Six downtown Chicago hotels walked off the job Friday, two days before the Chicago Marathon, narrowing a strike threat 7,000 workers authorized at 46 properties citywide.

The walkout hit three Marriott-branded hotels — the Sheraton Grand Chicago Riverwalk, The Westin Chicago River North, and The Westin Michigan Avenue Chicago — alongside two Hilton-branded hotels and the Millennium Knickerbocker. Contracts expired August 31 at 44 of the 46 hotels in the bargaining group, leaving current strike scope far below what members approved last month.

UNITE HERE Local 1 President Karen Kent stopped short of naming a trigger for escalation. "We're going to have to do a lot more, whether it's strikes or other actions," she said. Workers at the remaining 40 hotels "could be on strike at any moment," Kent added.

What is actually blocking a deal?

A source familiar with the hotels' bargaining position said talks are stuck on a clause that would extend UNITE HERE representation to a company's other commonly owned or managed hotels across Illinois, Indiana, Wisconsin, and Iowa. Economic terms — wages, health benefits, pensions, and workloads — have not been substantively discussed.

The multi-state organizing clause sits in front of the dollar questions. The union blames the operators. The operators blame the union.

What economics sit underneath the fight?

UNITE HERE Local 1 has framed the dispute around $22.3 billion the union estimates Marriott, Hilton, and Hyatt returned to shareholders over three years. The brands counter that buybacks draw from franchise and licensing fees, not the payroll line, which sits with individual property owners.

That distinction matters because hotel margins are tightening beneath the labor fight. Labor consumed just over half of U.S. hotel operating expenses in 2023, CBRE data shows. U.S. hotel EBITDA fell 2.4% in 2024 and 4.3% in 2025, per Lodging Analytics Research & Consulting.

Members at struck hotels have publicly said rising rents outpace wages. Owners argue that compressed margins leave little room for further increases without trade-offs elsewhere.

Why is Hyatt missing from the strike list?

No Hyatt property appears on the walkout, even though Hyatt carries the largest footprint among the 46 hotels in the bargaining group. The struck mix — three Marriott flags, two Hilton flags, and a Millennium property — concentrates the disruption on the two dominant third-party brand families in downtown Chicago.

What happens next?

Marriott and Hilton said struck hotels have operating plans. Marathon weekend rooms are commanding premium rates operators will work to protect.

Kent declined to identify what economic movement would prompt a wider walkout. With unused authorization at 40 hotels and a multistate representation clause unresolved, the next test arrives at the next bargaining session.
