filed 2003-12-22
Massachusetts's anti-discrimination law also treats retaliation as a "separate and independent cause of action." ... Wright's failure to establish a disability does not preclude his retaliation claim.Read the full opinion on CourtListener →
Section 4(4) and (4A) do not permit an inference of retaliation from later adverse actions when the employee’s problems began before the employer knew of the protected activity.
Mole v. University of Massachusetts · filed 2004-09-01(4) and (4A)
Where, as here, adverse employment actions or other problems with an employee predate any knowledge that the employee has engaged in protected activity, it is not permissible to draw the inference that subsequent adverse actions, taken after the employer acquires such knowledge, are motivated by retaliation.Read the full opinion on CourtListener →
Filing a discrimination charge is protected activity under § 4(4), but the filing may still be unreasonable for purposes of proving retaliation.
Pardo v. General Hospital Corp. · filed 2006-01-26(4)
Although the filing of a charge of discrimination is a “protected” activity under G. L. c. 151B, § 4 (4), it may not be “reasonable” for purposes of proving retaliation.Read the full opinion on CourtListener →
Section 4(4) requires a retaliation claimant to show a causal link between protected activity and an adverse employment action.
Douglas v. JC Penney Co., Inc. · filed 2006-03-30(4)

Section 4(4) covers an employer’s refusal to renew an appointment in retaliation for an employee’s gender discrimination lawsuit.
Ayash v. Dana-Farber Cancer Institute · filed 2005-02-09(4)
Based on the facts set forth in part l.d of this opinion, a reasonable jury could conclude that Dana-Farber’s decision not to renew the plaintiff’s appointment was motivated by retaliatory animus fueled by the plaintiff’s filing of a lawsuit against Dana-Farber alleging discrimination based on gender.Read the full opinion on CourtListener →
Section 4(4) treats a hostile work environment imposed in retaliation for protected activity as an adverse employment action.
Noviello v. City of Boston · filed 2005-02-16(4)
For the reasons elucidated above, we hold that, under Massachusetts law as under Title VII, subjecting an employee to a hostile work environment in retaliation for protected activity constitutes an adverse employment action (and, thus, triggers the statutory prophylaxis).Read the full opinion on CourtListener →
Section 4(16A) requires sexual harassment to create a hostile, intimidating, or abusive work environment that affects the employee’s work; a vague, isolated suggestion is insufficient.
Mireault v. Northeast Motel Associates, LP · filed 2006-02-02(16A)
In Massachusetts, employers are prohibited from discriminating against their employees on the basis of sexual harassment pursuant to G.L.c. 151B, §4(16A). ... Assuming Tucker made the comment, it is too vague, ambiguous and innocuous to connote sexual harassment.Read the full opinion on CourtListener →
Section 4 permits significant harassment outside work to be considered when assessing whether a work environment is hostile.

Section 4(4) does not protect an employee from retaliation for objecting to another employee’s promotion unless the objection is based on a claim of discrimination.
Montlouis v. Pirus Networks, Inc. · filed 2005-03-15(4)
There is no cause of action under G.L.c. 15IB for retaliating against an employee for objecting to someone else’s promotion when that objection is not based on a claim of discrimination.Read the full opinion on CourtListener →
Section 4(4) permits a retaliation claim when retaliatory harassment creates a hostile work environment.
Gerrie v. Karl Storz Endovision, Inc. · filed 2005-12-29(4)
In recent years, the definition of the “adverse employment action” element of a retaliation claim under 15 IB has been expanded to include a retaliatory hostile work environment.Read the full opinion on CourtListener →
Section 4(4) prohibits retaliation for testifying in a discrimination proceeding; a claim requires protected activity, an adverse employment consequence, and causation.
Ciccarelli v. School Department of Lowell · filed 2007-12-07(4)
An employer may not “discharge, expel or otherwise discriminate against any person . . . because he has filed a complaint, testified or assisted in any proceeding under section five.” G. L. c. 151B, § 4(4), inserted by St. 1946, c. 368, § 4. A retaliation claim under c. 151B must fulfill three elements: (1) the employee engaged in a protected activity; (2) the employee faced an adverse employment consequence; and (3) the protected activity caused the adverse employment action.Read the full opinion on CourtListener →
Section 4(4) requires a causal link between protected conduct and an adverse employment action; an earlier termination decision does not establish retaliation without evidence of a later adverse action.
Rhodes v. JPMorgan Chase & Co. · filed 2008-06-24(4)
The adverse action alleged by Rhodes is the job elimination/termination letter of June 17, 2005. The earliest instance of arguably “protected conduct” by Rhodes occurred on July 20, 2005, when her lawyer sent a demand letter to JPMSI’s general counsel. The offer by JPMSI of a transfer to Beinstein’s group, which was made in mid-June (before the demand letter was sent), remained open to at least August 8, 2005. Rhodes offers no evidence that JPMSI withdrew or suspended the offer after receiving the demand letter.Read the full opinion on CourtListener →
Section 4(4) requires a retaliation plaintiff to show that the employer knew of the protected conduct before taking adverse action.
Navarro v. U.S. Tsubaki, Inc. · filed 2008-09-17(4)
If the defendant did not know that the plaintiff undertook conduct that was protected, then any subsequent adverse employment action cannot be linked to the protected conduct.Read the full opinion on CourtListener →
Sections 4(4) and 4(4A) require a retaliation plaintiff to show protected conduct, an adverse action, and a causal connection between them.
Bolduc v. Town of Webster · filed 2009-05-22(4), (4A)
To maintain a claim of retaliation under sections 4(4) and 4(4A), the plaintiff has the burden of establishing (1) that he engaged in protected conduct; (2) that he suffered adverse action; and (3) that a causal connection existed between the protected conduct and the adverse action.Read the full opinion on CourtListener →
Section 4(4) requires a person claiming retaliation to show an adverse employment action, even when the alleged retaliation is a lawsuit.
Visnick v. Marriott International, Inc. · filed 2007-08-06(4)
However, even with a lawsuit filed against an employee, to make out a claim for retaliation pursuant to G.L.c. 151B, §4(4), the employee must still show she suffered an adverse employment action.Read the full opinion on CourtListener →
Section 4(1) permits a gender discrimination claim when denying employees a rank-specific locker room could deprive them of a material condition or privilege of employment.
King v. City of Boston · filed 2008-03-28(1)
Here, the plaintiffs have presented evidence that the denial of a rank-specific locker facility deprives them of a material feature of their employment. While such a finding may not be compelled, it would be permissible and thus precludes summary judgment on the issue.Read the full opinion on CourtListener →
Section 4(16) treats removal from the work schedule and an offer of substantially reduced pay and hours as materially adverse employment actions.
Sensing v. Outback Steakhouse of Florida, LLC · filed 2009-08-11(16)
The record establishes that appellees removed Sensing from the work schedule after she missed only one and a half covered shifts, offering her in the alternative a "light duty" position with substantially reduced salary, hours and responsibilities. These actions disadvantaged Sensing with respect to the terms and conditions of her employment, see MacCormack, 672 N.E.2d at 8, and amounted to far more than mere trivial inconveniences.Read the full opinion on CourtListener →
Section 4 may treat a policy requiring teachers to submit to searches of their persons and vehicles as an adverse employment action if it disadvantages their employment conditions.
Lucien v. Conlee · filed 2009-09-03
Because a new policy (particularly one not approved by the teachers’ union) requiring that teachers submit to searches of their persons and vehicles prior to leaving school property could be considered a disadvantageous change in employment conditions, a genuine issue of material fact exists as to whether Lucien was subjected to an adverse employment action.Read the full opinion on CourtListener →
A workplace complaint is protected against retaliation under Section 4 when it challenges an employment practice prohibited by Chapter 151B.
Walker v. City of Holyoke · filed 2007-11-30(4)
However, the court need not consider this as possible evidence of retaliation under Title VII or Chapter 151B since the dispatching complaint was not a protected activity. Walker did not assert at the time that she was challenging an employment practice prohibited by either statute.Read the full opinion on CourtListener →
Section 4(4) protects opposition to practices forbidden by Chapter 151B; complaints about alleged financial-law violations do not qualify.
Fantini v. Salem State College · filed 2009-02-23(4)
Again we find that Fantini did not comply with the first prong by failing to show that she engaged in a protected activity, since the “misconduct of male, Edward Manning under the (“Conflict of Interest Law and Financial Disclosure Law”) ...; for changing the general ledger system contrary to law,” does not constitute a forbidden practice under the Massachusetts anti-discrimination statute, M.G.L.A. ch. 151B § 4.Read the full opinion on CourtListener →
Section 4(4) protects an employee who requests an accommodation for a disability from retaliation, even if the employee never files a formal complaint.
Gauthier v. Sunhealth Specialty Services, Inc. · filed 2008-03-27(4)

Section 4(4) and (4A) allow retaliation claims based on acts that occur after employment ends; the timing alone does not bar the claims.
Ngassa v. Ocean State Job Lot Stores of SE MA, Inc. · filed 2010-02-03(4), (4A)
I find that the acts complained of in the instant action, ie. post-termination retaliation, state claims under G.L.c. 151B, §§4(4) and 4(4A). Having found that the post-termination nature of the alleged retaliatory acts do not present a legal bar, the plaintiffs complaint must be examined to determine whether such counts set forth allegations which, when read most favorably for plaintiff, plausibly suggest plaintiffs entitlement to relief.Read the full opinion on CourtListener →
Section 4(4) permits a retaliation claim when an employer places an employee in a job he cannot perform because he complained of racial discrimination, causing constructive discharge.
Green v. Harvard Vanguard Medical Associates, Inc. · filed 2011-03-03(4)
Given the evidence in the summary judgment record, there is a genuine issue of material fact whether Green was intentionally recommended for (and subsequently hired into) a job for which he was not qualified and from which he was consequently bound to separate such that his resignation from that position amounted to constructive discharge — an adverse employment consequence — and whether Harvard Vanguard’s decision to take this course of action was a result of his having complained about his supervisor’s alleged racially discriminatory conduct.Read the full opinion on CourtListener →
Section 4(4) protects requests for disability accommodations from retaliation, but a claim requires evidence that retaliatory animus motivated the adverse employment action.
Cyr v. United Parcel Service, Inc. · filed 2011-06-16(4)
Plaintiff has alleged that Defendant retaliated against her in violation of 42 U.S.C. § 2000e-3 and Mass. Gen. Laws ch. 151B, § 4(4). ... Without passing judgment on the propriety of Defendant’s conduct, the court cannot identify a single fact tending to show that Defendant harbored any animus toward Plaintiff based on her invocation of her rights under the ADA. ... Thus, Defendant’s motion for summary judgment on Plaintiffs retaliation claims, Counts III and VI, will be allowed.Read the full opinion on CourtListener →
A retaliation claimant under § 4(4) need not prove actual discrimination, but must reasonably and in good faith have believed that unlawful discrimination occurred.
Cánovas v. University of Massachusetts Medical School · filed 2011-12-08(4)

Section 4(4) permits a retaliation claim to proceed when evidence links disability leave to an adverse evaluation and creates a factual dispute over the employer’s reason for discharge.
Haraden v. Verizon New England, Inc. · filed 2012-06-05(4)
Prouty’s allegedly discriminatory evaluation and animus occurred in the immediate aftermath (in fact, during) the plaintiffs disability leave. This supports an inference of causation. There is a genuine issue of material fact as to whether Verizon’s business reason for discharging Haraden in part as a result of that retaliatory evaluation was a pretext for retaliation.Read the full opinion on CourtListener →

Dias v. Verizon New England, Inc. · filed 2014-06-05
Here, even assuming that the October 2007 e-mail was activity protected under a state law, it is clear that no rational, properly instructed jury could find that Verizon fired Dias in retaliation for sending it. ...

The Court concludes, even assuming that Plaintiff has plausibly alleged that he participated in oppositional conduct—which is questionable—and was subject to an adverse employment action, the claim nonetheless fails because the amended complaint does not plausibly allege a connection between his negative performance review and the race-based concerns he shared with supervisors.Read the full opinion on CourtListener →
Section 4 retaliation claims require protected conduct, an adverse action, and a causal connection between them.
Boykin v. Genzyme Therapeutic Products · filed 2023-07-12(4)

Section 4(4) prohibits retaliation for filing an MCAD charge, but a denied promotion fourteen months later, without other evidence of discriminatory treatment, does not establish causation.
Knightly v. Town of Amherst. · filed 2023-04-21(4)

Ferrie v. Department of Correction. · filed 2023-10-19(4)
As detailed supra, and taken in the light most favorable to Ferrie, the record supports an inference that, at a minimum, Ferrie complained about a sergeant's allegedly-retaliatory behavior to a captain, and was promised that it would be dealt with.

Section 4(4) requires a retaliation plaintiff to plausibly link protected conduct to an adverse employment action.
Robert v. Raytheon Technologies Corporation · filed 2024-04-25(4)

Where Baker plausibly alleges that the choices he faced upon Majenski's return to Troop D headquarters were all "totally unacceptable" and, as a result, "a reasonable person in [Baker's] shoes would have felt compelled to resign," it was improper to dismiss his retaliation claim on the ground that he failed to plead an adverse employment action.Read the full opinion on CourtListener →

Section 4(4A) prohibits retaliation, and the state-law claim follows the Title VII claim for purposes of this appeal.
Billings v. Town of Grafton · filed 2008-02-07(4A)
Massachusetts law contains a similar prohibition, Mass. Gen. Laws ch. 151B, § 4(4A), and, as with the hostile environment claim, neither side argues that the standards of liability for a retaliation claim under federal and state law differ in any respect material to the outcome here. Accordingly, we do not separately consider the state-law retaliation claim which, like the state-law hostile environment claim, rises or falls on the federal claim for purposes of this appeal.Read the full opinion on CourtListener →
Section 4(4) prohibits retaliation for discrimination complaints; obligatory counseling can qualify as an adverse action when its consequences could dissuade a reasonable worker from complaining and it was prompted by a retaliatory motive.

Massachusetts has a counterpart provision. Mass. Gen. Laws ch. 151B, § 4(4) (2011). ... Obligatory counseling is not a typical adverse action but the impact here could be deemed sufficient by the jury if the action was prompted by a retaliatory motive.Read the full opinion on CourtListener →
Section 4 prohibits retaliation and coercion against a person for filing a discrimination complaint; using a judgment levy to pressure that person to drop the complaint is unlawful when the levy is not a bona fide collection attempt.

We conclude that, even if there is a constitutional right to levy on a writ of execution -- a question we do not decide -- it does not extend to abuse of the levying process to extort a person to drop a discrimination claim. ... Based on the hearing officer's findings, the employer's actions in using the seizure of the minivan to pressure Shanahan to drop his discrimination claim were not a bona fide attempt to collect on the judgment and thus were constitutionally unprotected.

Disparate impact and age discrimination

William MULLIN, Plaintiff, Appellant, v. RAYTHEON COMPANY, Defendant, Appellee · filed 1999-01-13(1B)
Under these circumstances, we conclude that, when faced with the question, the SJC likely will look to the federal courts’ interpretation of the ÁDEA and hold that an age discrimination claim cannot be grounded solely on a theory of disparate impact.

Cormier v. Pezrow New England, Inc. · filed 2002-07-15(1B)
In sum, the jury’s answer of “yes” to the question whether they found Cormier was terminated due to his age, reflected a conclusion that the proffered reasons for termination were false and that the termination was due to age discrimination. There was ample, albeit contested, evidence at trial on which such a conclusion could be based.Read the full opinion on CourtListener →

A mixed-motive analysis may apply to Section 4 age discrimination claims when strong evidence of animus shifts the burden to the employer to show it would have taken the same action.
Diaz v. JITEN HOTEL MANAGEMENT, INC. · filed 2011-01-20
Under Massachusetts law, by contrast, a mixed-motive analysis may still be appropriate.
