Applebee’s International, Inc. (Apple-bee’s) brings this interlocutory appeal from the district court’s 1 denial of summary judgment in this employment wage dispute. Gerald A. Fast, Talisha Cheshire, and Brady Gehrling represent a class of 5,543 individuals (collectively “the employees”) who are current and former servers and bartenders at Applebee’s restaurants. They brought suit under the Fair Labor Standards Act (FLSA) based on Apple-bee’s use of the “tip credit” to calculate their wages for purposes of meeting the minimum wage requirements of the FLSA. In denying Applebee’s motion for summary judgment, the district court concluded that the Department of Labor (DOL)’s interpretation of the FLSA as contained in the Wage and Hour Division’s Field Operations Handbook (Handbook) was reasonable, persuasive, and entitled to deference. Applebee’s challenges that conclusion as inconsistent with the relevant statutes and the related regulations. The employees cross-appeal the district court’s allocation of the burden of proof. We affirm the district court’s order.
I.
The fighting issue in this case is how to properly apply the “tip credit” to employees whom both sides agree are “tipped employees” as that term is defined in the FLSA. The FLSA allows employers to pay a minimum cash wage of $2.13 per hour to employees in a “tipped occupation” as long as the employee’s tips make up the difference between the $2.13 hourly cash wage and the current federal minimum wage, presently $7.25 per hour. See 29 *875 U.S.C. § 203(m); 29 U.S.C. § 206(a)(1). The plaintiff servers and bartenders claim that Applebee’s requires them to perform nontip-producing duties for significant portions of their shift while compensating them at the lower $2.13 tipped rate. The plaintiff bartenders claim that they were required to perform such duties as wiping down bottles, cleaning blenders, cutting fruit for garnishes, taking inventory, preparing drink mixers, and cleaning up after closing hours. The servers claim that they performed such duties as cleaning bathrooms, sweeping, cleaning and stocking serving areas, rolling silverware, preparing the restaurant to open, and general cleaning before and after the restaurant was open. Applebee’s counters that servers and bartenders are in tipped occupations, so that any incidental duties they perform as part of that occupation are subject to the tip credit and can be paid at the $2.13 hourly rate, regardless of the amount of time spent performing these duties, as long as each employee’s tips make up the difference between $2.13 per hour and the full minimum wage rate. While the employees dispute its relevancy, both sides agree that the plaintiffs received in employer cash payments and tips a sum at least equal to the required minimum wage per hour for all hours worked.
The DOL regulations recognize that an employee may hold more than one job for the same employer, one which generates tips and one which does not, and that the employee is entitled to the full minimum wage rate while performing the job that does not generate tips.
See
29 C.F.R. § 531.56(e). The DOL’s 1988 Handbook provides that if a tipped employee spends a substantial amount of time (defined as more than 20 percent) performing related but nontipped work, such as general preparation work or cleaning and maintenance, then the employer may not take the tip credit for the amount of time the employee spends performing those duties. (Appellant’s
The parties also disputed the proper burden of proof. The employees argued that they needed to establish only that Applebee’s paid them $2.13 per hour for a period of time and then the burden shifted to Applebee’s to prove that it was allowed to take the tip credit by presenting evidence of the number of hours the employees worked in a tipped occupation. The district court disagreed, concluding that the employees had to do more than show that they were paid $2.13 per hour because the employees did not dispute that they were subject to the tip credit for at least some of their work. The district court concluded that the employees had to “make a prima facie showing which hours were not properly paid” (Dist. Ct. Mar. 4, 2010 Order at 19), and if there were no records of the time spent on specific duties, then the burden would shift to Applebee’s to show that the employees’ calculations were not reasonable.
Applebee’s filed this interlocutory appeal, arguing, as noted above, that the Handbook is contrary to the express language of the statute and regulations. The employees cross-appeal the district court’s allocation of the burden of proof to the employees to prove they were not properly compensated. Both issues are included in the district court’s certification permitting an interlocutory appeal, and we address them in turn.

A. Engaged in a Tipped Occupation
In this interlocutory appeal, we conduct a
de novo
review of the district court’s summary judgment ruling and its statuto
*876
ry interpretation.
See Haug v. Bank of Am., N.A.,
A “tipped employee” as used in § 203(m) is defined as “any employee engaged in an occupation in which he customarily and regularly receives more than $30 a month in tips.” § 203(t). The tip credit does not apply to just any employee who ever received a tip. It applies only to employees engaged in an occupation where the employee “customarily and regularly receives more than $30 a month in tips.” The parties do not dispute that the servers and bartenders involved in this case are engaged in an occupation in which they customarily and regularly receive at least $30 per month in tips and are “tipped employees” under the statute. The dispute revolves around whether the servers and bartenders are “engaged” in those occupations when Applebee’s requires them to perform duties that do not directly result in a tip. Applebee’s argues that the statute is focused on the occupation, not the specific duties performed, such that it can take the tip credit for the entirety of a server’s or bartender’s shift, as long as the employee receives sufficient tips during the shift to make up the difference between $2.13 per hour and $7.25 per hour, regardless of how much time the employee spends performing tip-producing duties. The employees argue that Applebee’s requires them to perform duties outside of the server and bartender occupations for significant parts of their shifts, such that they are entitled to full minimum wage rates when they are not “engaged” in the duties of those occupations.
As noted previously, an employee is a tipped employee if two things occur: 1) he is engaged in an occupation, and 2) the occupation is one in which he regularly and customarily receives at least $30 in tips per month. § 203(t). “Occupation” is not defined in the FLSA. The DOL has promulgated regulations to implement the tip credit.
See
29 C.F.R. §§ 531.50-531.60. Where a statute does not define a term, and “Congress has delegated authority to an agency to implement an ambiguous statute, we are required to accept the agency’s statutory interpretation, so long as it is reasonable.”
Eisenrich v. Minneapolis Retail Meat Cutters & Food Handlers Pension Plan,
The DOL’s regulations recognize that an employee may be engaged in dual jobs. *877 See 29 C.F.R. § 531.56(e) (entitled “dual jobs”); see also 29 C.F.R. § 516.28(a)(4) & (5) (requiring employers to keep records for its tipped employees of “[hjours worked each workday in any occupation in which the employee does not receive tips, and total daily or weekly straight-time payment made by the employer for such hours,” and “[hjours worked each workday in occupations in which the employee receives tips, and total daily or weekly straight-time earnings for such hours”). Section 531.56(e) states that if an employee works two jobs, one in which his work customarily and regularly produces tips and one in which it does not, the employee must be considered to be employed in two occupations, such that the tip credit may not be taken for hours of employment worked in the occupation not subject to tips. See § 531.56(e). The regulation gives the example of a hotel employee who works both as a bartender and as a maintenance man. “He is employed in two occupations, and no tip credit can be taken for his hours of employment in his occupation of maintenance man.” Id. It distinguishes that situation from “a waitress who spends part of her time cleaning and setting tables, toasting bread, making coffee and occasionally washing dishes or glasses,” and “from the counterman who also prepares his own short orders or who, as part of a group of countermen, takes a turn as a short order cook for the group.” Id. “Such related duties in an occupation that is a tipped occupation need not by themselves be directed toward producing tips.” Id.
The parties do not dispute that § 531.56(e) is entitled to
Chevron
deference. They do disagree as to its meaning. While the regulation does provide the example of the waiter/maintenance man and distinguishes those dual jobs from a waitress or counterman performing related duties in their occupations, it does not further explain how to determine if an employee is engaged in dual jobs. The regulation recognizes that an employee may perform “related duties in ... a tipped occupation” that are not themselves tip producing “part of [the] time” and “occasionally,” and that the time spent performing these related duties is subject to the tip credit, but it does not address the impact of an employee performing related duties more than “part of [the] time” or more than “occasionally.” Nor does it define “related duties” or address a tipped employee who performs duties unrelated to his tipped occupation. The regulation’s failure to address these questions makes it ambiguous.
See Barnhart v. Walton,
The DOL has further interpreted its dual jobs regulation through opinion letters, its 1988 Handbook, and in an amicus brief filed in this appeal. In its 1988 Handbook, the DOL recognized and repeated the distinctions made in the regulation between the waiter who also worked as a maintenance man and a waitress who performed some related nontip-producing work. The Handbook states that an employer can take “the tip credit for time spent in duties related to the tipped occupation, even though such duties are not by themselves directed toward producing tips (i.e. maintenance and preparatory or closing activities),” including the examples of a waiter “who spends some time cleaning and setting tables, making coffee, and occasionally washing dishes or glasses.” (Appellants’
These types of agency interpretations (opinion letters and handbooks) of its own regulation are not entitled to
Chevron
deference because they are not subject to notice and comment rule making procedures.
See Gonzales v. Oregon,
The regulation at issue here is of the former type. Congress added the tip provisions to § 203(m) and added the definition of “tipped employee” to § 203(t) in 1966, but it did not define occupation or address the possibility of an employee working more than one occupation for the same employer.
See
Pub.L. 89-601, § 101, 80 Stat. 830, 830 (Sept. 23, 1966). The following year, the Secretary of Labor promulgated the dual jobs regulation in an attempt to further define when an employee is engaged in a tipped occupation, adding subsection (e) to § 531.56.
See
Wage Payments Under the Fair Labor Standards Act of 1938, 32 Fed.Reg. 13,575, 13,580-81 (Sept. 28, 1967). Thus, the dual jobs regulation is not a regulation in which the agency merely parroted the terms of the statute such that the lesser
Skidmore
deference should apply.
See Gonzales,
The Supreme Court has accorded
Auer
deference to agency interpretations of ambiguous regulations with regular frequency in recent years. The Supreme Court relied on
Auer
in deferring to the Federal Reserve System Board’s interpretation of Truth In Lending regulations as revealed
*879
in the Board’s amicus brief filed with the Court where the regulation was silent on the issue at hand, making it ambiguous, and the Board’s stated position was consistent with its past views.
See Chase Bank USA N.A. v. McCoy,
— U.S. -,
We conclude that the DOL’s interpretation of § 531.56(e) is entitled to
Auer
deference. The regulation at issue in
Auer
adopted a salary basis test to interpret 29 U.S.C. § 213(a)(1) for purposes of the FLSA’s overtime pay requirements.
See Auer,
Applebee’s argues that neither the statute nor the regulation places a quantitative limit on the amount of time a tipped employee can spend performing duties related to her tipped occupation (but not themselves tip producing) as long as the total tips received plus the cash wages equal or exceed the minimum wage. The regulation, to which we owe
Chevron
deference, makes a distinction between an employee performing two distinct jobs, one tipped and one not, and an employee performing related duties within an occupation “part of [the] time” and “occasionally.” § 531.56(e). By using the terms “part of [the] time” and “occasionally,” the regulation clearly places a temporal limit on the amount of related duties an employee can perform and still be considered to be engaged in the tip-producing occupation. “Occasionally” is defined as “now and then; here and there; sometimes.”
Webster’s Third New Int’l Unabridged Dictionary
*880
1560 (1986);
see also United States v. Hackman,
A temporal limitation is also consistent with the majority of eases that address duties related to a tipped occupation. The length of time an employee spends performing a particular “occupation” has been considered relevant in many cases. For example, even when the non-tip-producing duties are related to a tipped occupation, if they are performed for an entire shift, the employee is not engaged in a tipped occupation and is not subject to the tip credit for that shift.
See, e.g., Myers v. Copper Cellar Corp.,
Because the regulations do not define “occasionally” or “part of [the] time” for purposes of § 531.56(e), the regulation is ambiguous, and the ambiguity supports the DOL’s attempt to further interpret the regulation.
See Auer,
We note that the parties dispute which specific duties are subject to the 20 percent limit for related duties in a tipped occupation and which duties are the tip-producing part of the server’s or bartender’s tipped occupation itself. The regulation lists activities such as “cleaning and setting tables, toasting bread, making coffee and occasionally washing dishes or glasses” as “related duties in ... a tipped occupation.” § 531.56(e). The Handbook repeats these examples and states that the 20 percent limit applies to “general preparation work or maintenance.” (Appellant’s
