In 2002, the Jefferson County Road Department fired Lynn Zwygart from his position as a truck driver after twelve years of attendance-related problems. He was subsequently reinstated after signing a contract that expressly acknowledged the County’s right to fire him for taking unpaid leave. In 2003, the County exercised its contractual right and fired Mr. Zwygart because he failed to accrue sufficient paid leave, beyond the twelve weeks of leave provided by the Family and Medical Leave Act, to. excuse his absence following an open-heart surgery. Mr. Zwygart sued, alleging that the County’s actions violated his rights under the Americans with Disabilities Act and the Due Process Clause. The district court granted the County’s motion for summary judgment on both claims. We agree that Mr. Zwygart has not demonstrated a triable issue of fact on either claim and therefore affirm the district court’s judgment.
I.
The Jefferson County Road Department hired Mr. Zwygart as a truck driver in 1986. After four years of apparently satisfactory performance, he began displaying attendance problems: in 1990, he used 178 hours of leave without pay; in 1996, he received a written warning for taking 172 hours of leave without pay and 91 hours of sick leave “under questionable circumstances”; and in 1997, he received a second written warning after taking 102 hours of leave without pay. App. 42.
Mr. Zwygart did not alter his behavior in response to the written warnings. In 2000, he was put on probation and later suspended for not providing doctor’s notes to account for his time off. In June 2000, the County told Mr. Zwygart that he had failed to meet conditions imposed in 1997 for his continued employment, including accumulating five days of sick leave and not taking leave without pay. On October 9, 2000, Zwygart secured his supervisor’s written acknowledgment that he had accumulated the required amount of sick leave; within five weeks of doing so, however, he had used it all.
In September 2001, Mr. Zwygart had open heart surgery. He exhausted his annual statutory allotment of Family and Medical Leave Act leave while recuperating before returning to work full time in December 2001.
Mr. Zwygart’s first post-surgery annual performance review occurred in July 2002. It culminated in this July 17, 2002, termination letter from his supervisor:
I have reviewed your work performance evaluations and performance history with Jefferson County Road Department and have found it to be below satisfactory.
As you know from our prior communications, the failure to improve your performance would result in termination from employment. Your performance record this year falls far short of the improvement necessary for you to be retained.
Consequently, this letter is to inform you that your employment with Jefferson County has been terminated as of today.
App. 44.
Mr. Zwygart contested this termination by filing a grievance as outlined in the *1089 County’s employee handbook. The grievance procedure requires department heads to respond to employee grievances “within three ... working days” and “sincere[ly] attempt ... to resolve any grievance at this initial step.” Id. at 64. The mechanism worked; eight days after he filed the grievance, Mr. Zwygart was reinstated after signing — while represented by counsel — a contract with the County that made his continued employment contingent on these conditions: “1. All use of sick leave will require a doctor slip. 2. For no reason will leave without pay be granted. 3. Any violation of these conditions will result in immediate termination.” Id. at 46.
The reinstatement contract, like the written warnings years earlier, did not have much effect on Mr. Zwygart’s actions. In February 2003, Zwygart’s supervisor sent him another letter, which states in part:
Six months ago the County Commission and myself discussed the problem with your work attendance.
At that time your work attendance was unsatisfactory and as a condition of employment you were instructed to do a better job of managing your time off from work. As of today you are out of vacation and sick leave. You’ve also used your discretionary day. The only paid time off you’ve accrued is 2 1/4 hours of comp-time.
It’s clear that you- do not intend to accumulate leave to prevent time off due to unforeseen emergencies or medical needs. This would cause you to take leave without pay, which I will not grant. You have been warned that any use of leave without pay will result in termination.
This letter is to notify you that I am placing you on probation for the next six (6) months. During this time you will be required to accumulate five (5) days of paid leave....
Appellee’s SuppApp. 76.
In May 2003, three months after receiving this letter, Mr. Zwygart was diagnosed with a bacterial infection related to the prosthetic heart valve he had received in his 2001 surgery. On May 19, his doctor provided a “Certification for Work” stating that Mr. Zwygart “has been under my care from 05/12/2003 to present” and “should be off work until further notice.” App. 47. Shortly thereafter Mr. Zwygart began a long-term intravenous antibiotics regimen that continued until September 3, 2003, when he underwent a second open heart surgery to repair a leak around his prosthetic valve. His primary care physician cleared him to return to work on November 28, 2003.
After receiving the May 19 work release from Mr. Zwygart’s doctor, the County granted Zwygart twelve weeks of FMLA leave. When that leave expired, Zwygart used his accumulated sick leave and vacation leave, as well as sick leave other employees had donated to him. Combined, these sources allowed Mr. Zwygart to remain on approved leave through September 15, 2003 — well short of his November 28 return-to-work date.
Beginning September 15, 2003, the County’s records list Mr. Zwygart’s absences as leave “without pay.” App. 56-57. The County classified his absences as such until Mr. Zwygart was fired on October 30, 2003, by this letter from the County engineer:
I regret having to write this letter to you. However, in my capacity with the Jefferson County Road and Bridge Department, I must notify you that you are no longer employed with the County.
As you know, you have long exhausted all sick, vacation and other time, which you have used since the onset of your *1090 medical condition. Additionally, the County has provided you more than the 12 weeks of unpaid medical leave required by the County’s Family and Medical Leave Policy. Everyone was hopeful that your condition would improve and that you could return to your position. Unfortunately, that has not occurred and the County can no longer hold your position for you....
Id. at 52.
As he did two years earlier, Mr. Zwy-gart filed a grievance contesting his termination. This time, however, he received no response from his supervisor, so he forwarded his complaint to the Board of County Commissioners as the grievance policy instructs.
The Board appointed a committee to investigate Mr. Zwygart’s grievance. It held a hearing on December 1, 2003, where Mr. Zwygart testified while represented by counsel that his health was good and that he could return to work as a truck driver. The committee took other evidence, including the November 28 letter from Mr. Zwygart’s primary care physician. After the hearing, Mr. Zwygart submitted a note from his cardiologist dated December 3, 2003, that affirmed Mr. Zwy-gart’s capacity to return to work without restriction.
After reviewing the evidence, the committee issued a report on December 5 recommending that the Commission uphold Mr. Zwygart’s termination for six different reasons. Three days later, the Commission adopted the committee’s recommendation and unanimously sustained Mr. Zwygart’s termination.
Mr. Zwygart then sued the County for wrongful discharge and failure to accommodate in violation of the ADA, and for depriving him of a property interest in his continued employment without due process in violation of the Fourteenth Amendment. The County moved for summary judgment on all of Mr. Zwygart’s claims. The district court granted the County’s motion, holding that Mr. Zwygart was not disabled within the meaning of the ADA and that he failed to establish he had a protected property interest in his employment. Mr. Zwygart timely appealed. We have jurisdiction under 28 U.S.C. § 1291.
II.
A.
We review
de novo
the district court’s grant of summary judgment.
Adair Group, Inc. v. St. Paul Fire & Marine Ins. Co.,
B.
Mr. Zwygart first appeals from the district court’s grant of summary judgment on his ADA claim. A prima facie case of ADA discrimination consists of three elements: the plaintiff (1) is a disabled person as defined by the ADA; (2) is qualified, with or without reasonable accommodation, to perform the essential functions of the job held or desired; and (3) suffered discrimination by an employer or prospective employer because of that disability.
MacKenzie v. City & County of Denver,
Before reaching the merits of the district court’s holding, however, we must address an argument raised by the County on appeal and pressed during oral argument. According to the County, Mr. Zwy-gart’s termination occurred on October 30, 2003, the date he received a letter of termination signed by the County engineer, his supervisor. Because it is undisputed that, as of October 30, Mr. Zwygart’s doctor had not released him to return to work, the County argues that he could not have been a “qualified individual” within the meaning of the ADA: with or without accommodation, he could not perform the essential functions of the job. Appellee's Br. 10; see
Mason v. Avaya Commc’ns,
Taking December 8 as the relevant date of termination, we turn to the district court’s holding that Mr. Zwygart was not disabled under the ADA. Congress defined the term “disability” in the ADA three ways. 42 U.S.C. § 12102(2)(A)-(C). Mr. Zwygart asserts that he is disabled under the second definition&emdash;that he has “a record of’ an impairment that substantially limits a major life activity.
Id.
§ 12102(2)(B). Under our precedent, a plaintiff seeking to prove a disability under § 12102(2)(B) must prove five elements: (1) the plaintiff has a record of, or has been misclassified as having, (2) a recognized impairment that (3) the plaintiff “actually suffered” and that (4) substantially limited (5) a major life activity.
Doebele v. Sprint/United Mgt. Co.,
In this case, we are concerned mainly with the interplay between the fourth and fifth elements of this “record of’ disability test. Mr. Zwygart’s ADA claim centers on the major life activity of working, which is entitled to ADA protection.
See Rakity v. Dillon Cos., Inc.,
These additional factors are relevant to determining whether an impairment substantially limited the major life activity of working because the ADA’s “statutory phrase ‘substantially limits’ requires, at a minimum, that plaintiffs allege they are unable to work in a broad class of jobs.”
Id.
at 491,
[t]o be substantially limited in the major life activity of working, ... one must be precluded from more than one type of job, a specialized job, or a particular job of choice. If jobs utilizing an individual’s skills (but perhaps not his or her unique talents) are available, one is not precluded from a substantial class of jobs. Similarly, if a host of different types of jobs are available, one is not precluded from a broad range of jobs.
Id.
at 492,
Based on this precedent, the district court held that Mr. Zwygart had not created a triable issue of fact as to whether his impairment “substantially limited” his major life activity of working because he “ha[d] not produced any evidence that he was restricted by his doctors from working any job other than as a truck driver for the County from May to December 2003.” App. 104. Mr. Zwygart asserts on appeal, as he did below, that two pieces of evidence make that required showing: his doctor’s May 19, 2003, certification for work stating that “Lynn should be off work until further notice,” id. at 47; and his doctor’s letter dated November 28, 2003, which states in part that Mr. Zwy-gart’s cardiologist “specifically told him that he could not work while on the intravenous antibiotics and in the most recent perioperative period,” id. at 48.
This evidence is insufficient to preclude summary judgment. In at least three cases, we have affirmed a district court’s dismissal of an employee’s ADA claim because the employee failed to provide “a single document or record helpful in addressing his ‘vocational training, the geographical area to which he has access, or the number and type of jobs demanding similar training from which [he] would also be disqualified.’ ”
Rakity,
The November 28, 2003, physician’s note is likewise unavailing. In full, the passage Mr. Zwygart cites states:
“According to Mr. Zwygart,
his cardiologist specifically told him that he could not work while on the intravenous antibiotics and in the most recent perioperative period.” App. 48 (emphasis added). As double hearsay—Mr. Zwygart said that his cardiologist said—-this passage is inadmissible
*1093
under Fed.R.Evid. 802 and therefore “not sufficient to defeat a motion for summary judgment.”
Jaramillo v. Colo. Judicial Dep’t,
Mr. Zwygart’s failure to provide evidence establishing his vocational training, the geographical area to which he had access, and the number and type of jobs demanding similar training from which he would have been disqualified from May to December 2003 dooms his claim. We therefore affirm the district court’s judgment without addressing other factors relevant to the “substantially limited” analysis.
C.
Mr. Zwygart also appeals from the district court’s holding that the County did not deprive him of procedural due process when it fired him. A person alleging that he “has been deprived of his right to procedural due process” must prove two elements: that he possessed a constitutionally protected liberty or property “interest such that the due process protections were applicable,” and that he was not “afforded an appropriate level of process.”
Farthing v. City of Shawnee, Kan.,
Property interests do not stem from the Constitution itself; rather, they “ ‘are created and their dimensions are defined by existing rules or understandings that stem from an independent source such as state law.’ ”
Id.
(quoting
Bd. of Regents of State Colleges v. Roth,
In Kansas, employees are presumptively at-will “in the absence of an express or implied contract.”
Anglemyer v. Hamilton County Hosp.,
On appeal, Mr. Zwygart argues that three factors — the County’s employee handbook, his supervisor’s deposition testimony, and the parties’ “common interpretation ... [of] the County’s leave without pay policy,” Appellant’s Br. 22 — could have led a reasonable jury to find that he had an implied-in-fact contract for continued County employment. This argument, however, misses the point. While these factors may be relevant to deciding whether an implied employment contract exists, they are irrelevant here because Mr. Zwy-gart signed an express contract of employment. On July 30, 2002, he was reinstated only after explicitly agreeing that his continued employment was contingent on *1094 these conditions: “1. Ail use of sick leave will require a doctor slip. 2. For no reason will leave without pay be granted. 3. Any violation of these conditions will result in immediate termination.” App. 46.
It has long been Kansas law that “the existence of an express agreement precludes the idea of the existence of an implied one.”
Ericson v. Charles,
By signing the contract, Mr. Zwygart expressly agreed that his “immediate termination” would result from taking leave without pay. This plain language leads but to one conclusion: Mr. Zwygart did not have a legitimate claim to continued employment if he breached the contract’s conditions. To hold otherwise would be to flout the parties’ clearly expressed intentions in dereliction of our duty to “give effect to” what the parties have “expressed within the four corners of the instrument.”
Blair Constr., Inc. v. McBeth,
When this topic arose during oral argument, Mr. Zwygart’s counsel asserted that the County waived any rights it may have had under the contract by not firing Zwygart on September 16, 2003 — the day he exhausted his approved leave, and thirteen days after his second open-heart surgery. We cannot agree. Under Kansas law, waiver is “the intentional relinquishment of a known right. The intent to waive known rights is essential.”
Prather v. Colo. Oil & Gas Cong.,
That Mr. Zwygart’s termination letter arrived six weeks after he exhausted his leave, instead of two weeks after his open heart surgery, does not change our view. Allowing a grace period is not equivalent to waiver. Employers should not be penalized for failing to spy the clock and axe their employees nanoseconds after they are contractually able to do so. We need not decide in this case what period of elapsed time without a termination is sufficient to show waiver; whatever it may be, we think the County was well within it by *1095 waiting six weeks before firing a man still recuperating after his second open-heart surgery in two years.
CONCLUSION
We AFFIRM the district court’s judgment dismissing Mr. Zwygart’s ADA and due process claims.
