*780 OPINION OF THE COURT
Jоseph A. Mondzelewski (“Mondzelewski”) and his wife, Rebecca Mondzelewski, sued Pathmark Stores, Inc., and Supermarkets General Corp. (collectively, “Pathmark”), asserting claims under the Americans with Disabilities Act of 1990, 42 U.S.C. § 12101 et seq. (the “ADA”), and Delaware law. The District Court granted summary judgment for Pathmark and declined to exercise supplemental jurisdiction on the state-law claims. On appeal, Mondzelewski argues that the District Court erred in holding that he is not disabled within the meaning of the ADA because he is not substantially limited in the major life activity of working. In addition, relying on
Krouse v. American Sterilizer Co.,
I.
A. Viewed in the light most favorable to Mondzelewski, the relevant facts are as follows. Mondzelewski, a 55-year old with a sixth-grade education, has worked at Path-mark for 35 years, first as a bagger and then as a meat cutter. In March 1992, he injured his back lifting boxes of meat and was treated by Dr. Henry, Pathmark’s doctor, who diagnosed him as having a herniated vertebral disc. After Mondzelewski spent a short time on disability, Dr. Henry released him to work but restricted him from lifting objects weighing more than 50 pounds and from carrying objects weighing more than 25 pounds. Mondzelewski informed Pathmark of his lifting restrictions.
In December 1993, Mondzelewski re-injured his bаck while lifting boxes of meat. After a few additional months on disability, Mondzelewski was again released to work with the same lifting restrictions, and he again provided a copy of the restrictions to Pathmark.
Mondzelewski claims that, after returning to work from his second injury, Pathmark retaliated against him for asserting his right under the ADA to obtain reasonable accommodation for a disability. See 42 U.S.C. § 12112(b)(5)(A). Mondzelewski first maintains that Pathmark unlawfully changed his work schedule. In Pathmark’s meat department, workers were generally given schedules that allowed them free time in either the mornings or the afternoons. Some workers began their shifts between 6 and 8 a.m. and finished by 2 p.m., while others began at noon and worked until evening. In addition, workers genеrally were not required to work in the evening on weekends on a regular basis. Before his second injury, Mondzelew-ski’s schedule generally followed this pattern, but after his second injury, Pathmark assigned him to work from 9:30 a.m. to 6:00 p.m. and consistently required him to work on Saturday evenings. According to Mond-zelewski and his fellow workers, these shifts were considered “punishment shifts.” App. 122-125.
Mondzelewski also contends that he was given several retaliatory reprimands. First, Mondzelewski stated in his deposition that he received an oral warning for taking his work break during the last hour of his shift and that no other employees were given such warnings. Second, Mondzelewski was given a written notice of counseling because he had “left ground beef in [the] cаse” instead of making “frozen patties” or “consult[ing] management for direction.” App. 138. Mondze-lewski described this notice as one for grinding up too much meat, and he asserted that it was not unusual for employees to grind up more meat than could be sold. App. 81-82. Although this notice stated that it was for “counseling only,” it also stated that “future violations will result in additional disciplinary action including separation.” App. 138. Mondzelewski claims that this was the first written reprimand he had ever received during his 35-year career at Pathmark.
Last, within a week of the earlier written notice, Mondzelewski received another written notice for “insubordination” for refusing *781 to lift a piece of meat. The meat was unmarked as to its weight, but Mondzelewski estimated it to weigh between 50 and 100 pounds. Because his co-worker refused to assist in lifting the meat, Mondzelewski called on a department manager for help. Instead of offering assistance, Mondzelewski claims the department manager wrote specific weights on this and other pieces of meat without actually weighing them. The department manager then allegedly told Mondze-lewski to lift the meat stating: “You want to play those[expletive] games, well, I’m not. You want a write up. I’m telling you to do these chucks. You either do it or you go home.” App. 45. Mondzelewski refused, and as a result, he was written up and suspended for the afternoon. Like his previous written notice, this notiсe stated that “future violations will result in additional disciplinary action including separation.” App. 139. At a grievance meeting to discuss the matter, Mondzelewski was told, he asserts, that his restrictions were disrupting the work of his fellow employees.
Mondzelewski asserts that on one occasion his supervisor refused to give him time off for a medical test and told him he would have to reschedule it. He also stated that on some occasions the department manager refused his request for help in lifting meat and said: “Things are not that heavy. You can pick that up.” App. 48.
Finally, Mondzelewski claims that Path-mark’s managers and employees harassed and humiliated him. Mondzelewski was sent to a worker’s compеnsation seminar at which a speaker said that some employees fake accidents. On another occasion, he states, he was not given a' “butcher’s white coat” and was told it was because he would not be around much longer. At another time, he was allegedly told that Pathmark should release him and find him a job pumping gas. Moreover, he stated that he was told: “We don’t need a meat cutter. We don’t need a wrapper, and we don’t need you.” App. 83. Further, Mondzelewski asserts that a manager made a derogatory and offensive hand gesture to his wife and him.
Mondzelewski claims that Pathmark’s conduct caused him to suffer a mental breakdown and to miss work for several months. During this period, he filed a charge against Pathmark with the Equal Employment Opportunity Commission (“EEOC”). Later that year, he returned to work, but he was assigned to a different store in order to prevent any further acts of retaliation. At present, Mondzelewski continues to work at Pathmark, and according to him, the harassment has ended. However, he states that he continues to require medication and psychological counseling.
B. Mondzelewski filed a six-count complaint in the United States District Court for the District of Delaware. Count I alleged that Pathmark discriminated against him, in violation of 42 U.S.C. § 12112, by failing to provide reasonable accommodation for his lifting restrictions. Count II claimed that Pathmark violated 42 U.S.C. § 12203 by retaliating against him for rеquesting a reasonable accommodation when he returned to work after his second injury. Count III asserted that Pathmark violated a Delaware statute, 19 Del.Code § 2365, by retaliating against him for filing a worker’s compensation claim. Counts IV and V alleged common law torts, and Count VI asserted injury to the Mondzelewskis’ marital relationship.
The District Court granted summary judgment for Pathmark on the federal claims.
See Mondzelewski v. Pathmark Stores, Inc.,
Turning to Mondzelewski’s retaliation claim, the Court held that “Mondzelewski may not assert a claim for retaliation because he is not disabled.”
Mondzelewski,
Despite such precedent, the Court does not hold that the acts alleged by Mondzelewski do not, as a matter of law, constitute adverse employment action, although it does not believe it would be error to do so. For example, Mondzelewski’s most tangible complaint — the change in shifts — must be discounted because of the common sense notion that a 9:00 a.m. to 5:00 p.m. shift cannot be considered an extreme hardship given most of this country’s workers are governed by that shift.
Mondzelewski,
In this appeal, we must decide (1) whether the District Court correctly concluded that Mondzelewski is not disabled within the meaning of the ADA and (2) whether a claim for retaliation can be asserted even if the underlying disability claim fails. In addition, since the District Court stated that it would not be error to hold that Mondzelewski had not suffered any “adverse employment action,” we will address that question as well.
II.
We turn first to the District Court’s conclusion that Mondzelewski is not disabled within the meaning of the ADA. Mondzelew-ski does not challenge the District Court’s holding that he is not substantially limited in the major life activity of lifting, but he contends that the District Court erred in granting summary judgment against him on the question whether his back impairment, coupled with his limited education, training, and skills, substantially limits his ability to work. We agree.
A. The ADA prohibits an employer from discriminating against a qualified individual with a disability because of the disability, 42 U.S.C. § 12101, and as noted, the term “disability” is defined to mean, among other things, “a physical ... impairment that substantially limits one or morе of the major life activities of such individual.” 42 U.S.C. § 12102(2)(A). 1 Pathmark does not dispute that Mondzelewski’s back injury is a “physical impairment,” but Pathmark argues that this impairment does not substantially limit any major life activity.
Although the ADA does not define the term “substantially limits,” the EEOC regulations provide guidance. See 42 U.S.C. § 12116 (empowering the EEOC to promulgate regulations implementing the ADA);
Deane v. Pocono Medical Ctr.,
According to the regulations, “working” is a “major life activity.” 29 C.F.R. § 1630.2(f).
2
The regulations state that an individual is substantially limited in the major life activity of working if there is a significant restriction in the ability “to perform either a class of jobs or a broad range of jobs in various classes as compared to the average person having comparable training, skills and abilities.” 29 C.F.R. § 1630.2(j)(3)(i). When analyzing whether there has been a substantial limitation on the major life activity of working, the regulations provide that the courts may also consider: (1) the geographical area to which the individual has reasonable access; (2) the job from which the individual has been disqualified, and the number and types of jobs utilizing similar training, knowledge, skills or abilities from which the individual is also disqualified (“class of jobs”); and/or (3) the job from which the individual has been disqualified, and the number and types of other jobs not utilizing similar training, knowledge, skills or abilities from which the individual is also disqualified (“broad range of jobs”). 29 C.F.R. § 1630.2(j)(3)(ii);
see also Deane,
On Pathmark’s motion for summary judgment, the District Court held that Mondze-lewski had not provided sufficient evidence to demonstrate that he is substantially limited in the major life activity of working.
Mondzelewski,
B. The District Court concluded that, “while Mondzelewski’s employability problems stem from a combination of factors— limited education, limited job skills, advanced age, and lifting restrictions — the first three of these factors dwarf the.last one in effect on employability.” Id. The Court stressed that “[t]o hold Mondzelewski is substantially limited in the major life activity оf work would permit him to gain protection from the ADA for personal characteristics that have nothing to do with his impairment.” Id. We conclude that the District Court’s legal analysis was flawed because, as the ADA regulations explicitly provide, a court should consider the individual’s “training, skills and abilities” in determining whether the individual is substantially limited in the major life activity of working. 29 C.F.R. § 1630.2(j)(3)(i).
Under the EEOC’s interpretive guidelines, 3 determining whether an individual is substantially limited in one or more of the major life activities requires a two-step analysis. First, the court determines whether the individual is substantially limited in any major life activity other than working, such as walking, seeing, or hearing. 29 C.F.R. Pt. 1630, App. § 1630.2(j). In making this determination, the court compares the effect of the impairment on that individual as comparеd with the “average person in the general population.” 29 C.F.R. § 1630.2(j)(l); 29 C.F.R. Pt. 1630, App. § 1630.2(j) (stating that the determination must be conducted on a case by case basis). For example, “an individual who had once been able to walk at an extraordinary speed would not be substantially limited in the major life activity of walking if, as a result of a *784 physical impairment, he or she were only able to walk at an average speed, or even at a moderately below average speed.” 29 C.F.R. Pt. 1630, App. § 1630.20'). If the court finds that the individual is substantially limited in any of these major life activities, the inquiry ends there. Id. On the other hand, if the individual is not so limited, the court’s next step is to determine whether the individual is substantially limited in the major life activity of working. 4 Id.
In determining whether an individual is substantially limited in the ability to work, the proper inquiry, according to the relevant regulation, is whether the individual is “significantly restricted in the ability to perform either a class of jobs or a broad range of jobs in various classes
as compared to the average person having comparable training, skills and abilities.”
29 C.F.R. § 1630.2(j)(3)(i) (emphasis added). This approach requires a court to consider the individual’s training, skills, and abilities in order to evaluate “whether the particular impairment constitutes for the particular person a significant barrier to employment.”
Webb v. Garelick Mfg. Co.,
We accept this approach — under which an individual’s training, skills, and abilities are taken into account in determining whether the individual is substantially limited in the major life activity of working — because we owe “substantial deference” to the EEOC regulation in which it is set out,
see Deane,
C. Under the approach set out above, the District Court in the present case was required to determine whether Mondzelewski’s evidence was sufficient to show that his lifting restrictions significantly limit his ability to perform the requisite jobs “as compared to the average person having comparable training, skills and abilities.” 29 C.F.R. § 1630.2(j)(3)(i). This determination necessitated consideration of the “personal characteristics” that the District Court’s analysis factored out. Whether Mondzelewski’s lifting restriction would not limit him in the *785 major life activity of working if he possessed more or different training, skills, or abilities is not determinative; rather, the question is whether his ability to work is sufficiently limited in light of the training, skills, аnd abilities that he does possess.
In finding that Mondzelewski is not disabled, the District Court mistakenly relied on a provision in the EEOC guidelines that states:
[T]he restriction on the performance of the major life activity must be the result of a condition that is an impairment_ [Advanced age, physical or personality characteristics, and environmental, cultural, and economic disadvantages are not impairments. Consequently, even if such factors substantially limit an individual’s ability to perform a major life activity, this limitation will not constitute a disability.
29 C.F.R. Pt. 1630, App. § 1630.2®. By its plain language, this provision relates to the question whether the individual has a physical or mental impairment, not whether the, impairment substantially limits a major life activity and thus constitutes a disability. The guideline provides the following example:
[A]n individual who is unable to read because he or she was never taught to read would not be an individual with a disability because lack of education is not an impairment.
Id. But if an individual who previously held a job that did not require much if any reading developed a physical impairment, that individual’s ability to read would have to be taken into account in determining whether he or she was “significantly restricted in the ability to perform either a class of jobs or a broad range of jobs in various classes as compared to the average person having comparable training, skills and abilities.” 29 C.F.R. § 1630.2(j)(3)(i).
For these reasons, we hold that the District Court committed legal error by failing to conduct the necessary individualized assessment of the extent to which Mondzelew-ski’s back condition coupled with his personal characteristics substantially limits his ability to work.
D. The District Court also suggested that the defendants were entitled to summary judgment on Count I because the report of Mondzelewski’s vocational expert failed to “relate the effect of Mondzelewski’s ‘medium duty’ restrictions on his ability to perform jobs in the economy” and failed to “quantify the number or type of jobs he is precluded from performing due to those restrictions.”
Mondzelewski
Yohe’s report recounted Mondzelewski’s educational and vocational background and reported that Mondzelewski had received “extremely low” scores on an achievement test and a career ability placement test that Yohe had administered. App. 162. According to his report, Yohe compared Mondzelew-ski’s profile “to each of the almost 13,000 jobs listed in the [Department of Labor’s] Dictionary of Occupational Titles” and found that “there were a total of eight positions that would be suitable for him that essentially involve unskilled work.” App. 163. Yohe stated that his investigation showed that for these positions there were “very low employment opportunities” in Mondzelewski’s geographical area. Id. He concluded:
In essence, the best that could be hoped for ... him, outside of his Pathmark situation, would be a minimum wage type of position in an unskilled light or medium duty capacity. For him to obtain these types of jobs, he would likely need some sort of assistance from a professional Rehabilitation Specialist.
App. 164. Whatever else may be said of Yohe’s report, we believe that it is sufficient to show for present purposes that Mondze-lеwski is “significantly restricted in the abili *786 ty to perform either a class of jobs or a broad range of jobs in various classes as compared to the average person having comparable training, skills and abilities.” 29 C.F.R. § 1630.2(j)(3)(i).
We reject Pathmark’s argument that Mondzelewski cannot be substantially limited in the major life activity of working because he is now working. In determining whether an individual is substantially limited in a major life activity, a court must examine the individual’s situation without accommodation for the individual’s impairment.
Matczak,
In sum, we hold that the question whether Mondzelewski’s impairment substantially limits him in the major life activity of working cannot be resolved at the summary judgment stage.
III.
A. Mondzelewski next challenges the District Court’s decision to grant summary judgment to Pathmark on his retaliation claim. While recognizing that persons who do not have a disability but “who in good faith file formal disability discrimination charges with [the appropriate state agency] or [the] EEOC” may assert a retaliation claim,
After the District Court’s decision, this Court held that “a person’s status as a ‘qualified individual with a disability’ is not relevant in assessing the person’s claim for retaliation under the ADA.”
Krouse v. American Sterilizer, Co.,
By its own terms, the ADA retaliation provision protects “any individuаl” who has opposed any act or practice made unlawful by the ADA or who has made a charge under the ADA. 42 U.S.C. § 12203(a). This differs from the scope of the ADA disability discrimination provision, 42 U.S.C. § 12112(a), which may be invoked only by a “qualified individual with a disability.” An individual who is adjudged not to be a “qualified individual with a disability” may still pursue a retaliation claim under the ADA.
Id. at 502. Under this analysis, we see no basis for holding that a person who is adjudged not to have a disability may not assert a retaliation claim based on some form of protected activity other than the filing of a formal complaint. Nor do we see any basis for holding that such a person must have suffered some form of retaliation that is more severe than the statute would otherwise demand. Consequently, Krouse necessitates reversal here.
B. Although the District Court did not squarely hold that Mondzelewski’s retaliation claim could not survive summary judgment because the evidence did not show that Mondzelewski had suffered an “adverse employment action,” the Court stated that “it does not believe it would be error” to so hold.
Mondzelewski,
Mondzelewski argues that “[p]erhaps the most egregious actions” taken against him were the “use of ‘punishment shifts.’” Appellant’s Br. at 30. The District Court, however, wrote that, while this was “Mondze-lewski’s most tangible complaint,” “the change in shifts ... must be discounted because of the common sense notion that a 9:00
*787
a.m. to 5:00 p.m. shift cannot be considered an extreme hardship given most of this country’s workers are governed by that shift.”
Mondzelewski,
This provision states in pertinent part:
No person shall discriminate against any individual because such individual has opposed any act or practice made unlawful by this chapter....
42 U.S.C. § 12203(a). As we have noted, see
Krouse,
In Title VII cases, our Court and others have interpreted “discriminatfion]” to mean conduct that falls within the basic prohibition against employment discrimination found in 42 U.S.C. § 2000e-2(a)(l), which makes it an “unlawful employment practice” to discriminate with respect to “compensation, terms, conditions, or privileges of employment.”
See Robinson v. City of Pittsburgh,
We hold that Mondzelewski proffered еvidence sufficient to establish for present purposes that the change in his schedule may have altered the “terms, conditions, or privileges” of his employment in violation of 42 U.S.C. § 12203(a). He proffered evidence that meat workers generally worked shifts that provided them with certain periods of free time and that did not require them to work weekend evenings consistently. His evidence suggested that his fellow employees considered this type of schedule to be a highly desirable benefit. Although Mondzelewski previously had worked under the typical meat worker’s schedule, after his second injury, he was singled out to work a different shift. This shift left him none of the customary free time and required him to work every Saturday evening. Moreover, he proffered affidavits of fellow employees stating that only workers that Pathmark intended to punish were assigned to this undesirable shift. Indeed, according to these affidavits, workers referred to these shifts as “punishment shifts.” We find this evidence sufficient to raise a triable *788 question as to whether Mondzelewski’s terms, conditions, or privileges of employment were altered.
Assigning an employee to an undesirable schedule can be more than a “trivial” or minor change in the employee’s working conditions.
See Hampton v. Borough of Tinton Falls Police Dep’t,
We readily agree with the District Court’s observation that assignment to a 9:00 a.m. to 5:00 p.m. shift “cannot bе considered an extreme hardship given most of this country’s workers are governed by that shift.”
Mondzelewski,
Although the District Court did not expressly address the other alleged acts of retаliation on which Mondzelewski relies, it appears that the Court may have applied the same “extreme hardship” test there as well. Moreover, the Court did not address 42 *789 U.S.C. § 12203(b), which arguably sweeps more broadly than 42 U.S.C. § 12203(a). Subsection (b) provides in pertinent part that it is “unlawful to coerce, intimidate, threaten, or interfere with any individual ... on account of his or her having ... exercise[d] ... any right granted or protected by this chapter.” On remand, the Court should consider whether Mondzelewski has proffered sufficient evidence to survive summary judgment under this subsection as well as under subsection (a).
Pathmark has urged us to affirm the grant of summary judgment on the retaliation claim on several alternative grounds. Path-mark contends thаt Mondzelewski did not make a retaliation charge in his EEOC complaint. Pathmark also argues that it proffered a legitimate explanation for assigning Mondzelewski to the shifts in question — viz., because it was better able to provide reasonable accommodation for his lifting restrictions during those shifts — and that Mondze-lewski failed to raise a triable issue with respect to Pathmark’s explanation. The District Court did not reach these issues, and we decline to reach them at this time. Path-mark can renew these arguments on remand in the District Court.
IV.
For the reasons explained above, we reverse the grant of summary judgment on Counts I and II and remand for further proceedings. We also vacate the dismissal of the counts asserting state-law claims so that the District Court can reassess its decision relating to those counts in light of its disposition on remand of the remaining federal claims.
Notes
. In the District Court, Mondzelewski also argued that he was disabled under 42 U.S.C. §§ 12102(2)(B) and (C) because he has a record of an impairment that constitutes a disability and because Pathmark regarded him as having such an impairment. The District Court rejected these arguments and Mondzelewski has not raised them on appeal.
. Major life activities also include: "caring for oneself, performing manual tasks, walking, seeing, hearing, speaking, breathing, learning....” 29 C.F.R. § 1630.2(i). This list is not meant to be exhaustive, and also includes sitting, standing, lifting, and reaching. 29 C.F.R. Pt. 1630, App. § 1630.2(i). In the District Court, Mondzelewski argued that he is substantially limited in the major life activities of lifting and working. On appeal, Mondzelewski argues only that he is substantially limited in the major life activity of working.
. We have afforded these guidelines "a great deal of deference.”
Matczak v. Frankford Candy & Chocolate Co.,
. Specifically, the Interpretive Guidelines provide:
If an individual is not substantially limited with respect to any other major life activity, the individual's ability to perform the major life activity of working should be considered. If an individual is substantially limited in any other major life activity, no determination should be made as to whether the individual is substantially limited in working. For example, if the individual is blind, i.e., substantially limited in the major life activity of seeing, there is no need to determine whether the individual is also substantially limited in the major life activity of working.
29 C.F.R. Pt. 1630, App. § 1630.2(j).
. Mondzelewski seems to assert that because the alleged harassment caused him to suffer a "nervous breakdown,” the acts are per se retaliatory under the ADA. Mondzelewski erroneously draws support from
