MAN, PLLC, Charleston, West Virginia, for Appellant/Cross-
Appellee. Constantinos George Panagopoulos, BALLARD

Appellants.


                          OPINION

THACKER, Circuit Judge:

   Benjamin S. Reynolds ("Appellant") appeals the district
court’s award of summary judgment in favor of the American
National Red Cross and the American Red Cross Greenbrier
Valley Chapter (collectively, "Appellees"). The district court
held that Reynolds failed to submit sufficient evidence to
meet his burden with regard to various Americans with Dis-
abilities Act ("ADA") claims. Despite their victory below,
Appellees nonetheless cross-appeal on the ancillary issue of
whether the number of employees of the National Red Cross
and the Greenbrier Valley Chapter can be aggregated for pur-
poses of determining "employer" status under the ADA. For
the reasons that follow, we affirm the district court’s award of
summary judgment to Appellees, vacate the district court’s
ruling that the Greenbrier Valley Chapter is an "employer"
under the ADA, and dismiss the cross-appeal.

                               I.

                              A.

   Reynolds worked for the Greenbrier Valley Chapter of the
American Red Cross in Lewisburg, West Virginia (the "Chap-
ter"). He began as a volunteer in 1994 and then worked as a
per diem instructor beginning in 2004, being paid for each
4           REYNOLDS v. AMERICAN NATIONAL RED CROSS
health/safety, first aid, and CPR class he taught. He eventually
became a part-time employee in 2005. For the entire time he
was with the Chapter, Reynolds worked directly for Walter
M. Lockhart, Executive Director.1 Reynolds and Lockhart met
some years previously when they both volunteered with the
Civil Air Patrol. They interacted socially "every few days,"
J.A. 509,2 and Lockhart loaned Reynolds around $6,000 over
the course of their friendship.

   In 2006, Lockhart offered Reynolds a full-time job with the
chapter as a "Manager of Service Delivery," a job description
that Lockhart drafted himself, and Reynolds accepted. Reyn-
olds began work in that position on or about August 1, 2006.
The job description provided, "[j]ob is physically comfort-
able; individual has discretion about walking, standing, etc."
J.A. 114.31. It also required Reynolds to "[t]each[ ] training
courses as necessary" and "recruit[ ] and retain[ ] volunteer
instructors for community classes and mission related
courses." 

The parties agree "90% of
[Reynolds’s] job was to teach health and safety classes. How-
ever, [he] was also tasked with recruiting or soliciting training
classes from the community." 

salary was listed
at $23,600.00 annually with no benefits.3
    1
     Reynolds sued Lockhart as well, but Lockhart was dismissed by a pre-
vious order of the district court. See Reynolds v. Am. Nat’l Red Cross, No.
5:10-cv-00443, 

(S.D. W. Va. Sept. 26, 2011). Reyn-
olds is not appealing that order.
   2
     Citations to the "J.A." refer to the Joint Appendix filed by the parties
in this appeal.
   3
     There was some discussion amongst Reynolds and the Chapter regard-
ing an employment requirement that Reynolds solicit enough training
classes to be able to cover his salary. There is a dispute, however, as to
whether this requirement was, in fact, implemented, and, if so, the period
of time in which Reynolds would have had to meet the requirement. Reyn-
olds claims, "my understanding was that if that [the requirement] was
implemented, that I had a year from the date that I started that job to
accomplish that." J.A. at 496. Instead, Reynolds was terminated after only
six months of full time employment.
            REYNOLDS v. AMERICAN NATIONAL RED CROSS                      5
   On or about August 5 or 6, 2006, during the first week that
Reynolds worked as Manager of Service Delivery, Lockhart
instructed Reynolds to help move a baby grand piano from the
home of a donor to Lockhart’s personal residence. Lockhart
and Robert Clark, a member of the Chapter’s Executive Com-
mittee, also helped. Reynolds alleges that he experienced "se-
vere pain in both his neck and upper back" when he started
moving the piano. Am. Compl. ¶ 14.4 Clark testified, "when
we got into the process of moving the piano [Reynolds said,]
‘boy, my back really hurts’. So we say, ‘then don’t touch the
piano’." J.A. 703. Clark said he "strongly advised [Reynolds]
not to help." 

that Lockhart "ig-
nored [his] plea [to stop moving the piano] and required him
to continue assisting in delivering and unloading the piano to
his personal residence." Am. Compl. ¶ 15. Reynolds admitted
that prior to this incident, his back was "stiff and sore because
he had previously moved mattresses for the Chapter." J.A.
763.

  Reynolds alleges that after the piano incident he went to the
emergency room "a few days later . . . to seek relief from the
persistent and severe pain in his neck and upper back." Am.
Compl. ¶ 16.5 He saw two physicians, Dr. Boisverte and Dr.
Kribs, both in Lewisburg, who eventually referred him to Dr.
Dilaawar Mistry at the University of Virginia Health System
in Charlottesville. Because Reynolds’s car had been repos-
sessed and he had no other way to get to the appointment,
Lockhart drove Reynolds to Charlottesville to see Dr. Mistry
on September 7, 2006.
  4
    The Amended Complaint is found at J.A. 40-54.
  5
    During his deposition Reynolds admitted to going to the emergency
room on August 4, 2006, which was before the piano moving incident. For
the purpose of the Motion for Summary Judgment, however, Appellees
assumed that the alleged back injury was due to the piano lifting incident.
Therefore, this Court likewise makes that assumption for the purpose of
this appeal.
6         REYNOLDS v. AMERICAN NATIONAL RED CROSS
   Dr. Mistry examined Reynolds and noted he "complain[ed]
of persistent left arm pain." J.A. 116-17. The physical exami-
nation showed, however, "[n]ormal range of motion and
strength in flexion, extension and axial rotation of the neck.
Normal range of motion and strength of both shoulders,
elbows and wrists. There was mild sensory loss on the tip of
the index finger of the left hand compared to the right." 

Mistry also noted, in the "history" portion of the
report, that Reynolds’s X-ray showed "intervertebral disk
space narrowing with osteophytic change most pronounced at
C5-C6 and C6-C7" and "some foraminal encroachment sec-
ondary to osteophytes bilaterally." 

Mistry
scheduled an MRI to be performed in Charlottesville, made a
follow-up appointment on September 19, 2006, and gave
Reynolds a note stating that he could return to work "with
restrictions that include lifting weights only up to 15 pounds."

that due to Reynolds’s

    normal range of motion and strength of his shoul-
    ders, elbows and wrists, . . . [and] neck and
    flexion/extension, axial rotation, and his indication
    that he needs to return to work for the Red Cross, I
    felt as a clinician that up to 15 pounds would be rea-
    sonable to let him continue his work. . . .

the examination, Dr. Mistry said Reynolds had "no
physical limitations as far as range of motion" and he "would
[not] consider [Reynolds] disabled." J.A. 333. Reynolds never
returned to Charlottesville for his follow-up appointment or
MRI. Therefore, Dr. Mistry had no occasion to determine if
the fifteen-pound lifting restriction that he imposed was still
appropriate weeks later.

  Reynolds claims that after he returned to work, he was
asked to lift things in excess of fifteen pounds, despite Lock-
hart’s knowledge of Dr. Mistry’s orders. Upon their return to
            REYNOLDS v. AMERICAN NATIONAL RED CROSS                      7
Lewisburg, Lockhart "instructed [Reynolds] to assist with
moving boxes, mattresses, furniture and a five-drawer file
cabinet. [Reynolds] estimated that he lifted items weighing
more than fifteen pounds two to three times a week." J.A.
765, 533. Notably, however, Reynolds "never refused Lock-
hart’s instruction to lift any item while he was under the
restriction" and "could recall only one conversation when he
told Lockhart that he believed that moving a loaded file cabi-
net would be too heavy for him." 

   After allegedly sustaining the above-described back and
neck injuries,6 Reynolds twice told Lockhart he wanted to file
a workers’ compensation claim. Reynolds stated that Lockhart
told him that if he did so, "[he] would be dismissed and that
the Red Cross would fight [the claim]." 

also told him the Chapter’s Executive Committee "[isn’t]
going to let you do that," and a workers’ compensation claim
"would cost the chapter either one or one-and-a-half percent
rate increase hike" and the Chapter "wouldn’t stand for that."

   At some point before the end of 2006, the Chapter deter-
mined that it no longer had the funds to pay Reynolds, and
Reynolds was so advised. Then, on or around January 28,
2007, Lockhart verbally informed Reynolds that he was ter-
minated because the Chapter did not have the funds to pay
him. On January 30, 2007, Reynolds received a termination
letter from Lockhart stating, "[d]ue to budget restriction [sic]
the Board of Director [sic] has asked me to termination [sic]
your employment with this chapter as of today." The letter
continued,
  6
    Reynolds also claims that he was disabled because he had "a blood dis-
order" which led to erectile dysfunction, but offered no medical support
in the record for this allegation nor any indication as to how this alleged
disorder rendered him disabled. Br. of Appellant 26-27.
8           REYNOLDS v. AMERICAN NATIONAL RED CROSS
    We are exercising our rights as an "at will
    employer." As you know this had been the balance
    for the last ninety day [sic], hoping you would gener-
    ate enough income to cover your salary. This has not
    been done. Also the single family files has [sic] not
    been entered into the CAS system, since July 2006.
    Only about fifty percent of the Instructor [sic] in
    health and safety has been upgraded.

J.A. 120.

   As noted, there is some dispute as to whether Reynolds was
required to bring in enough money to cover his salary as a
part of his employment. It is undisputed that Reynolds did not
receive any negative evaluations or reprimands related to his
job performance prior to his termination.

                              C.

   After his termination from the Chapter, Reynolds applied
for and was denied West Virginia workers’ compensation
benefits for his alleged back and neck injuries because his
application was untimely. He then filed a disability discrimi-
nation charge against the Chapter with the Equal Opportunity
Employment Commission ("EEOC") based on those alleged
injuries. He claimed that he was "harassed, retaliated against,
treated differently from others, denied a reasonable accommo-
dation, and unlawfully discharged based on his disability."
J.A. 768.

   In March 2008, Reynolds obtained a teaching position in
North Carolina. He earned $43,000 per year, plus full bene-
fits. While at that job, Reynolds moved 195 books on a book
cart down a ramp. He tried to push the cart in front of him,
but it was "extremely heavy," so he tried to get in front of the
cart. The cart "got away from [him]" and "basically ran [him]
over." J.A. 442-43. After that incident, Reynolds filed for
worker’s compensation benefits, and he has been receiving
           REYNOLDS v. AMERICAN NATIONAL RED CROSS           9
those benefits from the state of North Carolina since August
21, 2008.

   On December 30, 2009, the EEOC determined that the
Chapter was not an ADA covered employer and dismissed
Reynolds’s EEOC claim. Reynolds then filed this action in
district court.

   Appellees filed a motion for summary judgment, arguing
Reynolds did not present sufficient evidence to prove he was
disabled and, in any event, the Chapter was not an "employer"
under the ADA. The district court ruled in favor of Appellees
as to the former but against Appellees on the latter. It held
that, even though the Chapter employed fewer than fifteen
people—the threshold number of employees required to
invoke the ADA—the Chapter nonetheless was an "agent" of
the American National Red Cross, a covered employer under
the ADA. See Reynolds v. Am. Nat’l Red Cross, No. 5:10-cv-
00443 (S.D. W. Va. Oct. 17, 2011), ECF No. 88.7 Reynolds
filed a timely appeal, and Appellees filed a cross-appeal on
the agency issue alone.

                                   II.

   We review the district court’s summary judgment ruling de
novo, applying the same standard applied by the district court.
See Henry v. Purnell, 

, 531 (4th Cir. 2011); Med.
Waste Assocs. Ltd. v. Mayor & City Council of Baltimore, 

, 150 (4th Cir. 1992). Summary judgment is appro-
priate when there is no genuine issue of material fact, and the
moving party is entitled to summary judgment as a matter of
law. 

for summary judgment, "facts must be
viewed in the light most favorable to the nonmoving party
only if there is a genuine dispute as to those facts." Ricci v.

   The district court’s opinion is found at J.A. 761-94.
10        REYNOLDS v. AMERICAN NATIONAL RED CROSS
                              III.

   The ADA provides, "[n]o covered entity shall discriminate
against a qualified individual on the basis of disability in
regard to job application procedures, the hiring, advancement,
or discharge of employees, employee compensation, job train-
ing, and other terms, conditions, and privileges of employ-
ment." 42 U.S.C. § 12112(a). "Covered entity" is defined as
"an employer, employment agency, labor organization, or
joint labor-management committee." 

ployer" is defined as "a person engaged in an industry affect-
ing commerce who has 15 or more employees . . . , and any
agent of such person[.]" 

  The Appeal

  Reynolds appeals three ADA claims on which the district
court awarded summary judgment: (1) he was fired because
of his alleged disability (the "primary ADA claim"); (2) he
was retaliated against for engaging in protected activities
under the ADA (the "retaliation claim"); and (3) his employer
shared confidential medical information about his alleged dis-
ability (the "confidentiality claim"). We address each in turn
below.

                1.   The Primary ADA Claim

   To survive summary judgment on the primary ADA claim,
Reynolds was required to produce evidence sufficient to dem-
onstrate that (1) he "was a qualified individual with a disabil-
ity"; (2) he "was discharged"; (3) he "was fulfilling h[is]
employer’s legitimate expectations at the time of discharge";
and (4) "the circumstances of h[is] discharge raise a reason-
able inference of unlawful discrimination." Rohan v. Net-
works Presentations LLC, 

, 273 n.9 (4th Cir.
2004) (internal quotation marks omitted). Evidence of all four
of these elements is necessary to survive summary judgment.
Reynolds’ claim fails at step one.
          REYNOLDS v. AMERICAN NATIONAL RED CROSS              11
   Reynolds was first required "to produce evidence that [he]
is . . . disabled." 

. The ADA defines
disability as any one of the following: "(A) a physical or men-
tal impairment that substantially limits one or more . . . major
life activities . . . ; (B) a record of such an impairment; or (C)
being regarded as having such an impairment." 42 U.S.C.
§ 12102(2); see also 

. As explained
below, because Reynolds does not produce sufficient evi-
dence to satisfy this element of the claim, we need not go fur-
ther.

                                a.

   Given that Reynolds’s alleged disability occurred in 2006,
in deciding whether Reynolds produced sufficient evidence of
a disability, we must first decide whether to apply retroac-
tively the ADA Amendments Act of 2008 (the "ADAAA"),
which took effect January 1, 2009. See ADAAA, Pub. L. No.
110-325, § 8; 122 Stat. 3553, 3553 (Sept. 25, 2008).

   In passing the ADAAA, Congress was concerned "lower
courts have incorrectly found in individual cases that people
with a range of substantially limiting impairments are not
people with disabilities." 122 Stat. at 3553. Congress believed
that over time, ADA case law "eliminate[d] protection for
many individuals whom Congress intended to protect." 

of the ADAAA, courts relied upon
Toyota Motor Manufacturing, Kentucky, Inc. v. Williams, 

(2002), and Sutton v. United Air Lines, Inc., 

(1999), in determining whether a plaintiff was dis-
abled. These cases defined the terms "substantially" and
"major," as used in the ADA definition of disability, "to be
interpreted strictly to create a demanding standard for qualify-
ing as disabled[.]" 

.

  The Toyota Court held, in order to qualify as disabled
under the ADA, "an individual must have an impairment that
12         REYNOLDS v. AMERICAN NATIONAL RED CROSS
prevents or severely restricts the individual from doing activi-
ties that are of central importance to most people’s daily lives.
The impairment’s impact must also be permanent or long

. The Court continued,

      It is insufficient for individuals attempting to prove
      disability status under this test to merely submit evi-
      dence of a medical diagnosis of an impairment.
      Instead, the ADA requires those claiming the Act’s
      protection . . . to prove a disability by offering evi-
      dence that the extent of the limitation [caused by
      their impairment] in terms of their own experience
      . . . is substantial.

Id.; see also 

("A ‘disability’ exists
only where an impairment ‘substantially limits’ a major life
activity, not where it ‘might,’ ‘could,’ or ‘would’ be substan-
tially limiting if mitigating measures were not taken.").

   The district court decided — as have eight circuits—that
the ADAAA does not apply retroactively and instead, relied
on Toyota and Sutton in ruling on Reynolds’ claim. See Car-
ter v. Pathfinder Energy Servs., 

, 1144 (10th
Cir. 2011) (declining to impose the ADAAA retroactively);
Nyrop v. Indep. Sch. Dist. No. 11, 

, 734 n.4 (8th
Cir. 2010) (same); Becerril v. Pima Cnty. Assessor’s Office,

, 1164 (9th Cir. 2009) (same); Thornton v.
United Parcel Serv., Inc., 

, 35 n.3 (1st Cir. 2009)
(same); Fredricksen v. United Parcel Serv. Co., 

,
521 n.1 (7th Cir. 2009) (same); Lytes v. D.C. Water & Sewer
Auth.,

v. Sumner Cnty. Bd. of Educ., 

, 565 (6th Cir.
2009) (same); EEOC v. Agro Distribution LLC, 

,
469 n.8 (5th Cir. 2009) (same).8

   This court has also held the same in an unpublished opinion. See Coch-
ran v. Holder, 436 F. App’x 227 (4th Cir. June 21, 2011).
          REYNOLDS v. AMERICAN NATIONAL RED CROSS             13
   The Supreme Court has held, "[R]etroactivity is not favored
in the law[.] [C]ongressional enactments and administrative
rules will not be construed to have retroactive effect unless
their language requires this result." Landgraf v. Usi Film
Prods., 

, 264 (1994). The ADAAA itself pro-
vides "[t]his Act and the amendment made by this Act shall
become effective on January 1, 2009." 122 Stat. at 3559. In
Cochran, this court concluded that the amendment "evinces a
prospective intent with its delayed effective date." 436 F.
App’x at 232. We agree: there is no language in the ADAAA
indicating that Congress intended to make this law retroac-
tive; in fact, the indication is to the contrary.

   Reynolds nonetheless contends that although the ADAAA
was not in effect at the time the conduct giving rise to this
case occurred, it was in full effect when the district court ren-
dered its decision below (October 17, 2011), and it should be
applied for that reason. See 

("[I]n
many situations, a court should apply the law in effect at the
time it renders its decision, even though that law was enacted
after the events that gave rise to the suit." (internal citations
and quotation marks omitted)). But Landgraf resolved,

    [P]rospectivity remains the appropriate default rule.
    Because it accords with widely held intuitions about
    how statutes ordinarily operate, a presumption
    against retroactivity will generally coincide with leg-
    islative and public expectations. Requiring clear
    intent assures that Congress itself has affirmatively
    considered the potential unfairness of retroactive
    application and determined that it is an acceptable
    price to pay for the countervailing benefits. Such a
    requirement allocates to Congress responsibility for
    fundamental policy judgments concerning the proper
    temporal reach of statutes, and has the additional vir-
    tue of giving legislators a predictable background
    rule against which to legislate.
14        REYNOLDS v. AMERICAN NATIONAL RED 

; see also 

(declin-
ing to apply the ADAAA retroactively because it went into
effect after "the allegedly discriminatory conduct in this case
occurred"); 

n.3 (explaining that the
ADAAA does not apply retroactively to "conduct occurring
before the Act became effective").

  For these reasons, we join the majority of the circuits in
deciding the ADAAA does not apply retroactively. Therefore,
we will instead look to Toyota, Sutton, and their progeny.

                                b.

   We first consider whether Reynolds provided evidence on
the first ADA definition of disability: whether he had a physi-
cal impairment that substantially limited one or more major
life activities. See 42 U.S.C. § 12102(2)(A). Reynolds primar-
ily cites "lifting" as the major life activity in which he is sub-
stantially limited due to his alleged back and neck injuries.
Federal regulations have established that lifting is a major life
activity, see 29 C.F.R. § 1630.2(i)(1), but Reynolds fails to
show how he has been "substantially limited" in this regard.
Reynolds has not shown that his alleged injuries have "pre-
vent[ed] or severely restrict[ed]" him "from doing activities
that are of central importance to most people’s daily lives."

. He has also not shown any evidence
that these injuries are "permanent or long term." 

evidence is to the contrary. Reynolds continued
to lift things upon his return to work; he did not return to Dr.
Mistry (or to any doctor) for a determination that his lifting
restriction of fifteen pounds should be permanent; and even at
his new job in North Carolina, he took on the task of trans-
porting 195 books, which signals that he did not believe him-
self to be limited in the activity of lifting. Moreover, the only
medical evidence Reynolds provides regarding his alleged
limitation is a three-page medical report from Dr. Mistry.
Coupled with Dr. Mistry’s testimony that he did not believe
            REYNOLDS v. AMERICAN NATIONAL RED CROSS                     15
Reynolds to be disabled, this evidence does not demonstrate
that Reynolds was substantially limited in the life activity of
lifting.

   Reynolds’s argument is further undercut by this court’s
decision in Williams v. Channel Master Satellite Sys., Inc.,

(4th Cir. 1996), abrogated on other grounds by
Baird ex rel. Baird v. Rose, 

, 470 (4th Cir. 1999).
There, this court held, "a twenty-five pound lifting limitation
—particularly when compared to an average person’s abilities
—does not constitute a significant restriction on one’s ability
to lift, work, or perform any other major life activity." 

2002, this court again found that "mild limitations"
such as "the restriction[ ] that [the plaintiff] not lift more than
twenty-five pounds or bend repetitively . . . are not signifi-
cantly restricting . . . under the ADA." Pollard v. High’s of
Baltimore, Inc., 

, 470 (4th Cir. 2002); see also
Colwell v. Suffolk Cnty. Police Dep’t, 

, 639, 644
(2d Cir. 1998) (inability to lift "very heavy objects" or "any-
thing heavy" was insufficient to establish a substantial limita-
tion on ability to lift as compared to the average person);
Snow v. Ridgeview Med. Ctr., 

, 1207 (8th Cir.
1997) ("While lifting is noted under the regulations as a major
life activity, a general lifting restriction imposed by a physi-
cian, without more, is insufficient to constitute a disability
within the meaning of the ADA."). Therefore, Reynolds has
not satisfied the first definition of "disabled" under the ADA.9

                                    c.

  We next address whether Reynolds has satisfied the second
definition of disability: having "a record of" a physical
impairment that substantially limits one or more major life
  9
    To the extent Reynolds cites other disabilities (i.e., a blood disorder
leading to erectile dysfunction) and other life activities in which he was
limited (i.e., working), the record is void of any evidence to support ADA
claims based on such allegations.
16        REYNOLDS v. AMERICAN NATIONAL RED CROSS
activities. 42 U.S.C. § 12102(2)(B). On this point, Reynolds
bends over backwards to argue that he has provided "a
record"—that is, literally one medical record—and this should
be sufficient to satisfy this requirement.

   However, under the applicable definition, we must consider
if Reynolds has "a history of, or has been misclassified as
having, a . . . physical impairment that substantially limits one
or more major life activities." 

(inter-
nal quotation marks omitted). Reynolds’s single proffered
medical report is, at best, inconclusive as to the history and
extent of his alleged disability, despite the fact that he alludes
to "voluminous [medical] records," particularly when this sin-
gle medical record is coupled with the fact that the doctor
who wrote it, Dr. Mistry, testified that he did not believe
Reynolds to be disabled. Br. of Appellant 30. Indeed, Reyn-
olds admits he did not provide all relevant medical informa-
tion, stating,

     It is true that all of the records of Mr. Reynolds’
     entire medical history were not included as exhibits
     in his response to summary judgment below. How-
     ever, the presentment of these voluminous records is
     unnecessary for purposes of this analysis. It is not
     the substance of these records that is significant in
     order to reach a decision under this second prong of
     the ADA’s definition of a disability. Instead, it is the
     existence of these records that is consequential here,
     and the existence of these records is undisputed.

Contrary to Reynolds’s bold asser-
tion, unless the purported medical records were placed in the
record — which they admittedly were not — they do not, in
fact, exist for the purpose of this appeal. Therefore, by his
admission, Reynolds acknowledges that he failed to satisfy
his burden of production. See Ricci v. DeStefano, 

, 586 (2009) ("[W]here the nonmoving party will bear the
burden of proof at trial on a dispositive issue, the nonmoving
            REYNOLDS v. AMERICAN NATIONAL RED CROSS                      17
party bears the burden of production under Rule 56 to desig-
nate specific facts showing that there is a genuine issue for
trial." (internal quotation marks omitted)). We therefore con-
clude Reynolds does not satisfy the second definition of dis-
ability.

                                    d.

   Finally, Reynolds argues he was, at least, "regarded as"
having a physical impairment that substantially limited one or
more major life activities, thus satisfying the third definition
of disability. 42 U.S.C. § 12102(2)(C). Reynolds must show
that his employer "mistakenly believe[d] that [he] ha[d] a
physical impairment that substantially limit[ed]" his ability to
lift or work. 

. To the contrary, Lock-
hart expected Reynolds to continue lifting things at work, and
Reynolds continued to do so. Lockhart testified that Reynolds
had complained of back pain and his blood disorder through-
out the time he knew him, but there is no further evidence
Lockhart believed these conditions substantially limited
Reynolds’s ability to lift or work. Reynolds also points to tes-
timony from Clark, specifically that he told Reynolds not to
move the baby grand piano because of his back pain. But this
statement is nothing more than one of concern for a co-
worker, which is simply not enough to satisfy this definition
of disability.

   Therefore, Reynolds comes up short on each of the three
ADA definitions of disability, and we affirm the judgment of
the district court with regard to the primary ADA claim.10
    10
       Even if we were obliged to apply the ADAAA to the facts of this case,
Reynolds has not proven that he is disabled under its broader definition of
"disability." The ADAAA retains the "substantial limitation" language, but
it requires a lesser "degree of limitation" than that imposed by Toyota. 122
Stat. at 3553-54. "Substantially limits" no longer means "significantly
restricted." 

the revisions are somewhat vague, any
findings of disability should be interpreted "consistently with the findings
18          REYNOLDS v. AMERICAN NATIONAL RED CROSS
                    2.    The Retaliation Claim

   Reynolds also claims he was terminated by Lockhart and
the Chapter in retaliation for (a) requesting that he not be
required to lift items exceeding fifteen pounds in weight, and
(b) mentioning that he wanted to file a workers’ compensation
claim.

   The ADA’s retaliation provision provides, in relevant part,
"[n]o person shall discriminate against any individual because
such individual . . . made a charge . . . under this chapter." 42
U.S.C. § 12203(a). To establish a prima facie retaliation claim
under the ADA, a plaintiff must prove (1) he engaged in pro-
tected conduct, (2) he suffered an adverse action, and (3) a
causal link exists between the protected conduct and the
adverse action. See A Soc’y Without a Name v. Common-
wealth of Va., 

, 350 (4th Cir. 2011). Importantly,
a plaintiff is not required to prove the conduct he opposed was
actually an ADA violation. Rather, he must show he had a
"good faith belief" the conduct violated the ADA. Freilich v.
Upper Chesapeake Health, 

, 216 (4th Cir. 2002)
(internal citations omitted).

   As to Reynolds’s first grounds for retaliation, his alleged
protected conduct is his request that Lockhart honor the
fifteen-pound lifting restriction imposed by Dr. Mistry. He
claims Lockhart nonetheless required him to move items in
excess of the limitation. Even assuming that Reynolds met the
first two prongs to establish a prima facie claim of retaliation,
as the district court observed, Reynolds "has not proffered any
. . . citation to the record demonstrating that there is ‘evi-

and purposes of the ADA Amendments Act of 2008" which include
"eliminat[ing] discrimination" of disabled persons. 

on the record before us, and for the reasons 

, Reynolds does
not advance evidence sufficient to show that he is disabled or is the type
of plaintiff intended to be covered under the original version of the ADA
or under the ADAAA.
          REYNOLDS v. AMERICAN NATIONAL RED CROSS            19
dence’ of a link between the protected activity and his termi-
nation . . . ." J.A. 792. On appeal, Reynolds has similarly
failed to cite to any evidence on the causation element of the
ADA retaliation claim. Therefore, the retaliation claim based
on Reynolds’s lifting restriction fails.

   The retaliation claim based on Reynolds’s workers’ com-
pensation inquiry also fails. The ADA’s retaliation provision
only prohibits retaliation against a person because the person
"opposed any act or practice made unlawful by this chapter"
or "made a charge, testified, assisted or participated in any
manner in an investigation, proceeding, or hearing under this
chapter." 42 U.S.C. § 12203(a) (emphases added). Filing a
workers’ compensation claim is not something that is covered
by the ADA, but rather by retaliation provisions under state
law. See W. Va. Code § 23-5A-1 ("No employer shall dis-
criminate in any manner against any of his present or former
employees because of such present or former employee’s
receipt of or attempt to receive benefits under this chapter.").
Thus, Reynolds’s retaliation claim based on his workers’
compensation request likewise fails.

               3.   The Confidentiality Claim

   Finally, Reynolds argues, "information obtained regarding
the medical condition or history [of an employee must be]
collected and maintained on separate forms and in separate
medical files and is treated as a confidential medical record."
Br. of Appellant 33 (citing 42 U.S.C. § 12112(d)(3)(B))
(alteration in original). He argues that Lockhart violated this
provision of the ADA by disclosing his "thick blood" medical
condition to "unauthorized individuals." 

Reynolds does not have the evidence to support this
claim. First, Reynolds does not fit within the parameters of
this subsection, which applies to "job applicant[s]." 42 U.S.C.
§ 12112(d)(3). But even assuming Reynolds had cited to the
more applicable subsection, which prohibits "mak[ing] [medi-
20        REYNOLDS v. AMERICAN NATIONAL RED CROSS
cal] inquiries of an employee," 

record clearly shows Reynolds disclosed his medical condi-
tion voluntarily to Lockhart, who by all accounts was Reyn-
olds’s friend. Lockhart then disclosed the information to
another person in order to help Reynolds find a doctor, not for
"job-related" purposes. 

court prop-
erly granted summary judgment on this issue.

                    B.   The Cross-Appeal

   We turn finally to the cross-appeal of the Appellees, where
they assert the Chapter and the National Red Cross could not
be aggregated in order to meet the fifteen employee threshold
required for an "employer" under the ADA. As an initial mat-
ter, we are satisfied that the issue of whether the Chapter is
an "employer" under the ADA is non-jurisdictional in nature.
Previously, we treated the numerosity requirements of the
ADA and other employment discrimination statutes as juris-
dictional. See Hukill v. Auto Care, Inc., 

(4th Cir.
1999) (vacating district court’s judgment and remanding with
instructions to dismiss for lack of jurisdiction where defen-
dant was not an "employer"). However, this approach does
not survive Arbaugh v. Y&H Corp., 

(2006).
There, the Supreme Court ruled "the threshold number of
employees for application of Title VII is an element of a
plaintiff’s claim for relief, not a jurisdictional issue." 

we have never applied Arbaugh to the ADA,
courts often look to Title VII—which defines "employer" in
essentially the same way as the ADA—for guidance on ADA
issues. Compare 42 U.S.C. § 12111(5)(a) with 42 U.S.C.
§ 2000e(b); see also Swallows v. Barnes & Noble Book
Stores, Inc., 

, 992 n.2 (6th Cir. 1997) ("Because
Title VII, the ADEA, and the ADA define ‘employer’ essen-
tially the same way, we rely on case law developed under all
three statutes." (internal quotation marks omitted)); EEOC v.
AIC Sec. Investigations, 

, 1280 (7th Cir. 1995)
          REYNOLDS v. AMERICAN NATIONAL RED CROSS            21
("Courts routinely apply arguments regarding individual lia-
bility to all three statutes interchangeably."). Thus, Arbaugh
dictates that the ADA’s employee threshold is not a limit on
jurisdiction but, rather, an element of the claim itself.

   Next, we conclude that the cross-appeal was not properly
taken. A cross-appeal is unnecessary where an appellee
"seek[s] nothing more than to preserve [a] judgment in [its]
favor." Vogel v. Linde, 

, 79 n.3 (4th Cir. 1994); see
also Nat’l Union Fire Ins. Co. of Pittsburgh, Pa. v. W. Lake
Acad., 

, 23 (1st Cir. 2008) ("‘A cross-appeal nor-
mally is improper when taken by a defendant from a favorable
judgment.’") (quoting United States v. Moran, 

, 12
(1st Cir. 2004)). Here, the cross-appeal on whether the Chap-
ter is an "employer" is unnecessary, as it merely seeks affir-
mance of the district court’s judgment on an alternate ground.
Therefore, the cross-appeal must be dismissed. See Nat’l

(dismissing cross-appeal from a favor-
able judgment).

   Finally, we vacate the district court’s ruling on the
employee aggregation issue. Our decision to uphold the dis-
trict court’s grant of summary judgment on the merits of the
ADA claim renders moot the dispute concerning whether the
Chapter is an "employer." This is because, having affirmed
the district court’s judgment, our resolution of the question of
whether the Chapter is an "employer" would have no practical
effect on the outcome of this matter. See Norfolk S. Ry Co. v.
City Of Alexandria, 

, 161 (4th Cir. 2010) ("A
dispute is moot when the parties lack a legally cognizable
interest in the outcome. And the parties lack such an interest
when, for example, our resolution of an issue could not possi-
bly have any practical effect on the outcome of the matter.")
(internal citations and quotation marks omitted). "The cus-
tomary practice when a case is rendered moot on appeal is to
vacate the moot aspects of the lower court’s judgment." 

court’s ruling that the Chapter is an
"employer" under the ADA must be vacated.

                             IV.

  Pursuant to the foregoing, the district court’s award of sum-
mary judgment to Appellees is affirmed, its ruling that the
Chapter is an "employer" under the ADA is vacated, and the
cross-appeal is dismissed.
