Hyatt and Hilton properties in Chicago have reached tentative contract agreements with the union representing hotel workers, Unite Here.

The Hilton deal came on the day that contracts were set to expire, August 31. The agreement covers some 2,300 workers at four Hilton properties in the city, including the Hilton Chicago, Hilton O’Hare Airport, The Drake, and the Palmer House Hilton. The parties agreed to a three-year deal that includes improved pay, pension, and healthcare provisions, according to Unite Here. Further information was not available at press time.

Hyatt settled just three days after the contract expired on September 3. The agreement covers 1,900 workers at four Hyatt hotels, including the Hyatt Regency Chicago, Hyatt Regency O’Hare, Hyatt Regency McCormick Place, and the Park Hyatt Chicago. Further details of the agreement were not available at press time.

Contracts remain unsettled with the Starwood chain and its five hotels in Chicago. Talks between Starwood and Unite Here officials are ongoing. Another 11 properties, including the Ritz-Carlton and Fairmont, have signed “me-too” agreements with the union, meaning those hotels will adopt the same terms negotiated by Starwood, according to Unite Here.

Negotiations with two other hotels, the Allerton Crowne Plaza and Hotel Raffaello, have been delayed.
