Chicago's Watchdog Warned in 2013. It Paid $26.5M Anyway

The City of Chicago Office of Inspector General (OIG) -- the independent oversight office empowered under the City's Municipal Code to audit and investigate City operations -- has found⧉ that between January 1, 2020 and December 31, 2024, Chicago paid $26,528,587 in overtime to 1,072 employees who, based on their federal Fair Labor Standards Act (FLSA) classification and their union contracts, may not have been legally entitled to it.▸ Under the FLSA, most workers must be paid time-and-a-half after 40 hours in a week -- but employees classified as "exempt" (typically executives, administrators, and professionals) are cut out of that requirement entirely, unless a collective-bargaining agreement (CBA) separately grants them overtime pay. OIG cross-checked the City's own list of which of its 1,162 job titles are FLSA-exempt against the CBAs covering those titles, then matched that against five years of actual payroll data -- and found the City paying overtime it had no legal basis to pay, over and over, to more than a thousand people.

This is not a new discovery.▸ In 2013, OIG tried to audit the City's overtime payments for FLSA compliance and couldn't -- the City hadn't even finished determining which of its own job titles were exempt. OIG instead sent an advisory to the Mayor's Office flagging the gap. At the time, the Department of Human Resources (DHR) said it had put its Classification and Compensation Division in charge of the problem and would build a citywide policy. Twelve years later, meeting with OIG again in September 2025, DHR told a different story: "there had been many past discussions of ensuring that FLSA statuses were consistent within job titles," but no solution had been implemented. OIG's own conclusion states it plainly: "Twelve years after first bringing this issue to DHR's attention, OIG concludes that the City continues to pay overtime to potentially ineligible employees." An open finding that sits for over a decade isn't a paperwork lag -- it means nobody with the authority to fix it was ever made to.

The $26.5 million spread across 27 City departments, boards, and offices -- but not evenly.▸ Five of them, led by the Chicago Fire Department's $6.9 million, account for $20,816,309, or 78.5%, of the total. Public-safety and infrastructure agencies with round-the-clock staffing needs -- Fire, the Office of Emergency Management and Communications, Water Management, Police -- dominate the list, alongside the Public Library, whose 308 potentially affected employees make it the single largest headcount even though its dollar total is comparatively small. OIG built in real conservatism here: it separately identified 38 employees, covered by CBAs that specifically allow weekend overtime, who were paid $1,073,137 over the same period -- and excluded all of it from the $26.5 million figure because the City's payroll data doesn't record which day of the week the hours were actually worked. And 91.2% of the flagged total, $24,202,590, ran through just three straightforward overtime pay codes (base rate, 1.5x, and 2x) -- not the ambiguous codes OIG couldn't fully define, which means the bulk of the finding rests on the clearest, least-disputable data in the set.

Eighteen individual employees were each paid between $250,000 and $700,000 in potentially ineligible overtime over the five years -- $6,517,778 combined, or 24.6% of the citywide total, concentrated in roughly 1.7% of the 1,072 affected employees.▸ The single largest recipient, a Deputy District Chief in the Fire Department, collected $687,253; two more Deputy District Chiefs cleared $595,669 and $593,419. Averaged across all 1,072 employees, the payout works out to about $24,747 apiece -- but that average obscures the shape of the problem: this wasn't small, scattered overpayments across the workforce, it was real money concentrated in a small number of high-overtime roles inside a handful of departments.

The mechanics explain why this isn't a one-time mistake.▸ DHR's citywide list classifies 642 of the City's 1,162 job titles as exempt from any overtime pay at all. But OIG found 137 titles where employees holding the identical job carried inconsistent FLSA statuses -- some flagged eligible, others not -- meaning the City was, by its own classification system, simultaneously paying overtime it should have withheld and withholding overtime it should have paid, within the same job title. DHR told OIG that departments can update an employee's FLSA status when they change positions but "may forget to do so," which is the closest the report comes to naming a root cause: a classification system with no enforced mechanism to keep department-level payroll data matched to DHR's own master list.

OIG's advisory landed five months after Chicago's own 2026 Budget Forecast⧉ projected the City's Corporate Fund -- its core day-to-day operating budget -- would close 2025 with a $146.0 million deficit and face a $1,149.3 million gap in 2026, widening further to $1,166.3 million in 2027 and $1,225.9 million in 2028 under the City's own base-case assumptions.▸ Personnel costs are the single largest driver of that 2026 growth, projected to rise $629.0 million -- and the forecast document itself names overtime pay, alongside salaries, pensions, healthcare, and workers' compensation, as one of the personnel-cost categories "account[ing] for the majority of total Corporate Fund expenditures ... and [is] one of the largest drivers of expense growth."

The same document's own year-end accounting for 2025 notes that personnel services finished $14.3 million under budget overall -- "partially offset by elevated overtime costs."▸ The $26,528,587 OIG flagged as potentially unlawful is itself equal to 18.17% of the entire FY2025 deficit -- not the deficit's cause, but money the City had no legal basis to spend at all, inside a budget with no room to spend money it doesn't have to.
