The Illinois Appellate Court recently ruled on a significant pension calculation dispute affecting retired state employees. The court's decision, issued on October 16, 2026, clarifies how payments for accumulated unused vacation and sick time will be treated in calculating retirement annuities. This ruling impacts several retired employees of the Illinois State Board of Education (ISBE) who are appealing decisions made by the State Employees' Retirement System (SERS).
The case, Wancket v. State Employee Retirement System of Illinois (docket number 1-23-2256), centers on whether bimonthly payments for unused sick and vacation days should be included in the calculation of final average compensation used to determine retirement annuities. The court's ruling is crucial for the plaintiffs, who argue that these payments should not be classified as "lump sum salary payments" and thus should be considered in their pension calculations.
Background
The plaintiffs in this case include Mark Wancket, Kimberly Beachy, Sally Cray, Carl Holman, Elizabeth Minder, Teralandur Venkatesh, and Dennis Williams. They are all retired employees of ISBE and receive pensions from SERS, which is managed by the Board of Trustees of the State Employees’ Retirement System of Illinois. Each plaintiff is challenging administrative decisions made by SERS, which stated that payments for accumulated unused vacation and sick leave should be excluded from the calculation of their final average compensation.
The dispute arose after SERS discovered that ISBE had been reporting payments for accumulated unused vacation and sick days as part of employees' base pay. This misreporting led to an overestimation of pension benefits for retirees, prompting SERS to adjust the pension calculations and reduce the annuities of affected retirees. The plaintiffs argue that they relied on the initial calculations and that the payments should not be classified as lump sum payments when made in installments.
Mark Wancket, one of the plaintiffs, retired in 2011 after 32 years of service. He had taken advantage of an accelerated compensation plan that allowed him to liquidate unused vacation and sick days, which increased his monthly salary and ultimately his pension benefits. However, SERS later determined that these payments were improperly included in the pension calculation and sought to rectify the situation by reducing his pension and requiring repayment of overpayments.
The Ruling
The Illinois Appellate Court ruled in favor of SERS, affirming the agency's interpretation of the Pension Code. The court determined that the bimonthly payments for unused vacation and sick leave are indeed classified as "lump sum salary payments" and are therefore excluded from the calculation of final average compensation. Justice Pucinski delivered the judgment, with Justices Hyman and C.A. Walker concurring.
The court stated, "We find that the bimonthly payments for (i) vacation and (ii) accumulated unused sick leave are 'lump sum salary payments' as installment payments towards a known and definite sum owing and are thus properly excluded from the meaning of 'compensation' under section 14-108."
The court emphasized that the statutory language of the Pension Code clearly defines compensation and excludes lump sum payments for vacation and sick leave. The decision highlighted the legislative intent behind the exclusion, which aims to prevent pension spiking—an issue that arises when employees artificially inflate their pension benefits by receiving large payouts in their final years of employment.
Impact
This ruling has significant implications for retirees and the administration of pension benefits in Illinois. It reinforces the interpretation that payments for unused vacation and sick time, even when made in installments, are not considered part of the final average compensation for pension calculations. This decision may deter similar claims from other retirees who might seek to include these payments in their pension calculations.
The court's ruling also underscores the importance of adhering to the definitions outlined in the Pension Code to maintain the integrity of the pension system. By affirming SERS's interpretation, the court aims to uphold the legislative intent to prevent the manipulation of pension benefits, which has been a growing concern in Illinois due to underfunding issues.
What's Next
The plaintiffs in this case can appeal the ruling to the Illinois Supreme Court if they choose to pursue further legal action. However, details regarding any related cases or potential appeals were not available in the court filing. The outcome of this case may also influence future pension-related disputes involving similar issues of compensation classification.
