Opinion
GILBERT, Acting P. J.An injured worker receives vocational rehabilitation maintenance allowance (VRMA). Her employer unreasonably delays paying advances against permanent disability (PDA) per Labor Code section 139.5. In this case of first impression, we hold that the 10 percent penalty under Labor Code section 5814 should be assessed against permanent disability (PD).
Victoria Kopitske (Kopitske) petitions for review of the order of the Workers’ Compensation Appeals Board (WCAB) denying reconsideration of its ruling that the penalty assessed for unreasonable delay in paying PDA should only be against VRMA supplemented by PDA, and not against PD. *627We annul the order and direct the WCAB to enter a new order assessing the penalty against PD.
Facts
Kopitske suffered an industrial injury. She received $372 per week as temporary disability (TD). Kopitske chose to enter vocational rehabilitation (VR) and received vocational rehabilitation temporary disability (VRTD) payments of $372 per week. Her condition became permanent and stationary (P&S). Accordingly, she was no longer eligible for TD payments. (Lab. Code, § 139.5, subd. (c).)1 She continued to request VR services, making her eligible to receive VRMA. (§ 139.5, subd. (c).) She began receiving VRMA at the statutory rate of $246 per week.
Kopitske requested receipt of the additional amount of $126 per week as an advance from her PD (PDA) so that she would receive two-thirds of her average weekly earnings as of the date of injury. (§ 139.5, subd. (d)(1) & (2).)
Her employer’s workers’ compensation carrier, Safeco Insurance Company (Safeco), delayed providing PDA for 55 days. The workers’ compensation judge found that the delay was unreasonable, but ruled that the 10 percent section 5814 penalty would be assessed only against VRMA benefits including PDA, and not against PD.
Because Kopitske had received VRMA of $11,300 and PDA of $5,800 for a total of $17,100, the 10 percent penalty assessed was $1,710. Kopitske is entitled to PD of $102,267. If the 10 percent penalty had been applied against PD, the penalty would be $10,226.70.
The WCAB denied reconsideration of the decision and Kopitske petitioned this court for review. We granted the petition to consider whether the penalty should be assessed against VRMA or PD. Because the penalty resulted from unreasonable delay in paying advances from PD, the penalty must be assessed against PD, not VRMA.
Discussion
Respondents argue that the purpose of section 139.5, subdivision (d)(2), is wage replacement. Therefore, like TD, penalties for delay in paying advances from PD should be assessed only against VRMA supplemented by PDA. Kopitske argues that because the specific class of benefits *628from which payment was unreasonably delayed is PD, the penalty should be assessed against PD. We agree with Kopitske.
The provisions of workers’ compensation law . . shall be liberally construed by the courts with the purpose of extending their benefits for the protection of persons injured in the course of their employment.” (§ 3202.) It is axiomatic that courts must liberally construe the penalty provision of section 5814 to protect injured workers. (Avalon Bay Foods v. Workers’ Comp. Appeals Bd. (1998) 18 Cal.4th 1165, 1173-1174 [77 Cal.Rptr.2d 552, 959 P.2d 1228].)
Section 5814 specifies, in pertinent part, “When payment of compensation has been unreasonably delayed or refused, ... the full amount of the order, decision or award shall be increased by 10 percent.” Section 5814 applies to virtually every type of benefit provided by workers’ compensation laws. (§ 3207; Avalon Bay Foods v. Workers’ Comp. Appeals Bd., supra, 18 Cal.4th at p. 1173, fn. 3; State of California v. Workers’ Comp. Appeals Bd. (1996) 44 Cal.App.4th 128, 139-140 [51 Cal.Rptr.2d 606].)
In Gallamore v. Workers’ Comp. Appeals Bd. (1979) 23 Cal.3d 815, 827 [153 Cal.Rptr. 590, 591 P.2d 1242], our Supreme Court held that under section 5814, multiple 10 percent penalties apply to unreasonable delay in making PD payments, in obtaining an unauthorized credit for asserted overpayments of TD and in delaying reimbursement of travel expenses. Gallamore concluded that “the penalty [under section 5814] is to be computed by assessing 10 percent of the entire amount ultimately awarded for the particular class of benefit which has been unreasonably delayed or withheld.” (23 Cal.3d at p. 827, italics added; accord, Rhiner v. Workers’ Comp. Appeals Bd. (1993) 4 Cal.4th 1213, 1219, 1220, 1225, 1227 [18 Cal.Rptr.2d 129, 848 P.2d 244].)
In Avalon Bay Foods v. Workers’ Comp. Appeals Bd., supra, 18 Cal.4th at page 1171, our Supreme Court explained that where “ ‘. . .an award is readily severable into the different classes or categories of compensation as defined in the Workers’ Compensation Act. . . the penalty is to be assessed against only the amount awarded for the particular benefit of the kind delayed or refused.’ ” (Quoting Gallamore v. Workers’ Comp. Appeals Bd., supra, 23 Cal.3d at p. 824.) “ ‘. . . Thus, if any part of a specific benefit has been delayed or withheld, the penalty is imposed against the entirety of that benefit.’ ” (18 Cal.4th at p. 1171, quoting Gallamore, supra, at p. 827.) In Avalon Bay Foods, the court held that medical transportation benefits fall within the same class of compensation as medical treatment benefits. (18 Cal.4th at pp. 1171-1172.)
*629Furthermore, the penalty is assessed against all amounts due before or after the award for the particular class of benefit, whether or not timely paid, and regardless of the amount involved. (Rhiner v. Workers’ Comp. Appeals Bd., supra, 4 Cal.4th at pp. 1218-1219; Gallamore v. Workers’ Comp. Appeals Bd., supra, 23 Cal.3d 815.)
Respondents argue that it would be unduly harsh to impose the penalty on the full amount of PD when the unreasonably delayed payments constitute a small amount advanced against PD. Rhiner rejected this argument stating, “The express language of the statute . . . compels the conclusion . . . that the penalty must be assessed on ‘the entire amount ultimately awarded for the particular class of benefit which has been unreasonably delayed or withheld.’ ” (Rhiner v. Workers’ Comp. Appeals Bd., supra, 4 Cal.4th at p. 1225, citing section 5814 and quoting Gallamore v. Workers’ Comp. Appeals Bd., supra, 23 Cal.3d at p. 827.) “ ‘. . . Thus, if any part of a specific benefit has been delayed or withheld, the penalty is imposed against the entirety of that benefit.’” (4 Cal.4th at p. 1220, quoting Gallamore, supra, at p. 827; accord, Avalon Bay Foods v. Workers’ Comp. Appeals Bd., supra, 18 Cal.4th at p. 1171.) It is true that in this case the assessment against PD results in a higher penalty, but there are many cases in which VRMA or VRMA plus PDA exceed PD.
In Rhiner, the employer unreasonably required the worker to travel about 200 miles to receive medical treatment. The WCAB applied the 10 percent penalty after deducting preaward payments. Rhiner annulled the decision, holding that the penalty must be applied to the full amount of the award for the class of compensation at issue, without deduction for timely preaward payments. (Rhiner v. Workers’ Comp. Appeals Bd., supra, 4 Cal.4th at pp. 1215-1217, 1227-1228.)
Rhiner acknowledged that a large penalty may result from the employer’s unreasonable delay in paying a small amount of benefits to the injured employee. Rhiner explained, however, that a monetary amount that is of little consequence to an employer or carrier may be disastrous to an injured worker struggling to obtain treatment and to pay basic household expenses. We are not at liberty to second-guess the policy determination made by the Legislature. (Rhiner v. Workers’ Comp. Appeals Bd., supra, 4 Cal.4th at p. 1226. )
As here, Rhiner concerned benefits that apply only to injuries occurring on or after January 1, 1990. The 1990 amendments shortened time limits for compensation payments and added new penalties for delay in benefit payments. (Rhiner v. Workers’ Comp. Appeals Bd., supra, 4 Cal.4th at pp. *6301226-1227.) The Legislature however did not amend section 5814. (4 Cal.4th at p. 1227.) Accordingly, Rhiner concluded that “. . . the Legislature has indicated its continuing concern with the problem of delay or refusal by employers to timely pay compensation benefits to injured employees.” (Ibid.)
The workers’ compensation system provides separate classes of indemnity for temporary and permanent disabilities. (Edgar v. Workers’ Comp. Appeals Bd. (1998) 65 Cal.App.4th 1, 10-11 [76 Cal.Rptr.2d 83]; Western Growers Ins. Co. v. Workers’ Comp. Appeals Bd. (1993) 16 Cal.App.4th 227, 235 [20 Cal.Rptr.2d 26].) A disability cannot be both permanent and temporary at the same time. (Western Growers Ins. Co., supra, at p. 235.) For purposes of the issue before us, there are four distinct classes of benefits: TD, VRTD, VRMA and PD.
TD is the immediate incapacity to work due to an industrial injury that is reasonably expected to be cured or materially improved with proper medical treatment. (Western Growers Ins. Co. v. Workers Comp. Appeals Bd., supra, 16 Cal.App.4th 227, 235; Chavira v. Workers’ Comp. Appeals Bd. (1991) 235 Cal.App.3d 463, 473 [286 Cal.Rptr. 600].) The class of TD serves only as wage replacement during the injured worker’s healing period. It is payable at two-thirds of the worker’s average weekly earnings. (§ 4653; Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at pp. 10-11; Ritchie v. Workers’ Comp. Appeals Bd. (1994) 24 Cal.App.4th 1174, 1179 [29 Cal.Rptr.2d 722]; Maples v. Workers’ Comp. Appeals Bd. (1980) 111 Cal.App.3d 827, 836 [168 Cal.Rptr. 884]; and see 1 Hanna, Cal. Law of Employee Injuries and Workers’ Compensation (rev. 2d ed. 1999) § 7.01 [1], pp. 7-4-7-5.)
The injured employee may go into VR. (Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at p. 11.) The purpose of VR under workers’ compensation is to restore an injured employee to suitable employment. (Moyer v. Workmen’s Comp. Appeals Bd. (1973) 10 Cal.3d 222, 232 [110 Cal.Rptr. 144, 514 P.2d 1224]; Edgar, supra, at p. 11.) It serves to get the disabled worker from “ ‘ “the bed to the job.” ’ ” (Moyer, supra, at p. 232; Edgar, supra, at p. 11.)
In the words of section 4635, subdivision (d), “ ‘Vocational rehabilitation services’ means those services required to determine if an employee can reasonably be expected to return to suitable gainful employment and those services reasonably necessary to provide an employee with the opportunity to return to suitable gainful employment. These services may include, but are not limited to, vocational and medical evaluation, counseling, job analysis, job modification assistance, retraining, including on-the-job training or *631training for alternative employment, formal training, academic instruction, and job placement assistance.”
During the initial period of VR, the worker remains temporarily disabled and the benefits are received from VRTD. (See Jimenez v. Workers’ Comp. Appeals Bd. (1991) 1 Cal.App.4th 61, 64 [1 Cal.Rptr.2d 660]; Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at p. 12 [distinguishing TD].) The worker continues to receive two-thirds of his or her average weekly earnings until becoming P&S.
Section 139.5, subdivision (c), states, in pertinent part, “When an employee is determined to be medically eligible and chooses to participate in a vocational rehabilitation program, he or she shall continue to receive temporary disability indemnity payments only until his or her medical condition becomes permanent and stationary and, thereafter, may receive a maintenance allowance.”
When the employee’s condition has reached maximum improvement or it has become stationary for a reasonable period of time, the worker is considered to be P&S. (Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at pp. 10-11.) When the employee’s condition has become P&S, the worker is considered to have a permanent disability. (Id., at p. 10; Western Growers Ins. Co. v. Workers Comp. Appeals Bd., supra, 16 Cal.App.4th at p. 235.) “When a disability changes from temporary to permanent, the permanent disability is considered a new and further disability.” (Western Growers Ins. Co., supra, at p. 235.) Thus, when a worker is deemed P&S, he or she is entitled to PD and TD payments cease. (Ritchie v. Workers’ Comp. Appeals Bd., supra, 24 Cal.App.4th at pp. 1179-1180; Edgar, supra, at p. 11.)
Effective January 1990, when an eligible, injured worker becomes P&S, the worker may continue in VR even though the worker is permanently disabled and is entitled to receive PD benefits. (§ 139.5, subds. (c) & (d).) The status of a worker who opts to remain in VR after becoming P&S is called VRMA. (§ 139.5.) “Rehabilitation maintenance allowance payments shall begin after the employee’s medical condition becomes permanent and stationary . . . .” (§ 139.5, subd. (c); see also Jimenez v. Workers’ Comp. Appeals Bd., supra, 1 Cal.App.4th at p. 64.) The worker no longer receives TD payments. Indeed, section 139.5, subdivision (d)(2), provides, in pertinent part, that “[I]n no event shall temporary disability indemnity and maintenance allowance be payable concurrently.” (Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at p. 13, fn. 7.)
Under VRMA, the worker receives “additional living expenses necessitated by the vocational rehabilitation services, together with all reasonable *632and necessary vocational training, . . . but iñ no event shall the expenses, counseling fees, training, maintenance allowance, and costs associated with . . . vocational rehabilitation services incurred . . . except temporary disability payments, exceed sixteen thousand dollars ($16,000).” (§ 139.5, subd. (c).)
The worker also receives a maintenance allowance. “The amount of the maintenance allowance due under subdivision (c) shall be two-thirds of the employee’s average weekly earnings at the date of injury payable as follows: [¶] (1) The amount the employee would have received as continuing temporary disability indemnity, but not more than two hundred forty-six dollars ($246) a week . ... [¶] (2) At the employee’s option, an additional amount from permanent disability indemnity due or payable, sufficient to provide the employee with a maintenance allowance equal to two-thirds of the employee’s average weekly earnings at the date of injury . . . .” (§ 139.5, subd. (d)(1) & (2); Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at p. 13.)
Thus, the standard maximum weekly payment for VRMA is only $246. The worker is permitted to “borrow” from PD to receive two-thirds of prior wages if he or she chooses to continué in VR. The additional amounts are advances against the final PD amount the worker is entitled to receive and are not counted against the $16,000 cap for VR benefits. (§ 139.5, subd. (d)(2).) A worker may remain on VRMA for only 52 weeks in the aggregate. (§ 139.5, subd. (c).)
PDA is not counted against the $16,000 payment cap for VR expenses and services. PDA is credited against and subtracted from PD owed. Accordingly, the class of benefits which the carrier unreasonably delayed paying here is PD. (See § 4909.) The PD class of benefits does not change because it is paid in advance. This is true even though the purpose of the advances is to supplement income while the worker is receiving VRMA. Some workers would not be entitled to obtain advances against PD while in VR because their prior earnings were equal to or less than $246 per week.
PD compensates for residual handicap and/or impairment of function after maximum recovery has been attained and also serves “to assist the injured worker in his adjustment in returning to the labor market.” (Maples v. Workers’ Comp. Appeals Bd., supra, 111 Cal.App.3d at p. 836; see also Ritchie v. Workers’ Comp. Appeals Bd., supra, 24 Cal.App.4th at pp. 1179-1180.) PD benefits “ ‘are in addition to any temporary disability benefits that may be paid or owing.’ ” (Edgar v. Workers’ Comp. Appeals Bd., supra, 65 Cal.App.4th at p. 11.)
*633Ritchie considered whether an injured municipal police officer is entitled to receive VRMA after the effective date of disability retirement from the Public Employees’ Retirement System. (Ritchie v. Workers’ Comp. Appeals Bd., supra, 24 Cal.App.4th at pp. 1177-1178.) Ritchie held that such individuals are not entitled to VRMA under such circumstances. Ritchie reasoned that the Legislature intended that VRMA is a form of TD, and is not a new benefit despite legislative materials stating otherwise. (See id., at p. 1185.) To the extent Ritchie may conflict with this- opinion, we respectfully disagree.
Ritchie acknowledged that the 1994 amendments to section 139.5 “arguably” evidence a view that VRMA and TD “are substantially different.” (Ritchie v. Workers’ Comp. Appeals Bd., supra, 24 Cal.App.4th at p. 1185, fn. 9 [pointing out that the 1994 legislation capped payment of VR services at $16,000, limited the time period for which VRMA may be received, and excluded TD payments from the cap].) Ritchie explained that VRMA begins when the worker who is enrolled in VR becomes P&S, and that VRMA is paid in lieu of TD. (Id., at p. 1182.) Ritchie also acknowledged that VRMA payments are set at a lower minimum than TD benefits, “before any allowable supplementation with [PD] benefits.” (Id., at p. 1185.) Thus, Ritchie differentiated between TD, basic VRMA, and PDA.
“'“ ‘Wide discretion is vested in the Legislature in making the classification[s] and every presumption is in favor of the validity of the statute; the decision of the Legislature as to what is a sufficient distinction to warrant the classification will not be overthrown by the courts unless it is palpably arbitrary and beyond a rational doubt erroneous.’ ” ’ ” (Ritchie v. Workers’ Comp. Appeals Bd., supra, 24 Cal.App.4th at p. 1192, quoting Saal v. Workmen’s Comp. Appeals Bd. (1975) 50 Cal.App.3d 291, 300 [123 Cal.Rptr. 506].)
We do not view PDA as a hybrid benefit. PDA is simply an advance from and against PD. Accordingly, when the employer or carrier unreasonably delays paying advances on PD, the penalty should be assessed against PD, not against VRMA as “supplemented” by PDA.
Our Supreme Court has emphasized what the Legislature has said: to liberally construe benefits in favor of the worker. The Legislature has created distinct classifications for purposes of receipt of various benefits by injured workers, including TD, VRTD, VRMA and PD. (See 1 Hanna, Cal. Law of Employee Injuries and Workers’ Compensation, supra, § 10.40[6][a], pp. 10-66.1 to 10-66.2; 2 Hanna, Cal. Law of Employee Injuries and Workers’ Compensation, supra, § 35.11[1], pp. 35-22 to 35-23; id., § 35.11[2][b], pp. 35-25 to 35-26.)
*634The dissent suggests that the majority opinion will encourage employees to ask for PDA in every case in the hope that a late payment will result in a large penalty. We reject this jaundiced appraisal of injured employees. If anything, our opinion ensures that compensation benefits be paid promptly.
The decision of the WCAB to deny reconsideration is annulled. We direct the WCAB to set aside and vacate its ruling and to order the 10 percent penalty payments to be assessed against PD in accordance with this opinion.
The parties are to bear their own costs.
