Collective bargaining agreements for most unionized workers in Cook County and the city of Chicago are set to expire in 2027, raising questions about the future of public-sector wages amid evolving fiscal challenges. Both jurisdictions are grappling with budget constraints shaped by shifting economic conditions and upcoming political transitions.

Currently, city of Chicago employees are slated to receive raises exceeding 3% in 2027, with many union contracts tied to the consumer price index to maintain compensation at or above inflation levels. Cook County workers represented by unions are expected to see wage increases of approximately 4% next year. These increases surpass typical private-sector wage growth, which has slowed nationally to around 3% as of September 2026, while consumer prices rose 3.4% in August.

Cook County’s 2027 budget, valued at $9.7 billion, has been characterized by Board President Toni Preckwinkle as the most challenging since she took office in 2010. Preckwinkle has employed one-time fiscal measures, including expenditure cuts and reserve usage, to avoid tax or fee increases during this election year. However, significant obstacles loom, including substantial federal Medicaid funding reductions and a recent court ruling preventing the county from using $250 million annually from transportation-related revenues to support related operations such as traffic court. Preckwinkle indicated that revenue increases, potentially in the form of property tax hikes, may be unavoidable in 2027, a stance she expressed more clearly and early than in previous years.

Labor negotiations for county workers, representing about 16,125 union members, are scheduled to begin early next year. While details remain confidential, Preckwinkle’s administration has reportedly informed union leaders that conditions will be more constrained going forward. Lanetta Haynes Turner, Preckwinkle’s chief of staff, noted that the county intends to collaborate with labor partners on a feasible plan, implicitly signaling a departure from past wage agreements that guaranteed inflation-beating adjustments.

In the city of Chicago, union contracts covering thousands of workers, including those with the Teamsters, the American Federation of State, County and Municipal Employees, and the Fraternal Order of Police, expire by mid-2027, some as early as June. Mayor Brandon Johnson, seeking reelection in February 2027 and known for his pro-labor stance, has historically approved generous wage increases for public-sector unions. Contracts for Chicago Public Schools teachers, negotiated during Johnson’s tenure, include raises between 4% and 5% annually through 2028, with average teacher salaries projected to reach six figures. The city has already sought additional state funding to manage related fiscal shortfalls.

Johnson also authorized increased pay raises for police officers ahead of contract expirations, lifting scheduled raises and setting increases between 3% and 5% through mid-2027. Critics argue that such agreements have contributed to budget deficits and placed pressure on state and local resources.

It remains uncertain how negotiations for city workers’ contracts will proceed, especially if Johnson is not reelected. Observers emphasize the importance of clear fiscal messaging from city leadership to union representatives, akin to the approach taken by Cook County officials. The prevailing consensus is that the era of rising public-sector union wage hikes that exceed inflation may be unsustainable, particularly given the financial pressures on taxpayers and government budgets.

As both Cook County and Chicago prepare for labor contract renewals amid constrained budgets and upcoming elections, the negotiation outcomes will likely have significant implications for public finances, union members, and residents alike.
