ON REMAND
PER CURIAM.
Plaintiff appeals by leave granted from an opinion and order of the Workers' Compensation Appeal Board upholding defendants' unilateral reduction of plaintiff's benefit pursuant to Gusler v Fairview Tubular Products, 412 Mich 270; 315 NW2d 388 (1981). We affirm.
Plaintiff was employed part-time, earning $60.21 *77 a week. After she suffered a work-related injury, she was awarded what the Bureau of Workers' Disability Compensation determined to be the statutory minimum benefit under its understanding of MCL 418.351; MSA 17.237(351), MCL 418.355; MSA 17.237(355), and Jolliff v American Advertising Distributors, Inc, 49 Mich App 1; 211 NW2d 260 (1973). Jolliff recognized an adjustable minimum level of compensation in each dependency category parallel to the statutory adjustable maximum level. Plaintiff was awarded $57 a week instead of $40.14 a week, which was two-thirds of her weekly wage loss of $60.21. Both parties filed appeals with the WCAB, which were later dismissed. Defendants paid benefits of $57 a week until December 30, 1981, when they unilaterally reduced benefits to $40.14 a week, two-thirds of plaintiff's weekly wage loss, on the basis of Gusler, supra. In Gusler, the Court held that the adjustment provisions of § 355 of the Workers' Disability Compensation Act, MCL 418.101 et seq.; MSA 17.237(101) et seq., apply only to the maximum, and not the minimum, weekly rates established in § 351(1). Gusler overruled Jolliff, in which it was held that the minimum compensation rates established by § 351 were adjustable, along with the maximum compensation rates, under § 355.
Plaintiff appealed to the WCAB, claiming res judicata. The WCAB upheld defendants' unilateral reduction of plaintiff's weekly wage loss benefits, relying on Juncaj v C & H Industries, 161 Mich App 724; 411 NW2d 839 (1987), aff'd 431 Mich 632; 433 NW2d 787 (1988), holding that res judicata did not bar defendants' unilateral reduction of plaintiff's wage loss benefit. This Court denied plaintiff's application for leave to appeal. Plaintiff then sought leave in the Michigan Supreme Court, which, in lieu of granting leave, remanded to the *78 Workers' Compensation Appeal Board for further proceedings consistent with Riley v Northland Geriatric Center (After Remand), 431 Mich 632; 433 NW2d 787 (1988). 432 Mich 882 (1989). In Riley, the Court decided that the doctrine of res judicata did not bar Gusler's correction of Jolliff's error with respect to "benefits due and not yet paid." The Riley Court held that "Gusler applies to all benefits due or paid after December 30, 1981, the date of our opinion in that case, including benefits paid pursuant to awards entered prior to that date." The Court remanded this matter to the WCAB "to determine (1) whether the unilateral reduction of benefits was improper; and (2), if so, what, if any, remedy should be provided" in light of Riley, supra.
On remand, the WCAB determined that the defendants' unilateral reduction of benefits was proper and, therefore, no remedy was required. Plaintiff applied for leave to appeal, asserting that the WCAB committed error requiring reversal when it upheld defendants' unilateral reduction of plaintiff's wage loss benefits contrary to 1980 AACS, R 408.40 (Rule 10), which requires another administrative order before an award is reduced. The Court of Appeals denied the application for leave. However, the Supreme Court, in lieu of granting leave, remanded to the Court of Appeals for consideration as on leave granted. 436 Mich 883 (1990).
Rule 10 provides:
(1) When compensation is being paid under an order or award of the administrative law judge or appeal board, compensation shall not be discontinued or reduced without a further order or award, except as provided in subrules (3) and (4) of this rule.
*79 In the present case, we determine that defendants may unilaterally reduce plaintiff's wage loss benefits pursuant to Riley and Gusler's correction of Jolliff's error without a prereduction hearing under Rule 10. We determine that a prereduction wage loss benefit hearing is not required because of the unique legal circumstances of this particular case. In Gusler, the Court did not diminish any of plaintiff's existing rights. It merely determined that Jolliff had improperly interpreted the WDCA by increasing minimum compensation rates in tandem with maximum compensation rates. In Gusler, the Court simply voided awards of benefits to the extent that they exceeded the statutorily authorized amount of two-thirds of the average weekly wage of a worker injured between 1969 and 1981.
In Gusler, supra at 298, the Court also specified how its holding would be implemented.
In the interest of fairness we do not believe our holding should affect any disability compensation payments already made. Consequently, no recipient will be obligated to repay sums already received by reason of the erroneous computation formula we have nullified today. However, any benefits due and not yet paid or to be awarded after the date of this opinion shall be in accord with this ruling.
In Riley, supra at 636, 649, the Court affirmed the holding of Gusler and stated:
The principal issue raised is whether the directed correction of Jolliff's error with respect to "benefits due and not yet paid" after Gusler is precluded by the doctrine of res judicata. We conclude that res judicata is not a bar. We further hold that Gusler applies to all benefits due or paid *80 after December 30, 1981, the date of our opinion in that case, including benefits paid pursuant to awards entered prior to that date.
* * *
We conclude that the implementing language means what it says, and that payments after December 30, 1981, are to be adjusted in accord with Gusler, whether the award was made before or after Gusler.

Thus, both Gusler and Riley require benefit payments at the level authorized by statute.
Benefits are awarded on the basis of a finding of fact with respect to plaintiff's average weekly wage on the date of injury. The accuracy of that factual finding is not questioned in this appeal. Rather, the issue is whether the bureau must calculate two-thirds of the established average weekly wage after a prereduction hearing under Rule 10 or whether the benefits payor may unilaterally recalculate the award at two-thirds of the average weekly wage as statutorily authorized under the former § 351.
Because the average weekly wage in this case is already indisputably determined, allowing the benefits payor to unilaterally calculate two-thirds of the average weekly wage simply does not impair or undermine any significant administrative determination in this case. However, in cases involving issues other than a simple mathematical calculation, failure to apply Rule 10 may undermine and impair the integrity and validity of the administrative process.
Presumably, the purpose of a prereduction hearing is to accurately resolve factual and legal disputes and prevent employers from coercing settlements by illegitimately reducing or terminating benefits. In the absence of a factual and legal *81 dispute or the threat of illegitimate coercion, the rationale for Rule 10 does not apply in this case.
Moreover, the defendants' unilateral reduction of benefits to a level statutorily authorized does not implicate any constitutional issues of due process. In Franks v White Pine Copper Division, 422 Mich 636, 654; 375 NW2d 715 (1985), the Court stated:
Workers' compensation benefits are social-welfare income-maintenance benefits....
Income-maintenance benefits payable under a legislatively mandated social welfare program are not property protected by the Due Process Clause, the Contract Clause, or the Takings Clause from substantive change by subsequent legislation....
Whatever property interest plaintiff may wish to safeguard from an erroneous calculation of two-thirds of the average weekly wage is adequately protected by her right to petition the bureau for a postreduction hearing.
In this case, defendants unilaterally adjusted plaintiff's benefits after Gusler was decided to the level authorized by statute. Plaintiff does not dispute the accuracy of defendants' redetermination of her average weekly wage or raise any legal issues concerning the validity of Riley or Gusler overruling Jolliff; nor does plaintiff allege that defendants are coercing her to compromise any of her substantive rights. We find that defendants' unilateral reduction of plaintiff's wage loss benefits to the statutorily authorized level was appropriate under the unique and limited circumstances of this case and that plaintiff has adequate due process safeguards under the WDCA to correct any factually erroneous reduction, which does not appear to exist here.
Affirmed.
