    LYNCH, Circuit Judge.         Since 2021, Maine has required
    certain healthcare facilities to ensure that their non-remote
    workers are vaccinated against COVID-19.             See 
    10-144-264 Me. Code R. § 2
    (A)(7); see also 
    Me. Rev. Stat. Ann. tit. 22, § 802
    .                    We
    refer to this requirement as the "Mandate."             The Mandate permits
    workers to seek exemptions for medical reasons, but not for
    religious ones.        See 
    Me. Rev. Stat. Ann. tit. 22, § 802
    (4-B);
    
    10-144-264 Me. Code R. § 3
    .         Facilities that do not comply with
    the Mandate are subject to penalties, including fines and license
    suspension.     See 
    Me. Rev. Stat. Ann. tit. 22, § 804
    ; 
    10-144-264 Me. Code R. § 7
    (G).
    The plaintiffs in this case are seven Maine healthcare
    workers who allege that their sincerely held religious beliefs
    prevent them from receiving any of the available COVID-19 vaccines.
    After Maine introduced the Mandate, the plaintiffs requested that
    their employers -- healthcare providers Genesis HealthCare of
    Maine,   LLC;    Genesis      HealthCare     LLC;     MaineGeneral       Health;
    MaineHealth;    and    Northern   Light    Eastern    Maine    Medical    Center
    (collectively,    the     "Providers")      --   exempt       them   from    the
    vaccination requirement based on these religious beliefs.                   The
    Providers     denied    the   requests,      explaining       that   religious
    exemptions were not available under state law.                The plaintiffs'
    employment was later terminated after they refused to accept COVID-
    19 vaccination.
    - 3 -
    The    plaintiffs   filed      this   suit   against     three   Maine
    government officials in their official capacities (we refer to
    them collectively as the "State") and the Providers.                  The claims
    against the State assert, among other things, that the Mandate, by
    allowing medical but not religious exemptions, violates the Free
    Exercise and Equal Protection Clauses of the U.S. Constitution.
    Against the Providers, the plaintiffs brought, inter alia, claims
    under Title VII of the Civil Rights Act of 1964, contending that
    the Providers' refusal to accommodate the plaintiffs' religious
    beliefs    by     exempting   them   from    the    vaccination      requirement
    amounted to unlawful employment discrimination on the basis of
    religion.       The district court dismissed the complaint.                   See
    Lowe v. Mills, No. 21-cv-00242, 
    2022 WL 3542187
    , at *1 (D. Me.
    Aug. 18, 2022).
    We agree with the district court that the complaint's
    factual allegations establish that violating the Mandate in order
    to provide the plaintiffs' requested accommodation would have
    caused    undue    hardship   for    the   Providers,     and   so   affirm   the
    dismissal of the Title VII claims.1                But we conclude that the
    plaintiffs' complaint states claims for relief under the Free
    Exercise and Equal Protection Clauses, as it is plausible, based
    on the plaintiffs' allegations and in the absence of further
    1    We also affirm the dismissal of several other claims
    that the plaintiffs do not discuss on appeal.
    - 4 -
    factual development, that the Mandate treats comparable secular
    and       religious      activity    dissimilarly      without    adequate
    justification.        We affirm in part and reverse in part.
    I.
    A.
    Maine law has required that certain licensed healthcare
    facilities ensure that their employees are vaccinated against
    various diseases since 1989.2         See 1989 Me. Laws ch. 487, § 11
    (mandating that employers require proof of either immunization
    against or serologic immunity to measles and rubella). Since 2001,
    the   Maine     Department     of   Health   and    Human   Services   (the
    "Department") has had regulatory authority to designate by rule
    diseases against which healthcare employers must require proof of
    immunization.     See 2001 Me. Laws ch. 185, § 2.      Prior to the COVID-
    19 pandemic, the Department required vaccination for measles,
    mumps, rubella, chickenpox, hepatitis B, and influenza.            10-144-
    264 Me. Code R. §§ 1(F), 2(A) (2021) (amended Aug. 2021).               The
    plaintiffs do not challenge the requirement of vaccination against
    these diseases.
    2   Current law specifies that the vaccination requirements
    apply to "licensed nursing facilit[ies], residential care
    facilit[ies], intermediate care facilit[ies] for persons with
    intellectual disabilities, multi-level health care facilit[ies],
    hospital[s,] [and] home health agenc[ies]." 
    Me. Rev. Stat. Ann. tit. 22, § 802
    (4-A)(A); accord 
    10-144-264 Me. Code R. § 1
    (E).
    - 5 -
    Until     2019,    state          law     allowed       exemptions       from
    healthcare-worker vaccination requirements for most diseases under
    three circumstances: when an employee submitted (1) "a physician's
    written statement that immunization against one or more diseases
    may    be    medically     inadvisable,"         or    a    written     statement      that
    vaccination       was    contrary     to    a    "sincere       [(2)]     religious      or
    [(3)]      philosophical    belief."3           
    Me. Rev. Stat. Ann. tit. 22, § 802
    (4-B)(A)-(B)      (2019)     (amended         2019).     In    2019,    Maine's
    legislature modified these exemptions.                     See 2019 Me. Laws ch. 154,
    §§ 8-9.      First, it amended the medical exemption to apply where
    the    employee    "provides      a   written         statement    from     a   licensed
    physician, nurse practitioner or physician assistant that, in the
    physician's,       nurse     practitioner's            or     physician     assistant's
    professional judgment, immunization against one or more diseases
    may be medically inadvisable."               Id. § 8.         The change took effect
    September 1, 2021.         Id. § 12.       Second, the legislature eliminated
    the religious and philosophical exemptions, with the change taking
    effect April 19, 2020.          See id. § 9.          These modifications were the
    subject of a statewide veto referendum in March 2020; over 72% of
    voters voted to retain the changes.4                  In April 2021, the Department
    3  Maine law also allowed -- and still allows -- an
    exemption for an individual who "declines [a] hepatitis B vaccine,
    as provided for by the relevant [federal] law." 
    Me. Rev. Stat. Ann. tit. 22, § 802
    (4-B)(C). No party argues that this exemption
    is relevant to this case, so we do not discuss it further.
    4      See Tabulations for Elections Held in 2020, Dep't of the
    - 6 -
    amended     its   healthcare-worker         vaccination   rules,    which    had
    previously listed the available exemptions, to cross-reference the
    exemptions allowed by statute.              See 
    10-144-264 Me. Code R. § 3
    (2021) (as amended Apr. 2021; amended Nov. 2021).
    In    June   2021,    the    legislature   amended     the   statute
    governing     enforcement        of   the    healthcare-worker     vaccination
    requirements to augment the potential penalties for violations.
    See 2021 Me. Laws ch. 349, §§ 8-9 (codified at 
    Me. Rev. Stat. Ann. tit. 22, § 804
    (2)-(3)).          The amended statute provides:
    Any person who neglects, violates or
    refuses to obey the [vaccination] rules or who
    willfully obstructs or hinders the execution
    of   the   rules   may  be  ordered   by   the
    [D]epartment . . . to cease and desist. . . .
    In the case of any person who refuses to obey
    a cease and desist order issued to enforce the
    [vaccination] rules . . . , the [D]epartment
    may impose a fine, which may not be less than
    $250 or greater than $1,000 for each
    violation.     Each day that the violation
    remains uncorrected may be counted as a
    separate offense. . . .
    A licensing agency under the [D]epartment
    may immediately suspend a license . . . for a
    violation under this section.
    
    Me. Rev. Stat. Ann. tit. 22, § 804
    (2)-(3).
    In August 2021, the Department conducted an emergency
    rulemaking that added COVID-19 to the list of diseases against
    which   non-remote       healthcare     workers   at   licensed    facilities,

    including the Providers, must be vaccinated.             See 
    10-144-264 Me. Code R. §§ 1
    (F)(7), 2(A)(7) (2021) (as amended Aug. 2021; amended
    Nov. 2021).   The Department made this change permanent in November
    2021.5   See 
    id.
     (as amended Nov. 2021).       The Mandate is the product
    of this rule and the related state statutes.
    B.
    Because this appeal follows a dismissal for failure to
    state a claim, we draw the facts from the plaintiffs' complaint.
    See, e.g., Douglas v. Hirshon, 
    63 F.4th 49
    , 52 (1st Cir. 2023).
    The   plaintiffs   in   this    case   are   seven   individuals
    formerly employed by the Providers in positions covered by the
    Mandate.6   The plaintiffs allege that they object to receiving any
    of the available COVID-19 vaccines on religious grounds "because
    of the connection between the . . . vaccines and the cell lines of
    aborted fetuses . . . in the vaccines' origination, production,
    development, testing, or other inputs," which conflicts with the
    plaintiffs' belief "that all life is sacred, from the moment of
    5    The permanent rule differs in some respects from the
    emergency rule; for instance, it does not cover dental or emergency
    medical services providers, which the emergency rule had reached.
    Compare 
    10-144-264 Me. Code R. § 1
    , with 
    id.
     (2021) (as amended
    Aug. 2021; amended Nov. 2021).       No party argues that these
    differences are relevant to this appeal.
    6    Three of the plaintiffs formerly worked for Northern
    Light Eastern Maine Medical Center, two worked for Genesis
    HealthCare, and one worked for each of MaineGeneral Health and
    MaineHealth.

    conception to natural death, and that abortion is a grave sin
    against God and the murder of an innocent life."
    Each plaintiff   requested a religious            "exemption    and
    accommodation" from his or her employer excusing him or her from
    vaccination.      The plaintiffs "offered, and [were] ready, willing,
    and   able   to   comply   with   .    .    .   [other]    health   and   safety
    requirements to facilitate their religious exemption," such as by
    "wear[ing] facial coverings, submit[ting] to reasonable testing
    and reporting requirements, [and] monitor[ing] symptoms."
    The Providers denied each request, explaining in their
    responses that the Mandate did not permit religious exemptions.
    After the plaintiffs refused to accept vaccination, they were
    terminated from their employment.
    C.
    The original complaint in this action was filed on August
    25, 2021, in the U.S. District Court for the District of Maine
    against   Governor    Janet   Mills,       Department     Commissioner    Jeanne
    Lambrew, and then-Maine Center for Disease Control and Prevention
    ("Maine CDC") Director Nirav Shah7 (the officials we refer to
    collectively as the "State") and the Providers.8               The complaint,
    7   Shah left office while this appeal was pending; Nancy
    Beardsley has been substituted as a defendant-appellee. See Fed.
    R. App. P. 43(c)(2).
    8   The complaint originally named as a defendant the
    Northern Light Health Foundation. Northern Light Eastern Maine
    Medical Center was substituted as a defendant in January 2022,
    - 9 -
    filed using pseudonyms for the plaintiffs, listed as plaintiffs
    six "Jane Does" and three "John Does" who allegedly worked in
    healthcare settings and objected to the Mandate on religious
    grounds.9 Seven of the plaintiffs alleged that they were employees
    or former employees of the Providers, one alleged that he was an
    employer who objected to requiring his employees to comply with
    the Mandate, and one alleged that she was employed by this employer
    plaintiff.
    The complaint included five counts.       Against the State,
    it challenged the Mandate under the First Amendment's Free Exercise
    Clause and the Fourteenth Amendment's Equal Protection Clause.
    Against the Providers, it raised Title VII claims for failure to
    accommodate the plaintiffs' religious beliefs.                And it alleged
    that       all    defendants   had    violated   the    Supremacy    Clause   by
    purportedly        claiming    that   the   Mandate   superseded    Title   VII's
    requirements, and had conspired to violate the plaintiffs' civil
    rights in violation of 
    42 U.S.C. § 1985
    .                The plaintiffs sought
    declaratory and injunctive relief, as well as damages.
    The same day the complaint was filed, the plaintiffs
    moved for a temporary restraining order and preliminary injunction
    prior to the filing of the operative amended complaint.
    9  The complaint also listed as plaintiffs two thousand
    "Jack Does" and "Joan Does" who allegedly had "been told not to"
    seek religious exemptions from the Mandate or had sought such
    exemptions and been denied them.
    - 10 -
    barring the State from enforcing the Mandate against the employer
    plaintiff   and   requiring   the    Providers     to   grant   the   employee
    plaintiffs religious exemptions from COVID-19 vaccination.                The
    district court denied the motion.            See Does 1-6 v. Mills, 
    566 F. Supp. 3d 34
    , 39 (D. Me. 2021).         This court affirmed, concluding
    that the plaintiffs had not shown a likelihood of success on the
    merits, that they would likely suffer irreparable harm absent
    preliminary relief, or that the balance of the equities or the
    public interest favored an injunction.10           See Does 1-6 v. Mills,
    
    16 F.4th 20
    , 29-37 (1st Cir. 2021), cert. denied sub nom. Does 1-
    3 v. Mills, 
    142 S. Ct. 1112 (2022)
    .           The Supreme Court denied the
    plaintiffs' application for injunctive relief, see Does 1-3 v.
    Mills, 
    142 S. Ct. 17
    , 17 (2021) (mem.), and their petition for
    certiorari, see Does 1-3, 142 S. Ct. at 1112.
    10   This court's decision on the plaintiffs' preliminary
    injunction appeal does not control the outcome in this appeal
    because the different procedural postures implicate different
    burdens, standards of review, and factual records. That decision
    evaluated, based on evidence submitted by all parties, whether the
    district court had abused its discretion in denying the preliminary
    injunction motion, and whether the plaintiffs had met their burden
    of showing, among other things, both a likelihood of success on
    the merits and irreparable harm. See Does 1-6 v. Mills, 
    16 F.4th 20
    , 29-30 (1st Cir. 2021), cert. denied sub nom. Does 1-3 v. Mills,
    
    142 S. Ct. 1112 (2022)
    . In contrast, we review a dismissal under
    Federal Rule of Civil Procedure 12(b)(6) de novo based on a record
    limited to the complaint's well-pleaded allegations, which need
    only make out plausible claims with all reasonable inferences drawn
    in the plaintiffs' favor. See, e.g., Frese v. Formella, 
    53 F.4th 1
    , 5-6 (1st Cir. 2022). The defendants properly do not contend
    that the result in Mills is binding in this appeal.
    - 11 -
    After remand to the district court, two Maine newspapers
    intervened    in    the   case   to   challenge       the    plaintiffs'    use   of
    pseudonyms.       The district court granted the newspapers' motion to
    unseal the plaintiffs' identities and ordered the plaintiffs to
    file an amended complaint identifying themselves by name, see Does
    1-6 v. Mills, No. 21-cv-00242, 
    2022 WL 1747848
    , at *7 (D. Me. May
    31, 2022), and this court denied a stay of the order pending
    appeal, see Does 1-3 v. Mills, 
    39 F.4th 20
    , 22 (1st Cir. 2022).
    Following    this    court's     decision,      the    plaintiffs       voluntarily
    dismissed their appeal.
    The     plaintiffs    filed      the   operative       first   amended
    complaint (the "complaint") in July 2022.                   This amended pleading
    removes some of the original plaintiffs (leaving only the seven
    plaintiffs    who    allege    they   were     employed      by   the   Providers),
    identifies the remaining plaintiffs by name, and updates some
    factual allegations to reflect developments since the original
    complaint's filing (such as the plaintiffs' termination from their
    employment with the Providers), but includes the same claims as
    the original complaint.
    The defendants moved to dismiss.                The State argued that
    some of the claims must be dismissed for lack of jurisdiction under
    Federal Rule of Civil Procedure ("Rule") 12(b)(1), asserting that
    the plaintiffs lack standing to sue Governor Mills, who does not
    play a role in enforcing the Mandate, and that the Eleventh
    - 12 -
    Amendment bars the claims for money damages against the State.
    The State did not make similar jurisdictional arguments with
    respect to the non-damages claims for relief against the other
    Maine officials.       The defendants also argued that the plaintiffs'
    allegations with respect to the other counts fail to state claims
    under Rule 12(b)(6).       The plaintiffs opposed the motions, though
    they did not respond to the State's arguments limited to Rule
    12(b)(1).
    The district court granted the defendants' motions and
    dismissed the complaint.         See Lowe, 
    2022 WL 3542187
    , at *1.         It
    first dismissed the claims against Governor Mills and the damages
    claims against the State because the plaintiffs had failed to
    respond to the State's Rule 12(b)(1) arguments.              See 
    id. at *6
    .
    Turning to the Rule 12(b)(6) motions, the court concluded that the
    Mandate is a religiously neutral law of general applicability that
    is     rationally   related     to   Maine's    legitimate   public   health
    interests, and so does not violate the Free Exercise or Equal
    Protection Clauses.      See 
    id. at *10-15
    .        And it reasoned that the
    plaintiffs' factual allegations establish that the Providers could
    not have offered the plaintiffs their requested accommodation
    without    violating    state    law   and     risking   onerous   penalties,
    creating an undue hardship that precludes liability under Title
    VII.    See 
    id. at *6-10
    .       Finally, it concluded that the Supremacy
    Clause does not provide a distinct cause of action and that the
    - 13 -
    complaint's allegations with respect to the conspiracy count were
    too vague and conclusory to support a plausible claim, and so
    dismissed the Supremacy Clause and conspiracy claims.    See 
    id. at *15
    .
    This timely appeal followed.
    II.
    We review a district court's dismissal of a complaint
    under Rule 12(b)(6) de novo.    E.g., Douglas, 63 F.4th at 54-55.
    To avoid dismissal, "[t]he complaint 'must contain sufficient
    factual matter, accepted as true, to state a claim to relief that
    is plausible on its face.'"    Id. at 55 (internal quotation marks

    The plaintiffs' briefing on appeal does not address the
    dismissal of the claims against Governor Mills, the damages claims
    - 14 -
    against the State, or the Supremacy Clause and § 1985 conspiracy
    claims.     The plaintiffs have thus waived any arguments on those
    points, and we affirm those aspects of the district court's
    decision.     See, e.g., Douglas, 63 F.4th at 54 n.6.             That leaves
    the free exercise and equal protection claims against the State
    and the Title VII claims against the Providers at issue.
    A.
    1.
    We begin with the free exercise claim.                 "The First
    Amendment's Free Exercise Clause, as incorporated against the
    states by the Fourteenth Amendment, protects religious liberty
    against government interference."           Mills, 16 F.4th at 29.      A key
    issue with respect to this claim is the appropriate standard of
    scrutiny.     A law that incidentally burdens religion is subject
    only to rational basis review if it is religiously neutral and
    generally applicable.         E.g., id.     A law that is not neutral or
    generally applicable is subject to strict scrutiny.               E.g., id.   A
    law is not generally applicable if it "treat[s] any comparable
    secular     activity   more     favorably    than     religious    exercise."
    Tandon v. Newsom, 
    141 S. Ct. 1294
    , 1296 (2021) (per curiam); see
    also Fulton v. City of Philadelphia, 
    141 S. Ct. 1868
    , 1877 (2021)
    ("A law . . . lacks general applicability if it prohibits religious
    conduct   while   permitting     secular    conduct   that   undermines   the
    government's asserted interests in a similar way.").              Applying the
    - 15 -
    Rule 12(b)(6) standard and drawing all reasonable inferences in
    the plaintiffs' favor, we conclude that it is plausible, in the
    absence of any factual development, that the Mandate falls in this
    category, based on the complaint's allegations that the Mandate
    allows some number of unvaccinated individuals to continue working
    in   healthcare    facilities    based      on     medical    exemptions      while
    refusing   to     allow     individuals       to    continue        working   while
    unvaccinated for religious reasons.
    The    Supreme    Court    has   explained        that    "whether   two
    activities are comparable for purposes of the Free Exercise Clause
    must be judged against the asserted government interest that
    justifies the regulation at issue," and that "[c]omparability is
    concerned with the risks various activities pose."                  Tandon, 141 S.
    Ct. at 1296; see also We the Patriots USA, Inc. v. Hochul, 
    17 F.4th 266
    , 285-88 (2d Cir. 2021) (conducting comparability analysis in
    context of New York vaccine mandate for healthcare workers).
    Tandon, for example, held that a group of plaintiffs was likely to
    succeed in a free exercise challenge to a California law that, in
    response to the COVID-19 pandemic, sought to reduce the virus's
    spread by limiting religious gatherings in homes to no more than
    three households, but "permitt[ed] hair salons, retail stores,
    personal care services, movie theaters, private suites at sporting
    events and concerts, and indoor restaurants to bring together more
    than three households at a time."           141 S. Ct. at 1297; see id. at
    - 16 -
    1298 (Kagan, J., dissenting).           The Court determined that these
    secular activities were comparable to the prohibited religious
    gatherings because the record did not show that they "pose[d] a
    lesser   risk    of    transmission    than   [the   plaintiffs']   proposed
    religious exercise at home."          Id. at 1297 (majority opinion).
    As its principal interest in permitting medical but not
    religious exemptions to the Mandate, the State cites a goal of
    "revers[ing] the trajectory of falling vaccination rates in order
    to   prevent    communicable,    preventable     diseases   from    spreading
    in . . . healthcare facilities . . . so that all persons medically
    unable to be vaccinated [can] be protected."           The State also cites
    a more general interest in "protecting the lives and health of
    Maine people."        (Quoting Lowe, 
    2022 WL 3542187
    , at *14.)        Drawing
    all reasonable inferences in the plaintiffs' favor, it is plausible
    based on the plaintiffs' allegations that the medical exemption
    undermines these interests in a similar way to a hypothetical
    religious exemption.         The availability of a medical exemption,
    like a religious exemption, could reduce vaccination rates among
    healthcare workers and increase the risk of disease spread in
    healthcare facilities, compared to a counterfactual in which the
    Mandate contains no exceptions, all workers must be vaccinated,
    and neither religious objectors nor the medically ineligible can
    continue working in healthcare facilities.           Cf. Tandon, 141 S. Ct.
    at 1297 (comparing risk of disease transmission).
    - 17 -
    The State argues that comparing the risks created by the
    two exemptions in this way is inappropriate because "Maine's
    asserted interest in providing only a medical exemption . . . is
    not based on comparative assessments of risk," but instead on
    keeping vaccination rates high to protect Mainers, and especially
    Mainers medically unable to be vaccinated.           But the State has not
    asserted an independent interest in maximizing vaccination rates
    apart from the public health benefits of doing so, and the Supreme
    Court has instructed us to assess comparability in the public
    health context based on "the risks various activities pose."             Id.
    at 1296.    The State's argument that it did not independently
    conduct this type of analysis is, if anything, a reason to be
    skeptical that dismissal is appropriate absent further factual
    development.
    The State also references in passing an interest in
    "safeguarding Maine's healthcare capacity."           (Quoting Lowe, 
    2022 WL 3542187
    , at *14.)     While excusing some workers from vaccination
    for medical reasons may protect Maine's "healthcare capacity" by
    making more workers available, authorizing a religious exemption
    plausibly could have a similar effect.            We thus cannot conclude,
    at least without more facts, that this interest renders the two
    exemptions incomparable.
    The   State   asserts    that    the    medical   exemption    is
    "fundamentally different . . . [from] a religious exemption because
    - 18 -
    a medical exemption aligns with the State's interest in protecting
    public      health     and,      more    specifically,        medically    vulnerable
    individuals       from       illness    and   infectious     diseases,    while   non-
    medical exemptions . . . do not."                (Quoting Lowe, 
    2022 WL 3542187
    ,
    at *12.) But, drawing all reasonable inferences in the plaintiffs'
    favor, it is plausible that a version of the Mandate that did not
    include a medical exemption could do an even better job of serving
    the State's asserted public health goals, and that the inclusion
    of the medical exemption undermines the State's interests in the
    same     way    that     a     religious      exemption      would   by   introducing
    unvaccinated individuals into healthcare facilities.
    Of course, it is entirely possible that additional facts
    might show that the two types of exemption are not comparable.
    For example (and not by way of limitation), it may be that medical
    exemptions are likely to be rarer, more time limited, or more
    geographically diffuse than religious exemptions, such that the
    two exemptions would not have comparable public health effects.
    Cf.    We   the   Patriots,        17    F.4th    at   286    (discussing    evidence
    suggesting that medical and religious exemptions to a New York
    vaccine mandate were "not comparable in terms of the 'risk' that
    they pose[d]" (quoting Tandon, 141 S. Ct. at 1296)).                        We reject
    the plaintiffs' apparent view that the only relevant comparison is
    between the risks posed by any one individual who is unvaccinated
    for religious reasons and one who is unvaccinated for medical
    - 19 -
    reasons.   Instead, we agree with the Second Circuit that Supreme
    Court   precedent   "suggests   the    appropriateness   of   considering
    aggregate data about transmission risks."        Id. at 287; see id. at
    286-87 ("We doubt that, as an epidemiological matter, the number
    of people seeking exemptions is somehow excluded from the factors
    that the State must take into account in assessing the relative
    risks to the health of healthcare workers and the efficacy of its
    vaccination strategy . . . .").       But, absent factual development,
    dismissal is unwarranted.
    The State does advance a comparability argument based on
    facts outside the complaint that it argues we may nonetheless
    properly consider.    The State cites a Federal Centers for Medicare
    and Medicaid Services ("CMS") interim final rule governing staff
    vaccination   requirements      in    certain   healthcare    facilities,
    including hospitals and long-term care facilities, that receive
    Medicare and Medicaid funds, which the State represents "covers
    many of the same healthcare entities as Maine's [Mandate]."           See
    Medicare and Medicaid Programs; Omnibus COVID-19 Health Care Staff
    Vaccination, 
    86 Fed. Reg. 61,555
     (Nov. 5, 2021) (codified at 42
    C.F.R. pts. 416, 418, 441, 460, 482-86, 491, 494).             The State
    observes that CMS's explanation of the regulation states that the
    rule preempts state laws "providing for exemptions to the extent
    such law[s] provide[] broader grounds for exemptions than provided
    for by Federal law," 
    id. at 61,613
    , and argues that the medical
    - 20 -
    exemption permitted under the CMS rule, which requires a worker
    seeking    an   exemption     to   provide    signed    documentation   from   a
    "licensed practitioner" that the worker has "recognized clinical
    contraindications to COVID-19 vaccines," e.g., 
    id. at 61,619-20
    ,
    is more restrictive than the medical exemption under Maine law,
    see 
    Me. Rev. Stat. Ann. tit. 22, § 802
    (4-B)(A), such that, in
    practice, only the narrower medical exemption under the CMS rule
    will be available in at least some of the facilities covered by
    the Mandate.
    The State then argues that this narrower CMS medical
    exemption would permit only a small number of healthcare workers
    to obtain medical exemptions from the Mandate.                  Citing a U.S.
    Centers for Disease Control and Prevention ("CDC") fact sheet, the
    State     represents   that    "CDC[-]recognized        contraindications      to
    vaccination      are   limited       to      [(1)]     known   allergies    [to
    vaccine     components],      [and    (2)]     severe     allergic   reactions
    (anaphylaxis) . . . and [(3)] cardiac conditions (TTS) occurring
    after the administration of a prior dose of a COVID-19 vaccine."11
    Citing a CDC webpage, the State argues that at least two of these
    11   The original source cited by the State appears no longer
    to be available online. For an archived version, see U.S. CDC,
    Summary Document for Interim Clinical Considerations for Use of
    COVID-19 Vaccines Currently Authorized or Approved in the United
    States     (Dec.    6,     2022),    https://web.archive.org/web/

    summary-interim-clinical-considerations.pdf.
    - 21 -
    three contraindications are vanishingly rare -- with approximately
    five instances of anaphylaxis and four cases of TTS occurring per
    million vaccine doses administered -- such that "the approximately
    11 or 12 persons that would suffer an adverse reaction to a COVID-
    19 vaccination based on Maine's entire population (not just persons
    subject to the [Mandate]) is about the same [as the] number of
    [plaintiffs] in this appeal."12             On that basis, the State argues
    that    "[t]he      risks   between      medical   and    religious   exemptions
    are . . . not comparable."
    Comparisons of this sort may well be relevant to the
    comparability inquiry.        See We the Patriots, 17 F.4th at 286.            But
    these limited data are insufficient to resolve the comparability
    inquiry at the motion-to-dismiss stage -- even assuming we may
    properly consider them. Cf. Freeman, 
    714 F.3d at 35-37
     (discussing
    limits      on    consideration     of     materials     outside   complaint   in
    evaluating motion to dismiss).              Even accepting, for the sake of
    argument, the State's premise that the narrower medical exemption
    under the CMS rule is relevant to the comparability analysis in
    this case, its interpretation of the CMS rule and the CDC's
    clinical         recommendations,     and    its    calculations      about    the
    prevalence of anaphylaxis and TTS, there are several significant

    adverse-events.html.
    - 22 -
    gaps in the State's argument.        First, the State does not explain
    how many facilities and workers covered by the Mandate actually
    fall within the CMS rule's coverage, simply stating that "many"
    do.13        Second, it does not address how many individuals might
    qualify for medical exemptions under the CMS rule based on known
    allergies       to   COVID-19   vaccines;   it   instead   discusses   the
    prevalence of only two of the three contraindications it describes.
    Third, the State's argument does not show how many individuals
    would likely seek religious exemptions from the Mandate, were they
    available, instead assuming that the number would be significantly
    greater than the number of plaintiffs in this case.           Given those
    gaps, and the requirement at this stage to draw all reasonable
    inferences in the plaintiffs' favor, it remains plausible that the
    Mandate's medical exemption creates comparable risks to those that
    would be created by a religious exemption, warranting strict
    scrutiny.14
    13The plaintiffs' counsel stated at oral argument that the
    plaintiffs in this case worked at facilities covered by the CMS
    rule. But the State has not developed any argument that we should
    look only at facilities covered both by the CMS rule and the
    Mandate for purposes of assessing the Mandate's constitutionality.
    We express no view on the merits of such an argument, were the
    State to advance it, but, absent such an argument, we decline to
    so constrain the inquiry.
    14Our conclusion that it is plausible that the Mandate is
    subject to strict scrutiny on this basis makes it unnecessary at
    this stage to address the other arguments for strict scrutiny
    advanced by the plaintiffs, such as the assertion that the Mandate
    is not generally applicable because it creates "a mechanism for
    individualized exemptions." Fulton, 141 S. Ct. at 1877 (quoting
    - 23 -
    Because it is plausible, based on the complaint and
    without the benefit of factual development, that the Mandate is
    subject to strict scrutiny, dismissal would be appropriate only if
    the materials we may consider on a motion to dismiss establish
    that the   Mandate    survives that standard of review             even when
    applying the Rule 12(b)(6) plausibility standard.             Cf. Zenon v.
    Guzman, 
    924 F.3d 611
    , 616 (1st Cir. 2019) (discussing circumstances
    in which affirmative defense, for which defendant bears burden of
    proof, may be adjudicated on motion to dismiss).            Strict scrutiny
    requires the State to show that the Mandate is narrowly tailored
    to advance a compelling government interest.           See, e.g., Fulton,
    141 S. Ct. at 1881.      "Put another way, so long as the government
    can   achieve   its   interests   in   a   manner   that   does   not   burden
    religion, it must do so."     Id.
    The State does briefly contend that the Mandate survives
    strict scrutiny, but its argument does not justify dismissal on
    the pleadings.    It argues that a statement issued by the Maine CDC
    in November 2021, when the agency made the regulation requiring
    COVID-19 vaccination for healthcare workers permanent, establishes
    that the Mandate is the least restrictive means to achieve the
    State's public health goals.      The statement discusses the agency's
    reasoning concerning why alternative measures, such as mandatory
    Emp. Div. v. Smith, 
    494 U.S. 872
    , 884 (1990)).
    - 24 -
    masking, were insufficient to prevent the spread of COVID-19.                    But
    the cited discussion is insufficient, standing alone, to satisfy
    the State's burden under strict scrutiny.                  For example, it does
    not address the likely effects of including a religious exemption
    in the Mandate or give reasons why doing so would prevent the state
    from achieving its public health goals.15                   Cf. id. at 1881-82
    (holding that a government defendant had not shown that a religious
    exemption to a challenged policy would undermine the interests the
    policy aimed to advance so as to satisfy strict scrutiny).                      As a
    result, even assuming we may properly consider the statement at
    the motion-to-dismiss stage, cf. Freeman, 
    714 F.3d at 35-37
    , it
    does not establish that the Mandate satisfies strict scrutiny and,
    thus, that dismissal is appropriate.
    We emphasize the narrowness of our holding.              We do not
    determine what standard of scrutiny should ultimately apply to the
    free exercise claim. Nor do we decide whether the Mandate survives
    the applicable level of scrutiny.             Those questions are not before
    us.        We   hold    only   that,   applying   the     plausibility    standard
    applicable to Rule 12(b)(6) motions and drawing all reasonable
    inferences       from    the    complaint's     factual    allegations     in    the
    15  A portion of the agency's statement not cited by the
    State does reference the possibility of religious exemptions to
    the Mandate, but only in observing that the state legislature had
    eliminated the option for such exemptions by statute in 2019. It
    does not independently analyze the likely effects of such
    exemptions.
    - 25 -
    plaintiffs' favor, the complaint states a claim under the Free
    Exercise Clause.
    2.
    We next consider the plaintiffs' equal protection claim,
    which alleges that the Mandate burdens their free exercise rights
    and discriminates on the basis of religion.                   The district court
    reasoned that, because it had concluded that the free exercise
    claim warranted only rational basis review, an equal protection
    claim resting on the assertion that the                      Mandate burdens       the
    plaintiffs' free exercise rights must also receive rational basis
    review.    Lowe, 
    2022 WL 3542187
    , at *14-15 (citing Wirzburger v.
    Galvin,    
    412 F.3d 271
    ,   282-83     (1st      Cir.   2005)).     The     court
    determined that the Mandate survives rational basis review under
    the Equal Protection Clause for the same reasons as in the free
    exercise context.        See 
    id. at *15
    .         On appeal, the State endorses
    this reasoning.          It does not develop any argument that, if we
    reverse    the    dismissal      of   the      free    exercise   claim,    we     can
    nonetheless affirm the dismissal of the equal protection claim.
    As a result, because we reverse the dismissal of the free exercise
    claim, we also reverse the dismissal of the equal protection claim.
    B.
    We turn to the plaintiffs' Title VII claims against their
    former employers, the Providers.                 As relevant here, Title VII
    declares     it     an     "unlawful        employment        practice     for     an
    - 26 -
    employer . . . to discharge any individual, or otherwise to
    discriminate         against     any      individual        with     respect      to     his
    compensation, terms, conditions, or privileges of employment,
    because    of       such    individual's     .   .     .    religion."       42    U.S.C.
    § 2000e-2(a).         The statute defines "religion" to "include[] all
    aspects of religious observance and practice, as well as belief,
    unless an employer demonstrates that he is unable to reasonably
    accommodate to an employee's . . . religious observance or practice
    without undue hardship on the conduct of the employer's business."
    Id. § 2000e(j).
    This court "appl[ies] a two-part framework in analyzing
    religious           discrimination          claims          under       Title          VII."
    Sánchez-Rodríguez v. AT & T Mobility P.R., Inc., 
    673 F.3d 1
    , 12
    (1st Cir. 2012). "First, [a] plaintiff must make [her] prima facie
    case   that     a    bona    fide   religious        practice       conflicts     with   an
    employment      requirement         and   was    the       reason    for   the    adverse
    employment action."            
    Id.
     (quoting Cloutier v. Costco Wholesale
    Corp., 
    390 F.3d 126
    , 133 (1st Cir. 2004)).                          "[T]he burden then
    shifts to the employer to show that it offered a reasonable
    accommodation or, if it did not offer an accommodation, that doing
    so would have resulted in undue hardship."                     Cloutier, 
    390 F.3d at 133
    .      The Providers do not dispute that the plaintiffs have
    adequately alleged a prima facie case sufficient to survive a Rule
    12(b)(6) motion, and do not claim that they offered any reasonable
    - 27 -
    accommodation of the plaintiffs' religious practices.      As to the
    Providers, this appeal thus turns on their undue hardship defense.
    Although undue hardship is an affirmative defense, see
    
    id.,
     dismissal on a Rule 12(b)(6) motion is nonetheless appropriate
    if "the facts establishing the defense [are] clear on the face of
    the plaintiff[s'] pleadings" and "there is 'no doubt' that the
    plaintiff[s'] claim[s] [are] barred," Zenon,

    244 F.3d 193
    , 197 (1st Cir. 2001)).   The complaint and the plaintiffs'
    briefing make clear that the plaintiffs would accept only one
    accommodation: a religious exemption allowing them to continue in
    their roles without receiving a vaccine while observing other
    precautions, such as masking and testing.16      We thus need only
    determine whether that accommodation would have constituted an
    undue hardship.17   See Cloutier, 
    390 F.3d at 134-35
    .   We agree with
    16    In their reply brief, the plaintiffs attempt to draw a
    distinction between their requested exemption from the Mandate and
    what they separately describe as their proposed accommodation of
    continuing in their previous roles while complying with safeguards
    such as masking and testing. Because this issue was not raised in
    their opening brief, we deem it waived.     See, e.g., FinSight I
    LP v. Seaver, 
    50 F.4th 226
    , 235 (1st Cir. 2022).
    17   At points in their briefing, the plaintiffs take issue
    with the alleged failure by the Providers to "provide at least a
    process for seeking an accommodation." As this court has explained
    in the context of the Americans with Disabilities Act, "liability
    for failure to engage in an interactive process depends on a

    1.
    Maine law makes clear that, by providing the plaintiffs
    their requested accommodation as described in the complaint, the
    Providers would have risked onerous penalties, including license
    suspension.    The Mandate requires the Providers to "require for
    all employees who do not exclusively work remotely [and who are
    not medically exempted] a [c]ertificate of [i]mmunization . . .
    against . . . COVID-19."      
    10-144-264 Me. Code R. § 2
    (A); see 
    Me. Rev. Stat. Ann. tit. 22, § 802

    10-144-264 Me. Code R. § 3
     (permitting medical exemptions by cross-
    referencing section 802).     Granting the plaintiffs their requested
    religious   exemption    would    thus    have   placed   the   Providers   in
    violation of the Mandate.        The penalties for such a violation are
    burdensome.    By statute, the Department's licensing authorities
    "may immediately suspend a [healthcare facility's] license . . .
    for a violation [of the Mandate]," and regulators may also impose
    substantial fines.

    orders to violators, with noncompliance punishable by fines of up
    to $1,000 per violation per day).
    The complaint itself acknowledges the threat to the
    Providers' licenses.     Quoting a press release from the Governor's
    office announcing the Mandate, it states: "[T]he [healthcare]
    organizations to which th[e] [Mandate] applies must ensure that
    each employee is vaccinated, with this requirement being enforced
    as a condition of the facilities' licensure."18        The complaint then
    declares (in bolded text): "Thus, the Governor has threatened to
    revoke the licenses of all health care employers who fail to
    mandate that all employees receive the COVID-19 vaccine."                  The
    only    reasonable   inference   from   this   allegation     and   from   the
    relevant Maine law, both of which we may properly consider in
    reviewing the dismissal of the Title VII claims, see Eves v.
    LePage, 
    927 F.3d 575
    , 578 n.2 (1st Cir. 2019) (en banc), is that
    granting    the   requested   accommodation    would   have    exposed     the
    Providers to a substantial risk of license suspension, as well as
    monetary penalties.
    The plaintiffs' counsel essentially agreed with this
    conclusion at oral argument.      Counsel observed that the State had

    "made clear that . . . exemptions could be granted only for medical
    reasons," that granting the plaintiffs' desired accommodation
    would   require   violating   the   Mandate,   and    that   "noncompliant
    employers would face fines and loss of licensure."           He reiterated:
    Maine . . . [went] to the extreme to say [that]
    no one can grant a religious exemption, and
    that if an employer grants a religious-based
    exemption, they could lose their license and
    they will be fined. That is an extraordinary
    step by the State of Maine against its
    employers . . . . It puts the employers to a
    great extent in this damned-if-you-do, damned-
    if-you-don't . . . situation.
    And   he   acknowledged   that   "obviously,   [the    plaintiffs']   real
    interest is with the State."
    The risk of license suspension for violating the Mandate
    would have constituted an "undue hardship on the conduct of the
    [Providers'] business" under any plausible interpretation of that
    phrase.    42 U.S.C. § 2000e(j).     Title VII does not define "undue
    hardship," see id. § 2000e, but current law holds that "[a]n
    accommodation constitutes an 'undue hardship' if it would impose
    more than a de minimis cost on the employer," Cloutier, 
    390 F.3d at
    134 (citing Trans World Airlines, Inc. v. Hardison, 
    432 U.S. 63
    , 84 (1977)).     Cloutier, for example, held that it would have
    caused undue hardship to require a retailer to permit a cashier to
    wear facial piercings while working "because [doing so] would
    adversely affect the employer's public image," as the retailer
    "ha[d] made a determination that facial piercings, aside from
    - 31 -
    earrings, detract from the 'neat, clean and professional image'
    that it aim[ed] to cultivate," and "[s]uch a business determination
    [was] within [the retailer's] discretion."          
    Id. at 136
    ; see 
    id. at 135-36
    .   The hardship in this case is far more significant: rather
    than having some intangible effect on the Providers' public images
    that could -- in their own discretionary judgment -- eventually
    harm their revenues, license suspension would concretely disrupt
    the    Providers'   "conduct   of    [their]      business."      42   U.S.C.
    § 2000e(j).
    We are aware that the Supreme Court has heard argument
    in a case in which the petitioner asks it to reconsider the more-
    than-de-minimis-cost    interpretation       of    "undue   hardship,"    see
    Groff v. DeJoy, No. 22-174 (U.S. argued Apr. 18, 2023), but our
    holding is not dependent on that formulation of the legal standard.
    Rather, we hold that the plaintiffs' requested accommodation would
    have    constituted    an   undue     hardship      under   any    plausible
    interpretation of the statutory text.          For example, the Americans
    with Disabilities Act ("ADA") also includes an "undue hardship"
    defense: the Act forbids "discriminat[ion] [in employment] against
    a qualified individual on the basis of disability," 42 U.S.C
    § 12112(a), including by "not making reasonable accommodations to
    the known physical or mental limitations of an otherwise qualified
    individual with a disability . . . unless [the employer] can
    demonstrate that the accommodation would impose an undue hardship
    - 32 -
    on the operation of [its] business," id. § 12112(b)(5)(A).               The
    statute defines "undue hardship" to "mean[] an action requiring
    significant difficulty or expense, when considered in light of [a
    statutorily defined list of] factors."         Id. § 12111(10)(A); see
    also Small v. Memphis Light, Gas & Water, 
    952 F.3d 821
    , 826-27
    (6th   Cir.   2020)   (Thapar,    J.,   concurring)     (arguing   for   an
    interpretation of "undue hardship" under Title VII that requires
    "significant costs on the [employer]"); Brief for Petitioner at
    17-28, Groff, No. 22-174 (U.S. Feb. 21, 2023) (similar).           The risk
    of license suspension facing the Providers would readily meet this
    standard, too; indeed, it is difficult to imagine a penalty that
    would cause a healthcare provider more significant difficulty
    "[i]n the conduct of [its] business," 42 U.S.C. § 2000e(j), than
    license suspension.    Cf. EEOC v. Amego, Inc., 
    110 F.3d 135
    , 148 &
    n.15 (1st Cir. 1997) (concluding that accommodation would have
    constituted undue hardship under ADA where it would have required
    nonprofit to hire additional staff it could not realistically
    afford).
    Other   circuits'     caselaw   addressing    the   interaction
    between Title VII's undue hardship defense and state law supports
    our conclusion.    For example, the Third Circuit, in United States
    v. Board of Education, 
    911 F.2d 882
     (3d Cir. 1990), concluded that
    an accommodation would have constituted an undue hardship for an
    employer school board where it would have required the board's
    - 33 -
    administrators    to    violate   a   state   criminal   statute,   thereby
    "expos[ing] [the] administrators to a substantial risk of criminal
    prosecution, fines, and expulsion from the profession."19           
    Id. at 891
    ; see 
    id. at 890-91
    .       While violating the Mandate would not
    carry a risk of criminal charges, it would create a substantial
    risk of enforcement, fines, and license suspension.           Indeed, the
    threat to the Providers' business is, if anything, more direct in
    this case than in Board of Education, where the court discussed a
    risk of charges against the defendant's employees, see 
    id. at 891
    ;
    here, the objects of enforcement actions would be the Providers
    themselves, see 
    Me. Rev. Stat. Ann. tit. 22, § 804
    (2)-(3).
    The Ninth Circuit has similarly held that accommodations
    that    would   force   private   employers    to   "risk   liability   for
    violating" state law constitute undue hardships under Title VII.20
    19 The Third Circuit declined to "address the situation in
    which . . . the chances of enforcement are negligible and
    accommodation involves no realistic hardship," or "the situation
    in which the defendant is a government entity with the
    authority . . . to control whether or not enforcement actions will
    be brought." 
    911 F.2d at 891
    . No such situation obtains here: as
    discussed above, neither state law nor the complaint provide any
    reason to doubt that enforcement was likely.
    20 The Ninth Circuit recently declined to extend this rule
    to a state agency acting as an employer, reasoning that the agency
    was "part of the very state government that [was] responsible for
    creating and enforcing" the state law at issue, such that there
    was a lesser likelihood that the state law would be enforced
    against the agency and a risk that states could pass laws designed
    to excuse their agencies from compliance with Title VII.

    , 329-30 (5th
    Cir. 2013) (citing Sutton with approval in a case involving a
    proposed accommodation that would require an employer to violate
    federal law).
    Several circuits have also held that accommodations that
    would require employers to violate other federal laws are not
    required by Title VII -- sometimes on the theory that such a
    violation precludes the plaintiff from making out a prima facie
    case, and sometimes on the theory that such an accommodation would
    constitute an undue hardship.           See Truskey v. Vilsack, No. 21-
    5821, 
    2022 WL 3572980
    , at *3 (6th Cir. Aug. 19, 2022) (unpublished
    decision) (collecting cases from Fourth, Sixth, Eighth, Ninth,
    Tenth, and Eleventh Circuits).
    We need not and do not decide whether every accommodation
    that would require an employer to violate state or federal law
    would necessarily constitute an undue hardship under Title VII.
    But   these    out-of-circuit        decisions   confirm      that   potential
    private employers, so this reasoning does not apply here.
    - 35 -
    penalties     for    violating       other    laws   can    render       a    proposed
    accommodation an undue hardship.              And, for the reasons described
    above, we hold that this case falls in that category.
    2.
    The plaintiffs' counterarguments fail.                     Importantly,
    they do not develop any meaningful argument that the risk of
    license suspension in this case is insufficiently burdensome as to
    have constituted an undue hardship for the Providers.                        Indeed, as
    discussed     above,    the    plaintiffs'       counsel        at   oral     argument
    acknowledged the difficulty faced by the Providers, characterizing
    it as a "damned-if-you-do, damned-if-you-don't . . . situation."
    The plaintiffs instead argue that factual issues make dismissal
    under Rule 12(b)(6) inappropriate and that Title VII preempts the
    Mandate   and     requires     the    Providers      to    grant     the      requested
    accommodation.       We find these contentions unpersuasive.
    The     plaintiffs      assert    generally     that     whether      their
    requested accommodation would constitute an undue hardship "is a
    question of fact not suitable for determination on a motion to
    dismiss."       As discussed above, however, we conclude that the
    complaint's allegations and the relevant Maine law permit no
    reasonable    inference       but    that    granting     the    plaintiffs      their
    requested accommodation would have exposed the Providers to a
    substantial     risk   of     license    suspension       and    other       penalties,
    creating an undue hardship. See Zenon, 
    924 F.3d at 616
     (discussing
    - 36 -
    adjudication of affirmative defenses at Rule 12(b)(6) stage); see
    also Iqbal, 
    556 U.S. at 678
     (describing Rule 12(b)(6) plausibility
    standard).
    The plaintiffs offer two more specific purported factual
    issues that, they argue, preclude dismissal, but these arguments
    fare no better.     First, they contend that they "plead[ed] and
    offered available alternatives to compulsory vaccination," such as
    masking and testing.      This argument misunderstands the undue
    hardship that the Providers cite, which is not the safety risk
    from allowing the plaintiffs to work while unvaccinated, but
    instead the penalties that the Providers would have faced for
    violating the Mandate.    Those penalties would have applied -- and
    constituted an undue hardship -- regardless of the factual merits
    of the plaintiffs' view that their proposed alternatives would be
    adequate in terms of safety.
    Second, the plaintiffs argue in their briefing, based on
    a Department guidance document, that their requested accommodation
    would not actually have violated the Mandate.            The guidance
    document at issue states that the Mandate "does not prohibit
    employers from providing accommodations for employees' sincerely
    held   religious   beliefs,   observances,   or   practices   that   may
    otherwise be required by Title VII," but that "implementation, if
    such accommodations are provided by a [healthcare employer], must
    - 37 -
    comply with the [Mandate]."21        The plaintiffs assert that the first
    piece of quoted language shows that the Providers could lawfully
    have granted their requested accommodation.                But this reading
    ignores the second piece of quoted language; read as a whole, the
    guidance    document   makes       plain   that   employers     could    provide
    religious accommodations other than exemptions (for instance, by
    authorizing remote work, which would place the worker outside the
    Mandate's scope) but could not offer religious exemptions to
    workers covered by the Mandate (since doing so would not comply
    with the Mandate).         The plaintiffs have never alleged or argued
    that they would have accepted any accommodations that would have
    placed    them outside the Mandate's scope.             And certainly the
    Providers   could    not    have   confidently    relied   on    the    guidance
    document to conclude that offering religious exemptions would not
    expose them to penalties for violating the Mandate, such as would
    render    the   plaintiffs'    requested      accommodation     not     an   undue
    hardship.       Indeed, the plaintiffs' counsel appeared to retreat
    from this argument at oral argument, recognizing that "the Maine
    CDC made clear that . . . exemptions could be granted only for
    medical reasons," and that "if [the Providers] . . . even consider
    21   Health Care Worker Vaccination FAQs, State of Me. COVID-
    19 Response (Nov. 10, 2021), https://www.maine.gov/covid19/
    vaccines/public-faq/health-care-worker-vaccination.
    - 38 -
    [religious exemptions], then they're violating the . . . Mandate."
    The guidance document does not save the Title VII claim.
    In their final counterargument, the plaintiffs assert
    that Title VII preempts the Mandate, such that the Providers were
    required to offer the requested             accommodation notwithstanding
    state law. The Supreme Court has explained that Title VII preempts
    state laws "only if they actually conflict with federal law." Cal.
    Fed. Sav. & Loan Ass'n v. Guerra, 
    479 U.S. 272
    , 281 (1987); see
    
    id. at 281-83
     (discussing "[t]he narrow scope of pre-emption
    available under [Title VII]").            The plaintiffs' argument fails
    because there is no "actual[] conflict" in this case.             As relevant
    here, Title VII could preempt the Mandate only if it required the
    Providers to grant the plaintiffs' requested accommodation.                  But
    granting that accommodation would have exposed the Providers to
    penalties for violating the Mandate, and thus constituted an undue
    hardship not required by Title VII.
    This   conclusion      follows    from   Title     VII's   text   and
    structure, which make clear that the undue hardship analysis
    precedes any conclusion about preemption of state law.                The undue
    hardship   defense   is   built    into     the   statutory    definition     of
    "religion," see 42 U.S.C. § 2000e(j), such that an employment
    action cannot constitute discrimination on the basis of religion,
    and an employer cannot be liable under Title VII for religious
    discrimination, if the undue hardship defense applies, see, e.g.,
    - 39 -
    Bd. of Educ., 
    911 F.2d at 886
    .              In other words,       while the
    plaintiffs' counsel at oral argument stated that the need to comply
    with the Mandate, on the one hand, and with Title VII, on the
    other, placed the Providers in a "damned-if-you-do, damned-if-you-
    don't . . . situation," the undue hardship defense clearly applies
    on the pleadings.     Because the requested accommodation would have
    imposed undue hardship, Title VII does not require it.
    The   plaintiffs   rely   on   42   U.S.C.   §   2000e-7,       which
    provides:
    Nothing in [Title VII] shall be deemed to
    exempt or relieve any person from any
    liability, duty, penalty, or punishment
    provided by any present or future law of any
    State . . . , other than any such law which
    purports to require or permit the doing of any
    act which would be an unlawful employment
    practice under [Title VII].
    They argue that this provision exempts the Providers from liability
    for violating the Mandate, which, they assert, purports to require
    the Providers to violate Title VII by denying them their preferred
    accommodation.
    The plaintiffs' position takes an extremely broad view
    of Title VII's requirements for employers.          Cf. We the Patriots,
    17 F.4th at 291-92 (explaining that "Title VII does not require
    covered   entities   to   provide     [whatever]   accommodation        .    .   .
    [p]laintiffs prefer").     But we need not address the merits of this
    interpretation because, in any event, the Providers do not have
    - 40 -
    enforcement authority with respect to the Mandate, and they have
    no power to determine for the State that the Mandate is invalid
    under Title VII.   Violating the Mandate would thus have exposed
    them to a risk of immediate license suspension -- an undue hardship
    that Title VII did not require them to suffer.22
    The   applicability    of   the   undue    hardship    defense
    distinguishes this case from those the plaintiffs cite applying
    § 2000e-7 in the context of alleged racial discrimination -- where
    Title VII offers no undue hardship defense.      See, e.g., Guardians
    Ass'n of the N.Y.C. Police Dep't, Inc. v. Civ. Serv. Comm'n, 
    630 F.2d 79
    , 104-05 (2d Cir. 1980) (explaining that an employer could
    not justify an employment policy with a "disparate racial impact"
    based on the "requirements of state law").      The plaintiffs cite no
    case holding that Title VII preempted a state law in analogous
    circumstances   involving   religion,    and,   as   discussed    above,
    multiple circuits have held that potential penalties under state
    22   The plaintiffs have never argued that there were any
    steps the Providers could or should have taken to test the
    Mandate's legal validity under Title VII or to determine whether
    granting the plaintiffs their requested accommodation would result
    in enforcement actions by the State, short of defying the Mandate
    and risking penalties.    We thus need not decide whether taking
    such steps would have constituted an undue hardship. Cf., e.g.,
    Seaworth v. Pearson, 
    203 F.3d 1056

    that it would have been an undue hardship to require an employer
    to seek a waiver from an IRS requirement that employers provide
    their employees' Social Security numbers to the agency).

    We conclude that the Title VII claims were properly
    dismissed.
    III.
    For the foregoing reasons, we affirm the dismissal of
    the plaintiffs' claims under the Supremacy Clause, § 1985, and
    Title VII.    We also affirm the dismissal of the plaintiffs' claims
    against Governor Mills and their damages claims against the State.
    We reverse the dismissal of the remaining claims, and remand for
    proceedings consistent with this opinion.    All parties shall bear
    their own costs.
