OPINION
Wаyne Hein, a 45-year-old, 5'8", 200-pound truck driver who suffers from hypertension, appeals from an adverse summary judgment ruling in his suit against his former employer, All America Plywood Company (AAP), and its president Kurt Adam Ludwinski. Hein was fired after he refused to make an out-of-town delivery that was assigned to him five days in advance. Contending that he was unable to make the delivery because he would have run out of his blood-pressure medication before his return, Hein alleged that his termination constituted a violation of public policy and illegal disability discrimination. He also claimed discrimination based on both age and weight. The dis- *485 tiict court granted summary judgment in favor of the defendants. For the reasons set forth below, we AFFIRM the judgment of the district court.
I. BACKGROUND
A.Basis for public policy and disability discrimination claims
Hein had worked at AAP for sixteen years. His regular delivery territory was western Michigan and Toledo, Ohio. Since 1989, Hein has been diagnosed with hypertension. His medical routine was to have a periodic check-up every six months with his doctor, at which time the doctor prescribed a six-month supply of blood-pressure medication. Hein’s general practice wаs to call his doctor a week in advance to schedule an appointment. According to this routine, he was due for a check-up on July 8,1997.
Each week, AAP makes at least one delivery to its customers in Cleveland, Ohio. It only had three drivers licensed to make the Cleveland run — Hein, Jack Hinton, and Bill Johnson. Several weeks before the delivery scheduled for July 8, 1997, Hinton, the regular Cleveland driver, posted a notice on the company bulletin board that he would be on vacation. Johnson later notified AAP that he, too, would be unavailable because he needed to stay home to take care of his children on July 8. Hein was consequently given notice by the route scheduler on July 3, 1997 that he was assigned to make the delivery. He told the route sсheduler that he could not make the delivery because he was running out of blood-pressure medicine and needed to see his doctor. Hein admitted, however, that the scheduler did not excuse him from his run.
On the day before the scheduled delivery, Hein told Ludwinski that he would be unable to take the Cleveland assignment because he would run out of his medication during the trip and could not оbtain a timely refill due to his regular doctor being on vacation. He did not attempt to meet with another doctor in the practice group or obtain medication elsewhere prior to this conversation. After the conversation, Ludwinski gave Hein twenty minutes to reconsider. When Hein took no corrective action, Ludwinski told Hein that he should not return to work. Johnson endеd up making the July 8 delivery. Hein’s former route was temporarily taken over by the route scheduler, and then by David Richardson, who was then 29 years old.
B. Basis for age and weight discrimination claims
To prove age and weight discrimination, Hein submitted three pieces of evidence. He first cited a January 1997 “sales update” sheet with a cartoon of a reclining Big Boy from the Big Boy restaurant chain, captioned “Wayne Hein Contemplates Lotto Scheme.” Ludwinski produced these sales updates, which often poked fun at various AAP employees, and distributed them throughout the company.
Next, Hein presented an April 1996 magazine cover that Ludwinski hung in the company’s main office. The cover depicted a gorilla, which Hein described as old, wrinkled, and heavy. The caption on the cover hаd been modified to read “Wayne Hein Ponders Weight Limits.” Although his truck was ticketed for being overweight around the time the cover was produced, Hein argues that this cover was intended to deride his weight.
Finally, Hein noted that his coworkers frequently called him as “Burger Boy,” “Buffet Boy,” “Double Cheese,” and “Turtle Hein,” and highlighted how AAP’s driver-contact list referred to him as “Buffet Boy.” Hein, however, did not establish that any of these nicknames were originated by Ludwinski.
C. Summary of Hein’s legal theories
Hein filed a complaint in the Wayne County Circuit Court alleging disability discrimination under the Americans with Disabilities Act (ADA), 42 U.S.C. *486 §§ 12101-12213, and the Michigan Persons with Disabilities Civil Rights Act (PDCRA), MiCH. Comp. Laws §§ 37.1101-1607; age discrimination under the Age Discrimination in Employment Act (ADEA), 29 U.S.C. §§ 621-634, and the Michigan Elliot-Larsen Civil Rights Act, Mich. Comp. Laws §§ 37.2101-2804; weight discrimination under the Elliot-Larsen Act; and a common law claim of wrongful discharge in violation of public policy. The case was removed to the United States District Court for the Eastern District of Michigan on May 11,1998.
Following discovery, AAP and Ludwin-ski both moved for summary judgment. In an opinion and order dated March 5, 1999, the district court entered summary judgment in their favor. This appeal followed the denial of Hein’s motion for a rehearing.
II. ANALYSIS
A. Standard of review
We review de novo the district court’s grant оf summary judgment.
See, e.g., Holloway v. Brush,
B. Public policy claim
Hein first argues that his termination violated public policy. Under Michigan law, an employee may have a cause of action against his employer when his termination is contrary to clearly articulated public policy.
See Suchodolski v. Michigan Consol. Gas Co.,
An employee has a valid public policy claim under Michigan law if he was fired because his employer requested that he break the law, but he failed or refused to do so.
See Garavaglia v. Centra, Inc.,
Ludwinski, however, never demanded that Hein violate the law by driving without his blood-pressure medication. Instead, Ludwinski told Hein to make his assigned delivery, an assignment made five days in advance of the delivery date. During this time, Hein did not attempt to meet with another doctor or obtain a temporary refill of his blood-pressure medication. Yet Hein, by his own admission, had the responsibility to keep himself medicated. It was thus Hein, rather than his employer, who placed himself in the position of being forced to either violate the federal motor carrier safety laws or abandon his work duties. Accordingly, we find that the public policy exception to the at-will em *487 ployment doctrine is inapplicable under these circumstanсes.
C. Disability discrimination claim
Hein next alleges disability discrimination under the ADA and the PDCRA. The federal ADA and the Michigan PDCRA each require an individual seeking redress to show that he has an impairment that substantially limits a major life activity.
See Gilday v. Mecosta County,
The Supreme Court has expressly held that courts must evaluate a person with high blood pressure in his medicated state in order to determine whether he is disabled under the ADA.
See Murphy v. United Parcel Serv., Inc.,
Hein tries to distinguish his situation from Murphy and Chmielewski by noting that both Murphy and Chmielewski were on medication when fired. In contrast, Hein argues that AAP and Ludwinski prevented him from taking his blood-pressure medication by demanding that he go out on the road at a time when he had no refill. Hein therefore argues that his un-medicated state should be used to evaluate whether he is protected by the ADA and the PDCRA.
Hein’s distinction is unpersuasive. In determining that Murphy should be evaluated in his medicated state, the Supreme Court relied on another case,
Sutton v. United Airlines,
In the present case, Hein successfully performed his duties with the aid of his blood-pressure medication. He admitted that, while on medication, he functions normally and has no problems “whatsoever.” His hypertеnsive condition did not substantially limit him from working. Indeed, this court has held that short-term temporary restrictions on major life activities are generally not disabilities under the ADA.
See Roush v. Weastec, Inc.,
*488 The essence of Hein’s claim is captured in the following argument in his brief: “The bottom line is that at the time he was fired, by no fault of his own, plaintiff did not have his medication.” But it basically was his own fault. Hein concedes in his briеf “that it is his responsibility to obtain his medication,” and that “he made no attempt to obtain an earlier appointment or temporary refill from one of the other two doctors in the office.” Knowing that he must be continuously medicated in order to perform his job as a truck driver, it was his responsibility to not wait until the last minute to obtain refills of his medicine. As pointed out in AAP’s brief, Ludwinski “did not hide Hеin’s medication, or prevent him from getting an appointment or a short supply,” and “did not even know Hein had high blood pressure until July 7, 1997 at approximately 3:00 p.m. when he was required to resolve the issue of who would take the Cleveland run.” Consequently, Hein has failed to establish a valid disability claim.
D. Age and weight discrimination claims
Finally, Hein charges AAP and Ludwinski with age discrimination under the ADEA and with age and weight discrimination under the Elliot-Lаrsen Act. A plaintiff seeking recovery under both acts must bear the burden of proving a prima facie case of discrimination.
See Barnhart v. Pickrel, Schaeffer & Ebeling Co.,
Federal and state courts have recognized that this burden can be met by presenting direct evidence of intentional discriminatiоn, or by providing circumstantial evidence of disparate treatment on a discriminatory basis.
See Mitchell v. Toledo Hosp.,
Hein focuses his argument on what he claims to be “direct evidence” of discrimination. He only tangentially refers to evidence of disparate treatment. Nevertheless, we will address both methods of . proving discrimination.
1. Intentional discrimination
In order for a plaintiff to state a prima facie case of intentional age or weight discrimination, he must present credible, direct evidence of wrongful discrimination.
See Mitchell,
Even if the three pieces of evidence that Hein presented were not deemed to be “isolated,” he still would have failed to establish a prima facie case of intentional age or weight discrimination because the evidence was neither direct nor credible. Hein rеlies solely on the modified magazine cover to establish Ludwinski’s predisposition against older workers, arguing that the gorilla on the cover is old and wrinkled. The gorilla, however, appears age-neutral when viewed objectively, and is therefore at best an ambiguous comment on Hein’s age. Hein’s subjective belief that the gorilla is “old” is insufficient as a matter of law to estаblish intentional age discrimination.
See Mitchell,
Hein also fails to present a prima facie case of intentional weight discrimination. Although the Big Boy sales updates, the references to “weight limits,” and the “Burger Boy” nicknames might raise a genuine issue of material fact as to Ludwinski’s predisposition towards weight discrimination, Hein presented no evidence to connect Ludwinski’s alleged prejudice against heavier individuals with his decision to fire Hein. Both the sales updates and the modified magazine cover were created over five months before Hein was fired, and there is no evidence in the record that Ludwinski initiated the nicknames.
Hein also argues that because his high blood pressure is “inextricably” tied to his weight, Ludwinski’s statement of disbelief about the significance of Hein’s disability constituted evidence that Ludwinski fired Hein on the basis of weight discrimination. Without further support, this is nothing more than a conclusory allegation, and therefore insufficient as a matter of law to establish weight discrimination. See id. Accordingly, the district court correctly found no evidence of intentional discrimination on the basis of age or weight.
2. Disparate treatment
To determine whether a .plaintiff has a valid claim for illegal disparate treatment on the basis of age or weight, we apply the burden-shifting evidentiary framework originally articulated in
McDonnell Douglas Corp. v. Green,
A plaintiff who alleges employment discrimination can show pretext by successfully attacking the proffered reаson for the adverse employment decision.
See Godfredson v. Hess & Clark, Inc.,
Although Hein established a prima facie case of disparate treatment by submitting evidence that a younger driver took over his former route, AAP and Ludwinski shifted the burden of persuasion back to Hein by articulating a clear and legitimate non-discriminatory reason for Hein’s dismissal — his refusal to make the July 8, 1997 delivery. Hein’s subjective interpretation regarding the age of the gorilla portrayed on the April 1996 magazine cover is the only actual evidence he presented to show thаt Ludwinski’s proffered reason was pretextual. As already noted, such subjective interpretations are insufficient as a matter of law to establish a discrimination claim.
See Mitchell,
With respect to Hein’s weight discrimination claim, Hein fails to even state a prima facie case of disparate treatment. No evidence in the record shows that Hein’s replacement weighed less than Hein, or that Hein was treated differently than similarly-situated drivers from outside the protected class. Rather, Hein was the only driver who ever flatly refused to make a requested run under circumstances where it could have been safely done with reasonable diligence on his part. Furthermore, as stated earlier, even assuming that Hein could establish a prima facie case, he failed to rebut the proffered nondiscriminatory explanation that Hein was fired for refusing to make the July 8, 1997 delivery. Hein has therefore failed to establish a valid claim for weight discrimination on the theory of disparate treatment.
III. CONCLUSION
For all the reasons stated above, we AFFIRM the judgment of the district court.
