Thurston County (County) pays its
Fairhurst, J.
employees for nonregular wages (e.g., overtime wages) at the close of the month subsequent to when the nonregular wages were earned. Petitioners Gene Champagne, Cary Brown, Roland Knorr, and Christopher Scanlon (hereinafter collectively referred to as Champagne) work as corrections officers for the Thurston County Sheriff’s Office. Champagne challenges a published Court of Appeals decision that dismissed his claims under the Washington Minimum Wage Act (MWA), chapter 49.46 RCW, wage payment act (WPA), chapter 49.48 RCW, and wage rebate act (WRA), chapter 49.52 RCW, since all wages owed Champagne were eventually paid. He argues that (1) delayed payment of wages beyond the time frame set forth in former WAC 296-128-035 (1989) gives rise to employer liability under the aforementioned statutes and (2) such claims, being statutorily based, are not subject to the claim filing statutes applicable to counties.
¶2 We affirm the Court of Appeals but for different reasoning. We hold (1) that delayed payment of wages [73]*73beyond the time frame set forth in former WAC 296-128-035 gives rise to employer liability under the WRA but only where such delay is willful, and here it was not willful; (2) that delayed payment of wages does not give rise to employer liability under the MWA; and (3) that the WPA does not apply outside the termination context. Since Champagne lacks a viable cause of action, we decline to reach the issue of whether claims made under the WRA, MWA, or WPA are subject to county claim filing statutes.
I. FACTUAL AND PROCEDURAL HISTORY
¶3 The administration of the county payroll system triggered the present controversy. The County pays its employees once a month on the last business day of each month for the regular wages earned that month. Employees who have earned additional compensation such as overtime pay, compensatory time, specialty pay, supervisor pay, or holiday pay (hereinafter collectively referred to as additional pay)1 must submit a form to the County by the end of [74]*74the month for processing. The County pays additional pay at the end of the month subsequent to the month in which it is earned. 2 This practice is memorialized in the governing collective bargaining agreement between the County and its employees with respect to compensatory time and wages for overtime.3 Champagne is employed by the Thurston County Sheriff’s Office as a corrections officer and is eligible for additional pay. Champagne asserts that the County’s practice of paying additional pay the month after it is earned violates Washington’s wage statutes.
¶4 On September 17,2004, Champagne filed suit against the County in Thurston County Superior Court, seeking class certification and claiming that the separate payday for additional pay violates the MWA, WPA, and WRA. In his complaint, Champagne prayed for the following relief: (1) twice the amount of additional pay pursuant to the WRA, (2) class certification, (3) attorney fees and costs under all three wage statutes, (4) prejudgment interest, and (5) any other equitable relief as the court deems just. Prior to filing suit, Champagne did not file a claim for damages with the County.
¶5 The County moved for summary judgment, arguing that Champagne failed to meet the “condition precedent” of filing the claim with the County pursuant to RCW 36-.45.010 and chapter 4.96 RCW (hereinafter collectively referred to as nonclaim statutes). Clerk’s Papers (CP) at 42. Champagne countered that the nonclaim statutes do not [75]*75apply to wage-and-hour claims. Visiting Judge Hogan4 held that Champagne’s claims were subject to the nonclaim statutes, granted the County’s motion for summary judgment, and dismissed the claim without prejudice. Champagne responded by filing a notice of appeal, submitting a claim for damages with the County, and filing a new lawsuit against the County.5
¶6 The Court of Appeals, Division Two, affirmed on alternative grounds and did not reach the issue of whether wage-and-hour claims are subject to the conditions set forth in the nonclaim statutes. Champagne v. Thurston County, 134 Wn. App. 515, 520 n.7, 141 P.3d 72 (2006). Instead, Judge Hunt, writing for a unanimous panel, found that this court’s holding in Seattle Professional Engineering Employees Ass’n v. Boeing Co., 139 Wn.2d 824, 991 P.2d 1126, 1 P.3d 578 (2000) (SPEEA) precluded a cause of action for delayed payment of wages.
Correction Officers alleged in their complaint only that they were entitled to double damages under RCW 49.52.070. In so doing, they failed to state an actionable claim because, under Washington’s wage-and-hour laws, employees are entitled to damages only where an employer has paid no compensation to an employee. Such is not the case here, however, because, as Correction Officers acknowledge, the County did pay them their due wages.

[76]*76II. ISSUE
¶8 Does the WRA, MWA, or WPA provide a cause of action for delayed payment of wages?
III. ANALYSIS
¶9 This court reviews questions of law de novo. Wingert v. Yellow Freight Sys., Inc., 146 Wn.2d 841, 847, 50 P.3d 256 (2002). “In reviewing an order granting summary judgment, the appellate court engages in the same inquiry as the trial court.” Id. Summary judgment is appropriate when “there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law.” Id.; CR 56(c). The court will consider the evidence in the light most favorable to the nonmoving party, drawing all reasonable inferences therefrom. Wingert, 146 Wn.2d at 847.
¶10 This court has described Washington as a “ ‘pioneer’ ” in assuring payment of wages due an employee. Int’l Ass’n of Fire Fighters, Local 46 v. City of Everett, 146 Wn.2d 29, 35, 42 P.3d 1265 (2002) (quoting Drinkwitz v. Alliant Techsystems, Inc., 140 Wn.2d 291, 300, 996 P.2d 582 (2000)). Toward that end, three wage statutes penalize an employer who willfully withholds wages (WRA), fails to pay the statutory minimum wage (MWA), or fails to pay wages due upon termination of employment (WPA). The court is tasked with construing these laws “ ‘liberally’ ” in light of the strong public policy to protect workers’ rights. Id. (quoting Ellerman v. Centerpoint Prepress, Inc., 143 Wn.2d 514, 520, 22 P.3d 795 (2001)).
[77]*77A. Does the amended version of WAC 296-128-035 apply retroactively?
¶11 Pursuant to the MWA, WAC 296-128-035 designates the time by which an employer must pay all wages due.6 Champagne relies upon the rule as it existed at the time he filed his suit in September 2004. In its entirety, former WAC 296-128-035 provided:
All wages due shall be paid at no longer than monthly intervals to each employee on established regular pay days. To facilitate bookkeeping, an employer may implement a regular payroll system in which wages from up to seven days before pay day may be withheld from the pay period covered and included in the next pay period.
Champagne maintains that the County violated former WAC 296-128-035 since the County paid additional pay the month after it was earned. The County, however, urges the court to apply the amended WAC retroactively.
¶12 Current WAC 296-128-035 is similar to its former version but includes additional direction. The current WAC provision states, “[a]n employer shall pay all wages owed to [78]*78an employee on an established regular pay day at no longer than monthly payment intervals.” WAC 296-128-035(3). The additional direction provides:
An employer shall pay overtime wages owed to an employee on the regular pay day for the pay period in which the overtime wages were earned. If the correct amount of overtime wages cannot be determined until after such regular pay day, the employer may establish a separate pay day for overtime wages; provided, that the payment of overtime wages may not be delayed for a period longer than that which is reasonably necessary for the employer to compute and arrange for payment of the amount due, and overtime wages must be paid by the regular pay day following the next pay period.
WAC 296-128-035(6). Furthermore, the rule may be “superseded by a collective bargaining agreement” subject to certain conditions.7 WAC 296-128-035(8).
¶13 Champagne concedes that he lacks a cause of action under current WAC 296-128-035 given that sections six and eight would permit the month delay for additional pay. Therefore, the court must determine whether the former or current WAC provisions apply. In other words, is the amended language retroactive?
[79]*79¶14 Generally, we presume prospective application of newly amended administrative regulations, particularly where the amendments change substantive rights. In re Pers. Restraint of Shepard, 127 Wn.2d 185, 193, 898 P.2d 828 (1995). However, courts may apply an amendment retroactively if either (1) the agency intended the amendment to apply retroactively, (2) the effect of the amendment is remedial or curative, or (3) the amendment serves to clarify the purpose of the existing rule. Magula v. Benton Franklin Title Co., 131 Wn.2d 171, 181-82, 930 P.2d 307 (1997); see also Letourneau v. Dep’t of Licensing, 131 Wn. App. 657, 665-66, 128 P.3d 647 (2006) (applying the above guidelines to determine whether a WAC rule should apply retroactively).
¶15 Both parties acknowledge that “[a] regulation may be given retroactive effect where its purpose is to clarify rather than change the law.” Reply in Supp. of Pet. for Review at 11; Suppl. Br. of Resp’t at 4 n.2 (citing Magula, 131 Wn.2d at 182). However, Champagne urges the court to apply the amendments prospectively, arguing only that the amendments affect a “substantive or vested right.” Reply in Supp. of Pet. for Review at 11 (citing Letourneau, 131 Wn. App. at 665).
¶16 Thus, the issue is whether the rule revision affects a substantive or vested right. The proposed rule statement put forth by the Department of Labor and Industries suggests that the changes were intended to “clarify rule language without changing its effect” pursuant to RCW 34.05.310(4)(d). Wash. St. Reg. 06-17-136 (Sept. 6, 2006). At first blush, this would seem to fit "under the exception carved out in Maguía. However, the actual effects of the amendments go beyond mere clarification. Current WAC 296-128--035(6) permits the payment of additional pay in intervals longer than one month. This practice would have violated the plain language of the previous rule and, thus, denotes [80]*80a change in substantive rights.8 Further, the effect of the amendment is not remedial, which similarly militates against retroactive application. Accordingly, we hold that amended WAC 296-128-035 applies prospectively only, and we will apply former WAC 296-128-035 as it existed when the complaint was filed in 2004.
B. Does the WRA provide a remedy for wages untimely paid in violation of former WAC 296-128-035?
¶17 Champagne claims that the County’s practice of paying additional pay at the end of the month subsequent to when it was earned violates the WRA. The WRA states, “[a]ny employer . . . who . . . [w]ilfully and with intent to deprive the employee of any part of his wages, shall pay any employee a lower wage than the wage such employer is obligated to pay such employee by any statute, ordinance, or contract . . . [s]hall be guilty of a misdemeanor.” RCW 49.52.050(2). A WAC provision may also provide the basis for a WRA action since agency regulations carry the force of law. White v. Salvation Army, 118 Wn. App. 272, 287-88, 75 P.3d 990 (2003) (citing Wingert, 146 Wn.2d at 848).9 Pursuant to the WRA, an employer’s violation of an agency rule [81]*81must be willful and with the intent to deprive its employee of wages.
¶18 A willful withholding under RCW 49.52.050(2) is a basis for exemplary damages in a civil action of “twice the amount of the wages unlawfully rebated or withheld . . . together with costs of suit and a reasonable sum for attorney’s fees.” RCW 49.52.070.10 This court defines a willful withholding as “ ‘the result of knowing and intentional action and not the result of a bona fide dispute as to the obligation of payment.’ ” Wingert, 146 Wn.2d at 849 (quoting Chelan County Deputy Sheriffs’ Ass’n v. County of Chelan, 109 Wn.2d 282, 300, 745 P.2d 1 (1987)). Abona fide dispute is a “ ‘fairly debatable’ dispute over whether an employment relationship exists, or whether all or a portion of the wages must be paid.” Schilling v. Radio Holdings, Inc., 136 Wn.2d 152, 161-62, 961 P.2d 371 (1998) (citing Cannon v. City of Moses Lake, 35 Wn. App. 120, 125, 663 P.2d 865 (1983); Moran v. Stowell, 45 Wn. App. 70, 81, 724 P.2d 396 (1986); Chelan County Deputy Sheriffs’ Ass’n, 109 Wn.2d at 301).
¶19 Determining willfulness is a question of fact reviewed under the substantial evidence standard. Pope v. Univ. of Wash., 121 Wn.2d 479, 490, 852 P.2d 1055, 871 P.2d 590 (1993) (citing Lillig v. Becton-Dickinson, 105 Wn.2d 653, 660, 717 P.2d 1371 (1989)). However, where no dispute exists as to the material facts, the court may dispose of such [82]*82questions on review of summary judgment. Schilling, 136 Wn.2d at 160; CR 56(c).11
¶20 In the present case, neither party disputes the material facts. The County’s regular practice is to pay its employees additional pay at the end of the month subsequent to the month in which it is earned. The lag time violated former WAC 296-128-035, which required an employer to pay its employee at no longer than monthly intervals. However, this system complies with the provisions in the governing collective bargaining agreement with respect to overtime wages and compensatory time. Further, Champagne does not allege that bad faith or animus motivated the creation or administration of the additional pay system. Accordingly, the record lacks the requisite substantial evidence that gives rise to a finding of willful withholding on the part of the County. This is more likely a bona fide dispute over whether the wages were due by a certain time.
f21 We now turn to the disposition of the claim by the Court of Appeals and the County’s argument. The Court of Appeals held, and the County argues, that Champagne may not assert claims under the WRA since the wages due were eventually paid. The Court of Appeals determined that Champagne lacked a viable action under the WRA based upon this court’s language in SPEEA. In SPEEA, we described the differing functions of the WRA, MWA, and WPA. We then proceeded to discuss the implications of the MWA. “The import of this statutory scheme is that in circumstances where an employer paid no compensation [83]*83whatsoever to an employee, the employee, if not otherwise exempt under the [MWA], could recover wages representing the difference between the statutory minimum wage and what was actually paid.” SPEEA, 139 Wn.2d at 831 (citing RCW 49.46.090(1)). The Court of Appeals seized upon this language in dismissing Champagne’s wage claim.
¶22 The Court of Appeals erred in two respects. First, it took the language from SPEEA out of context. The SPEEA court recognized that a plaintiff could recover WRA damages in addition to the unpaid wages recoverable under the MWA.12 139 Wn.2d at 831. However, the court addressed only the extent of recovery available under the MWA, not the WRA, because the plaintiffs had not pursued remedies under the WRA. Id. Conversely, since Champagne has pursued remedies under the WRA, the Court of Appeals should have limited its application of SPEEA to Champagne’s MWA claim and not his WRA claim.
¶23 Second, the Court of Appeals erred by concluding that a violation of former WAC 296-128-035 triggers the remedies available in the MWA (ch. 49.46 RCW) but not the WRA (ch. 49.52 RCW) or WPA (ch. 49.48 RCW). Champagne, 134 Wn. App. at 520 n.5 (former WAC 296-128-035 “applies only to violations of minimum wage laws under chapter 49.46 RCW, not chapters 49.48 and 49.52 RCW”). This conclusion is inconsistent with the plain language of the WRA, which penalizes an employer who willfully withholds wages due under “any statute, ordinance, or contract,” RCW 49.52.050(2), including substantive agency regulations. White, 118 Wn. App. at 287-88. Accordingly, the Court of Appeals misapplied the reasoning in SPEEA to dismiss Champagne’s WRA claim.
[84]*84¶24 Therefore, we affirm the Court of Appeals on different grounds.13 We hold that former WAC 296-128-035 provides a basis for liability if the undisputed material facts support a finding that the violation was willful. Here, we find that the County did not act willfully since the disagreement over payment of wages is a bona fide dispute.
C. Does Champagne’s prayer for relief limit review to the WRA?
¶25 Washington follows notice pleading rules and simply requires a “concise statement of the claim and the relief sought.” Pac. Nw. Shooting Park Ass’n v. City of Sequim, 158 Wn.2d 342, 352, 144 P.3d 276 (2006); CR 8(a). A complaint fails to meet this standard if it neglects to give the opposing party “fair notice.” Pac. Nw. Shooting Park, 158 Wn.2d at 352 (citing Dewey v. Tacoma Sch. Dist. No. 10, 95 Wn. App. 18, 26, 974 P.2d 847 (1999) (finding that a party may not later insert an argument into its briefs that was not first pleaded)).
¶26 The Court of Appeals excluded Champagne’s claims under the MWA (ch. 49.46 RCW) and WPA (ch. 49.48 RCW) for failure to properly plead them in the complaint. “Although Correction Officers also alleged violations of chapters 49.46 and 49.48 RCW, they failed to request any form of relief under these other wage statutes that differs substantively from chapter 49.52 RCW relief.” Champagne, 134 Wn. App. at 520 n.5 (citing SPEEA, 139 Wn.2d at 831, 835). Again, SPEEA is factually distinct from the present case. In SPEEA, the court concluded that appellants had limited the scope of review to the MWA since they “abandoned chapter 49.52 RCW and instead focused on the [MWA] and various common law theories of recov[85]*85ery.” 139 Wn.2d at 831 n.3. Here, Champagne has preserved his claims under all three wage statutes.
¶27 The County argues that Champagne’s prayer for relief seeking damages solely under the WRA effectively excludes the MWA and WPA from the scope of this court’s review. The County reminds the court that notice pleading standards have limits as defined in Berge v. Gorton, 88 Wn.2d 756, 762, 567 P.2d 187 (1977), which states, “[e]ven our liberal rules of pleading require a complaint to contain direct allegations sufficient to give notice to the court and the opponent of the nature of the plaintiff’s claim.” The County also argues that this court should honor Champagne’s “intentional” omission of a request for damages under the MWA and WPA. Suppl. Br. of Resp’t at 8.
¶28 Champagne argues that the totality of his complaint meets the notice pleading rules. He argues that the reference to relief contained within each separate cause of action puts the County on notice of his MWA and WPA claims.14 He also contends that the concluding phrase of his prayer for relief (“[f]or such other relief as the Court deems just [86]*86and equitable”15) sufficiently apprises the County of his request for relief under the MWA and WPA. Reply in Supp. of Pet. for Review at 5.
¶29 Champagne’s complaint does not transgress the liberal bounds of the notice pleading standard. The County argues persuasively that a generic prayer for relief does not provide adequate notice to the opposing party of a particular remedy. However, the entirety of Champagne’s complaint supplies direct allegations sufficient to give notice to both the court and the County that Champagne sought relief under the MWA, WPA, and WRA. See CP at 6-7. Furthermore, Champagne’s allegedly intentional omission of a particular prayer for relief is immaterial. This court has found that the pleader’s intention when drafting the complaint does not control the court’s scope of review. Berge, 88 Wn.2d at 763.16
f 30 We hold that the totality of Champagne’s complaint comports with notice pleading rules and that review of the [87]*87causes of action under the MWA and WPAin addition to the WRA is appropriate.
D. Does delayed payment of wages provide a cause of action under the MWA?
f 31 The MWA provides in pertinent part:
(1) Any employer who pays any employee less than wages to which such employee is entitled under or by virtue of this chapter, shall be liable to such employee affected for the full amount of such wage rate, less any amount actually paid to such employee by the employer, and for costs and such reasonable attorney’s fees as may be allowed by the court. Any agreement between such employee and the employer to work for less than such wage rate shall be no defense to such action.
RCW 49.46.090.
¶32 Champagne encourages the court to consider by analogy federal interpretations of section 207 of the Fair Labor Standards Act of 1938 (FLSA), 29 U.S.C. §§ 201-219, since the FLSA provided the model for the MWA. Champagne cites several district and circuit court cases for the proposition that a delay in payment is tantamount to a failure to pay. However, this analogy is misleading given that federal courts have distinguished the treatment of additional pay from regular pay under the FLSA because the FLSA permits an employer to “delay” payment of overtime to allow for processing.17 See O’Brien v. Town of Agawam, 350 F.3d 279, 298 (1st Cir. 2003) (noting that the secretary of labor has interpreted the FLSA to allow delayed payment of overtime wages to allow for processing). Similarly, the Court of Appeals, Division Two, in Clark v. [88]*88City of Kent, 136 Wn. App. 668, 150 P.3d 161 (2007), surveyed federal case law and found that “[f]ederal law allows for some ‘reasonable’ amount of processing or lag time under the FLSA for irregular pay such as overtime.” Id. at 677 (distinguishing Biggs v. Wilson, 1 F.3d 1537 (9th Cir. 1993), which held that delayed payment of regular wages violated the FLSA) (citing 29 C.F.R. § 778.106). Thus, Champagne’s reliance upon federal law construing the FLSA is misplaced.
¶33 The County argues and the Court of Appeals concluded that SPEEA addressed this issue and determined that since the additional pay was eventually paid, no liability exists under the MWA. In SPEEA, the court held that “in circumstances where an employer paid no compensation whatsoever to an employee, the employee, if not otherwise exempt under the [MWA], could recover wages representing the difference between the statutory minimum wage and what was actually paid.” 139 Wn.2d at 831.
¶34 Consistent with our holding in SPEEA, we hold that the MWA does not provide a cause of action where the employer has actually paid all wages due an employee. Champagne was paid all due regular and additional pay and, thus, does not have a cause of action under the MWA.
E. Does delayed payment of wages give rise to liability under the WPA?
¶35 In pertinent part, the WPA provides that an employer may not withhold wages due an employee at the termination of employment unless required by law, by agreement between the employer and employee, or for medical services. RCW 49.48.010. The WPA also contains a proviso that renders a governing and contrary “labor-management agreement” controlling authority on the issue of payment. Id.
136 Champagne focuses on the following language of the WPA to establish his claim: “ ‘It shall be unlawful for any employer to withhold or divert any portion of an employee’s wages.’ ” Pet. for Review at 13-14 (quoting RCW 49.48.010). [89]*89He further argues that “employees who have had their wages unlawfully withheld in violation of RCW 49.48.010 have a private right of action against the employer.” Pet. for Review at 14 (citing Wingert, 146 Wn.2d at 850).
¶37 The County notes that the WPA is limited in its application. As its language suggests, RCW 49.48.010 applies in the context of termination. Further, RCW 49.48.010 has not been applied to nontermination cases. Pope, 121 Wn.2d at 489 (holding that the trial court erred in granting summary judgment where the plaintiffs had not pleaded that the employer defendant made “improper deductions” at the end of the employment relationship). Like the employees in Pope, Champagne is not claiming that the County made improper deductions at the time of termination. Champagne is a current employee of the County and, therefore, his claim is beyond the scope of RCW 49.48.010.
¶38 Furthermore, a labor-management agreement may trump the provisions of the WPA. RCW 49.48.010. Here, the governing collective bargaining agreement allows for a delay in payment of overtime wages and compensatory time. CP at 135, 188. Therefore, even if RCW 49.48.010 applied (which it does not because Champagne is a current employee), the statute would bar its application to damages arising from delayed payment of overtime wages and compensatory time.
IV. CONCLUSION
¶39 We affirm the Court of Appeals but on different grounds. First, we hold that “delayed” payment of wages beyond the time frame set forth in former WAC 296-128-035 does give rise to employer liability under the WRAbut only where such delay is “willful,” and here it was not willful. Second, we hold that “delayed” payment of wages does not give rise to employer liability under the MWA. Finally, we [90]*90hold that the WPA does not apply outside the termination context.
