Opinion
KENNARD, J.
Under the Moore-Brown-Roberti Family Rights Act (Gov. Code,1 §§ 12945.1, 12945.2; hereafter CERA) a full-time employee is entitled to a medical leave of absence for a “serious health condition” that makes the employee “unable to perform the functions of the position of that employee.” (§ 12945.2, subd. (c)(3)(C).) In this case, an employee claiming major depression and work-related stress stopped coming to work and requested medical leave. In the employer’s view, the employee did not have a serious health condition and was capable of performing her duties. The employer ordered the employee to return to work, and fired her when she did not. The employee sued.
We address two issues:
First, does an employer’s failure to invoke the CFRA’s dispute-resolution mechanism of having a health care provider jointly chosen by the parties determine the employee’s entitlement to medical leave bar the employer from later claiming that the employee did not suffer from a serious health condition and was capable of performing her job? Our answer is “no.”
Second, if a full-time employee, during the period in which medical leave was sought, continued to perform a similar job for another employer on a part-time basis, does that conclusively establish the ability to do the job for the original employer? We conclude that, although that part-time job is evidence of ability to do similar work for the original employer from whom the employee has sought medical leave, that evidence is not conclusive. Here, because the parties have presented contrary evidence as to whether the employee had a serious health condition that made her unable to do her full-time job, there is a disputed issue of fact that must be resolved at trial.

“Because this case comes before us after the trial court granted a motion for summary judgment, we take the facts from the record that was before the trial court when it ruled on that motion. [Citation.] ‘ “We review the trial court’s decision de novo, considering all the evidence set forth in the moving and opposing papers except that to which objections were made and sustained.” ’ [Citation.] We liberally construe the evidence in support of the party opposing summary judgment and resolve doubts concerning the evidence in favor of that party. [Citation.]” (Yanowitz v. L’Oreal USA, Inc. (2005) 36 Cal.4th 1028, 1037 [32 Cal.Rptr.3d 436, 116 P.3d 1123].)
In 1989, Sutter Health Central (defendant) hired plaintiff Antonina Lonicki to work in the housekeeping department at its hospital in Roseville. In 1993, plaintiff became a certified technician in the hospital’s sterile processing department. Her work performance was good and her attendance was excellent.
In June 1997, the hospital became a level II trauma center. That change, according to plaintiff, led to a major increase in her workload and more stress. The workers in plaintiff’s unit asked for more help, to no avail. In November 1998 the hospital announced that it would lay off three people. In December 1998, plaintiff’s supervisor and the director resigned. They were replaced by Pat Curtis and Steve Jatala, respectively. Actions by Pat Curtis increased plaintiff’s stress. She consulted a doctor.
On July 26, 1999, when plaintiff arrived at work for her 8:00 a.m. shift, supervisor Curtis told her that her new shift would be from noon to 8:30 p.m. Curtis denied plaintiff’s request for a vacation. Plaintiff went home in tears. After talking to her union representative, she telephoned Curtis and said she was too upset to work. That afternoon, Curtis left a message on plaintiff’s telephone answering machine conveying director Steve Jatala’s request that she get medical authorization for her absence.
Plaintiff called her primary care physician, Dr. Roy Harris, but was told that he was on vacation. His office gave her an appointment the next day with a family nurse practitioner, Joe Lobacarro. Plaintiff saw Lobacarro, who gave her a note for a one-month leave of absence for “[mjedical reasons.” He also referred her to a therapist. Later that day, plaintiff brought the note to her employer; she also filled out a form requesting a one-month leave of absence, which she gave to supervisor Curtis.
On August 2, 1999, director Jatala told plaintiff to see Dr. Michael Cohen, an occupational health physician chosen by defendant employer. Plaintiff did [207]*207so on August 4, 1999. After talking to plaintiff for two or three minutes, Dr. Cohen concluded that plaintiff was able to return to work without restrictions, which he stated in a brief written report prepared for defendant. On August 6, director Jatala telephoned plaintiff and told her to return to work on August 9 or face dismissal. Plaintiff talked to a union representative, who suggested that she follow the medical advice given by her primary physician, Dr. Roy Harris. When she discussed the matter with Dr. Harris, he referred her to Psychologist Janice Pettis. Plaintiff saw Pettis on August 11, and thereafter saw her weekly until August 31, 1999.
On August 17, 1999, director Jatala telephoned plaintiff and asked when she would come back to work. Plaintiff replied that on the advice of her doctors, she would return no sooner than August 27. Thereafter Jatala sent a letter to plaintiff stating that he had discussed the matter with plaintiff’s union representative, Mike Egan, and that Jatala would allow plaintiff paid time off—not medical leave—but that plaintiff had to return to work by August 23 or face dismissal.2 On August 24, plaintiff received the letter.
On August 26, plaintiff consulted Dr. Frank Capobianco, a psychiatrist. He wrote her a note stating that she was “disabled by major depression,” that her symptoms were “work related,” that she required “sick leave,” and that her medical leave should be extended to September 26, 1999. The next day, plaintiff delivered the note to director Jatala. He told her to go to the human resources department, which told her that she had been discharged for failure to appear for work on August 23 and August 24, 1999.
After obtaining a right-to-sue letter from the Department of Fair Employment and Housing, plaintiff sued defendant employer for violating the CERA by firing her and by failing to follow CERA procedures when questioning the validity of her sick leave. Defendant moved for summary judgment. As pertinent here, defendant argued that plaintiff was not entitled to medical leave under the CERA because, in the period for which she sought medical leave, she had a part-time job at a different hospital (Kaiser) where her tasks were substantially similar to those she was hired to perform at defendant’s hospital in Roseville. This part-time job with Kaiser, defendant asserted, showed that plaintiff did not have a “serious health condition” that made her “unable to perform the functions” of her full-time job for defendant, as required under the CERA. (§ 12945.2, subd. (c)(3)(C).) Thus, according to defendant, plaintiff did not qualify for CERA medical leave, and hence her discharge by defendant did not violate the CERA.
[208]*208Plaintiff responded that whether she had a serious health condition that left her unable to do her job at defendant’s hospital in Roseville was a disputed issue of fact. She also asserted that because of defendant’s failure to submit that dispute to a health care provider jointly chosen by the parties, a decision that would have been binding (see § 12945.2, subd. (k)), defendant was estopped from arguing that plaintiff did not satisfy the statutory criteria for medical leave.
The trial court rejected plaintiff’s estoppel argument. It agreed with defendant that plaintiff’s part-time job at Kaiser during her leave of absence from defendant’s employment “showed that she could perform the essential functions of her job” for defendant. The court granted defendant’s motion for summary judgment. Plaintiff appealed from the ensuing judgment of dismissal, which the Court of Appeal later affirmed. We granted plaintiff’s petition for review.
II
The CFRA applies to companies with 50 or more employees; it allows an employee up to 12 weeks of unpaid “family care and medical leave” if the employee has worked for the company for more than a year, and has at least 1,250 hours of service during the previous year. (§ 12945.2, subd. (a).) Grounds for the leave are family needs such as the birth or adoption of a child, serious illness of a family member, or, as relevant here, when “an employee’s own serious health condition . . . makes the employee unable to perform the functions of the position of that employee . . . .” (§ 12945.2, subd. (c)(3)(C), italics added.) The CFRA defines a “ ‘[s]erious health condition’ ” as “an illness, injury, impairment, or physical or mental condition that involves either of the following: [][] (A) Inpatient care in a hospital, hospice, or residential health care facility, [f] (B) Continuing treatment or continuing supervision by a health care provider.” (§ 12945.2, subd. (c)(8).)
The employer may require the employee to submit a certification by the employee’s health care provider, which “shall be sufficient if it includes all of the following: [f] (A) The date on which the serious health condition commenced. [1] (B) The probable duration of the condition, [f] (C) A statement that, due to the serious health condition, the employee is unable to perform the function [sic] of his or her position.” (§ 12945.2, subd. (k)(l).)
An employer who “has reason to doubt the validity of’ the employee’s health certification “may require, at the employer’s expense, that the employee obtain the opinion of a second health care provider, designated or approved by the employer, concerning any information certified . . . .” [209]*209(§ 12945.2, subd. (k)(3)(A).) If there is a difference of opinion between the two, “the employer may require, at the employer’s expense, that the employee obtain the opinion of a third health care provider, designated or approved jointly by the employer and the employee . . . .” (§ 12945.2, subd. (k)(3)(C), italics added.) The opinion of the third provider is “binding on the employer and the employee.” (§ 12945.2, subd. (k)(3)(D).)
During the employee’s medical leave, the employer must continue to provide the employee with health benefits (§ 12945.2, subd. (f)), and upon return to work the employee must be given the same seniority as before the leave. (§ 12945.2, subd. (g).)
The CFRA is modeled after federal legislation, the Family and Medical Leave Act of 1993. (29 U.S.C. §§ 2601-2654; hereafter the FMLA.) The language of the CFRA provisions at issue here is virtually identical to the language of their counterparts in the FMLA.
Ill
Plaintiff contends that defendant’s failure to use the CFRA’s dispute-resolution procedure discussed in part II, ante, estops defendant from asserting that when plaintiff sought medical leave, she did not suffer from a serious health condition that made her unable to do her job at defendant employer’s Roseville hospital.
Here, as permitted under the CFRA, defendant employer did require plaintiff to see a second health care provider, chosen by defendant; that provider, unlike plaintiff’s own health care provider, concluded that plaintiff did not have a serious health condition and was able to perform her job for defendant. But defendant never availed itself of the CFRA provision that allows an employer faced with two conflicting medical opinions to refer the matter to a third health care provider, whose opinion is final and binding on both parties. Defendant’s failure to do so, plaintiff contends, bars it from challenging plaintiff’s claim of having a serious health condition that made her unable to do her job at defendant’s Roseville hospital.
To determine the merits of plaintiff’s argument, we need to examine the statutory language. “Our task is to discern the Legislature’s intent. The statutory language itself is the most reliable indicator, so we start with the statute’s words, assigning them their usual and ordinary meanings, and construing them in context. If the words themselves are not ambiguous, we presume the Legislature meant what it said, and the statute’s plain meaning governs. On the other hand, if the language allows more than one reasonable construction, we may look to such aids as the legislative history of the [210]*210measure and maxims of statutory construction. In cases of uncertain meaning, we may also consider the consequences of a particular interpretation, including its impact on public policy.” (Wells v. One2One Learning Foundation (2006) 39 Cal.4th 1164, 1190 [48 Cal.Rptr.3d 108, 141 P.3d 225]; see also Palmer v. GTE California, Inc. (2003) 30 Cal.4th 1265, 1271 [135 Cal.Rptr.2d 654, 70 P.3d 1067].)
Here, the pertinent statutory language does not require an employer faced with two conflicting health care provider opinions to obtain a binding decision from a third health care provider, and it does not say that an employer who fails to obtain such a decision will be barred, in litigation with the employee, from claiming that the employee did not suffer from a serious health condition making the employee unable to work. What the statutory language denotes is a legislative intent to offer the employer a choice of obtaining or not obtaining a binding decision from a third health care provider, if there is a difference of opinion between plaintiff’s health care provider and the one designated by the employer. Subdivision (k)(3)(C) of section 12945.2 simply states that an employer may resort to that remedy. (See § 14 [“ ‘Shall’ is mandatory and ‘may’ is permissive.”].)
Justice Moreno’s concurring and dissenting opinion concludes otherwise. He relies on subdivision (k)(l) of section 12945.2, which, as previously mentioned {ante, at p. 208), provides that a certification by the employee’s health care provider “shall be sufficient if it includes all of the following: [f] (A) The date on which the serious health condition commenced, [f] (B) The probable duration of the condition, [f] (C) A statement that, due to the serious health condition, the employee is unable to perform the function [sz'c] of his or her position.” (Italics added.) By using the italicized three words, the concurring and dissenting opinion concludes, the Legislature intended to provide that an employer’s only way to challenge the validity of a certification is by a two-step process: First, the employer must insist that the employee be examined by the employer’s health care provider; second, if this health care provider concludes that medical leave is not warranted, the employer and the employee must jointly choose a third health care provider to resolve the dispute.
Putting aside for a moment the meaning of the three words on which the concurring and dissenting opinion relies, the location of those words—in subdivision (k)(l) of section 12945.2—is noteworthy. This subdivision of the CFRA has nothing to do with the third health care provider; rather, it discusses the employer’s right to insist on a certification showing that the employee suffers from a condition that necessitates medical leave. It would be odd, to say the least, for the Legislature to have placed language requiring employers to use a third health care provider in such a provision. This is [211]*211particularly true because of the far-reaching consequences of the concurring and dissenting opinion’s interpretation of those words: Employers would be completely barred, in all cases, from litigating an employee’s entitlement to medical leave. (An employer who uses the third health care provider is, under the statutory scheme, expressly barred from challenging the health care provider’s determination, which is binding (§ 12945.2, subd. (k)(3)(C)); and under Justice Moreno’s construction, subdivision (k)(l) of section 12945.2 equally bars an employer who does not use the third health care provider.)
Had the Legislature intended to take such a dramatic step, surely it would have expressed that intent in a subdivision pertaining to the third health care provider, rather than a subdivision dealing solely with employee certifications. And instead of the three ambiguous words “shall be sufficient,” surely the Legislature would have used clear and unambiguous language similar to that used in subdivision (k)(3)(D) of section 12945.2, where it said the decision of the third health care provider “shall be considered to be final and shall be binding on the employer . . . .”
In any event, as explained below, subdivision (k)(l) of section 12945.2 does not require an employer to submit disputes regarding an employee’s entitlement to medical leave to a third health care provider.
By stating that an employee’s certification “shall be sufficient” if it contains the commencement date that the employee’s health condition began, the “probable duration of the condition,” and a statement that the condition renders the employee unable to do the job, subdivision (k)(l) of section 12945.2 limits the type of information that an employer can require an employee to provide in a certification. For example, an employer may not require an employee seeking medical leave to provide detailed intimate and private information about a serious psychiatric condition that has made the employee unable to do the work, nor may the employer deny the employee’s request for medical leave for failing to provide such information. This statutory provision also limits an employer’s right, in litigation arising out of an employee’s medical leave request, to claim that the employer acted reasonably because the information provided by the employee was inadequate: If an employer fires an employee who has given the employer a facially valid certification in support of a request for medical leave and the employee then sues for violation of the CERA, the employer may not defend the suit by asserting that the employee, when requesting leave, provided insufficient evidence that the employee fell within the provisions of the CERA. But subdivision (k)(l) of section 12945.2 does not limit the employer’s choice of legal remedies. It does not say that when an employer questions the validity of an employee’s medical leave request that is supported by a valid certification, the employer’s only recourse is to submit the [212]*212matter to a third health care provider for a binding determination. And it does not say that when an employee who has been denied medical leave sues the employer for violation of the employee’s rights under the CFRA, the employer’s failure to have the dispute submitted to a third health care provider estops the employer from denying in the litigation that the employee suffered from a serious health condition.
Our conclusion finds support in Rhoads v. F.D.I.C. (4th Cir. 2001) 257 F.3d 373, a federal appellate decision. There, the court construed the dispute-resolution provisions of the FMLA, which, as we noted earlier, are identical to those in the CFRA. The court stated: “The FMLA provides only that an employer ‘may’ seek a second, or third, opinion if it questions the validity of an employee’s proffered medical certification of her condition. [Citations.] Because the term ‘may’ is permissive, the plain language of the statute indicates that an employer who questions the validity of a certification has the option of seeking a second and third opinion, without being required to do so. Moreover, the plain language of the [FMLA] does not suggest that an employer must pursue these procedures or be forever foreclosed from challenging whether an employee suffered from a serious health condition; and nothing in the legislative history of the FMLA explicitly supports that interpretation.” (Rhoads v. F.D.I.C., supra, 257 F.3d at pp. 385-386.) Two other federal circuit courts have reached the same conclusion. (Novak v. Metrohealth Medical Center (6th Cir. 2007) 503 F.3d 572, 579; Stekloff v. St. John’s Mercy Health Systems (8th Cir. 2000) 218 F.3d 858, 860 (Stekloff).)
To the contrary are three federal trial court decisions and an appellate court decision from the State of Louisiana, which plaintiff has cited and which we discuss below.
In Sims v. Alameda-Contra Costa Transit Dist. (N.D.Cal. 1998) 2 F.Supp.2d 1253 (Sims), the employer took disciplinary action against a bus driver after he failed to come to work for two weeks, concluding that the absence was unexcused. The employer never asked the driver, who said he had a back problem and furnished corroborating notes from two physicians and a chiropractor, to submit to an examination by the employer’s health care provider. After the employer discharged the driver in the wake of another unexcused absence occurring two months thereafter, the driver sued under both the FMLA and the CFRA, claiming that his back problem was a serious health condition and that his two-week absence was therefore statutorily authorized medical leave.
The federal trial court in Sims concluded that because the employer had not used the dispute-resolution procedures of the FMLA and CFRA, it was barred from challenging the accuracy of the physician notes that the driver had [213]*213submitted to his employer upon returning to work from his two-week absence. The court reasoned: “To allow courts, rather than doctors, to determine the medical condition of an employee who seeks leave would upset the balance between the eligible employee’s right to swift and expeditious coverage and the employer’s right to ensure that the requested leave is needed. The policy of providing swift and expeditious coverage would be undermined if an employer could simply deny leave to an employee who has presented adequate certification of his need for and entitlement to medical leave. An employee in that situation would have no recourse other than to forego the leave to which he may be entitled under the [FMLA] ... or to take leave, suffer the employer’s discipline . . . , sue his employer, and then wait for the court to decide. Time is of the essence when an employee requests medical leave.” (Sims, supra, 2 F.Supp.2d at p. 1261.) Relying on Sims, two other federal trial courts and a Louisiana appellate court have reached similar conclusions. (Wheeler v. Pioneer Developmental Services, Inc. (D.Mass. 2004) 349 F.Supp.2d 158, 167; Washington v. Fort James Operating Co. (D.Or. 2000) 110 F.Supp.2d 1325, 1333-1334; Williams v. Rubicon, Inc. (La.Ct.App. 1999) 754 So.2d 1081, 1085-1086.) We are not persuaded.
Under both the CFRA and its federal counterpart, the FMLA, an employee is entitled to medical leave when, because of a serious health condition, the employee cannot perform the assigned job’s duties. If an employer doubts the validity of such a claim, nothing in either law precludes the employer from denying the employee’s request for medical leave and discharging the employee if the employee does not come to work. Of course, an employer embarking on that course risks a lawsuit by the employee and perhaps a finding by the trier of fact that the employer’s conduct violated the employee’s rights under either the CFRA or the FMLA, or both, by denying the requested medical leave. To avoid such risks, the employer can resort to the dispute-resolution mechanism provided for by both laws.
To summarize: Defendant employer’s failure to use the CFRA’s dispute-resolution procedure—obtaining a binding determination by a third health care provider when there are two conflicting opinions—does not bar it from asserting, in this litigation, that it was justified in firing plaintiff because she did not meet the statutory requirement of having a serious health condition that made her unable to do her job.
IV
As discussed earlier, the CFRA entitles a full-time employee to take medical leave of up to 12 weeks' when the employee has a “serious health condition that makes the employee unable to perform the functions of the position of that employee.” (§ 12945.2, subd. (c)(3)(C).) Here, it is undisputed that, during the time plaintiff claims she had a serious health condition [214]*214that made her unable to do her full-time job as a technician in the sterile processing department at defendant’s Roseville hospital, she had a part-time job with nearly identical duties at a different hospital, Kaiser. In her deposition, plaintiff admitted that her duties at Kaiser were “[ajbout [the] same,” but that it was “a lot slower” at Kaiser because, unlike defendant’s hospital, Kaiser was not a trauma hospital and did not get “bad cases.”
In granting defendant’s motion for summary judgment, the trial court ruled that plaintiff’s ability to work part-time for Kaiser in a job that was similar to the one she had at defendant’s hospital, at a time when she claimed that because of a serious medical condition she could not do her job for defendant, conclusively demonstrated that she was able to perform her duties at defendant’s hospital. The Court of Appeal affirmed the trial court, reasoning that under the CFRA an employer must grant medical leave only if the employee is unable to perform the employee’s essential job functions “generally, rather than for a specific employer.”
Plaintiff challenges the Court of Appeal’s holding, arguing that the relevant inquiry is whether a serious health condition made her unable to do her job at defendant’s hospital, not her ability to do her essential job functions “generally,” as the Court of Appeal concluded. She is right. Neither the CFRA nor the FMLA, after which the CFRA was modeled, has language supporting the Court of Appeal’s holding.
Pertinent here is this statement from a leading treatise on employment litigation: “A showing that an employee is unable to work in the employee’s current job due to a serious health condition is enough to demonstrate incapacity. The fact that an employee is working for a second employer does not mean he or she is not incapacitated from working in his or her current job.” (Chin et al., Cal. Practice Guide: Employment Litigation (The Rutter Group 2006) f 12:266, p. 12-28 (rev. # 1, 2006).) Some six years earlier, in Stekloff, supra, 218 F.3d 858, a federal appellate court made the same point.
The plaintiff in Stekloff worked as a psychiatric nurse. After an argument with her supervisor, she left work, and thereafter obtained a note from her physician recommending that she not return to work for two weeks. When the employer fired her for “job abandonment,” she sued, claiming violation of the FMLA. The federal trial court ruled that the employer was entitled to summary judgment because, at the time of discharge, the plaintiff was working part time as a nurse for a different employer. The federal court of appeals disagreed. It held: “[A] demonstration that an employee is unable to work in his or her current job due to a serious health condition is enough to show that the employee is incapacitated, even if that job is the only one that the employee is unable to perform.” (Stekloff, supra, 218 F.3d at p. 861.) The [215]*215court explained that “the inquiry into whether an employee is able to perform the essential functions of her job should focus on her ability to perform those functions in her current environment.” (Id. at p. 862.) We agree.
Stekloff involved the FMLA, whereas here it is the CFRA that is at issue. But, as we observed earlier, the CFRA is modeled after the FMLA, and the language of the CFRA provision at issue here is virtually identical to the language of its counterpart in the FMLA.3 Therefore, we see no reason not to apply the statutory analysis of Stekloff, supra, 218 F.3d 858, here.
When a serious health condition prevents an employee from doing the tasks of an assigned position, this does not necessarily indicate that the employee is incapable of doing a similar job for another employer. By way of illustration: A job in the emergency room of a hospital that commonly treats a high volume of life-threatening injuries may be far more stressful than similar work in the emergency room of a hospital that sees relatively few such injuries. Also, the circumstance that one job is full time whereas the other is part time may be significant: Some physical or mental illnesses may prevent an employee from having a full-time job, yet not render the employee incapable of working only part time.
The Court of Appeal here expressed concerns about abuse of the CFRA’s medical leave provisions by employees who, like plaintiff here, assert stress-related claims: “[Ejveryone would like to hold a job as stress free as possible. [Citation.] But stress inheres in most jobs, and personality conflicts with coworkers, particularly supervisors, can arise. If an employee is entitled to make legal demands on an employer merely because his or her boss creates stress, . . . ‘supervisors would no longer be able to manage effectively, without fear of constant demands for transfer by their increasingly hypersensitive employees.’ ”
Those concerns raise issues of policy that should be addressed to the Legislature rather than this court, whose task is limited to construing the laws enacted by the Legislature. Both the CFRA and its federal counterpart, the FMLA, allow medical leave for a stress-related condition, as long as the condition is so serious as to prevent the employee from doing the assigned job. Indeed, a federal regulation interpreting the FMLA expressly states that [216]*216“[m]ental illness resulting from stress . . . may be [a] serious health condition[] . . . .” (29 C.F.R. § 825.114(c) (2007).) The California Fair Employment and Housing Commission, the agency responsible for administering the CFRA, has incorporated by reference the federal regulations interpreting the FMLA to the extent they do not conflict with the CFRA, the California Constitution, and other state laws. (Cal. Code Regs., tit. 2, §7297.10.)
Defendant employer here considers it significant that one of those federal regulations (29 C.F.R. § 825.115 (2007)) defines an employee’s inability to perform essential functions of the assigned job by reference to the Americans with Disabilities Act of 1990. (42 U.S.C. § 12101 et seq.; hereafter ADA.) According to defendant, “courts applying the ADA have not found a qualifying disability, where the employee’s claim is limited to a specific shift or supervisor.” At issue here is not plaintiff’s ability to work a particular shift, but whether her part-time work for a different employer conclusively established her ability to work full time for defendant. Also, the ADA is a distinct statutory scheme, whose provisions do not resemble those in either the FMLA or its California counterpart, the CFRA. That distinction is expressly recognized in the federal regulations interpreting the FMLA: “ADA’s ‘disability’ and FMLA’s ‘serious health condition’ are different concepts, and must be analyzed separately.” (29 C.F.R. § 825.702(b) (2007).)
We therefore conclude that under section 12945.2’s subdivision (c)(3)(C), which entitles an employee to medical leave when suffering from a “serious health condition” that “makes the employee unable to perform the functions of the position of that employee” (italics added), the italicized phrase refers to the job assigned to the employee by his or her employer, it does not refer, as the Court of Appeal here held, to “an inability to perform the essential job functions generally, rather than for a specific employer.”
In this case, plaintiff’s ability, during the period when she was seeking medical leave from defendant employer, to work part time for a different hospital (Kaiser), doing tasks virtually identical to those she claimed she was unable to perform for defendant, is strong evidence that she was capable of doing her full-time job at defendant’s Roseville hospital. But that evidence is not dispositive, as it is contradicted by plaintiff and her treating psychologist. Thus, whether plaintiff did have a serious health condition that made her unable to do her full-time job for defendant is a disputed issue of fact to be resolved at trial. Consequently, the trial court erred in granting defendant’s summary judgment motion on the ground that plaintiff’s ability to work part [217]*217time at Kaiser conclusively established her ability to perform similar duties full time at defendant’s hospital.4
Disposition
The judgment of the Court of Appeal is reversed, and the matter is remanded to that court for further proceedings consistent with this opinion.
George, C. J., and Werdegar, J., concurred.
