Unite Here Local 1 is a Unite Here (sometimes styled UNITE HERE or Unite HERE) affiliated labor union based in Chicagoland and Northwest Indiana.

Critics of Emanuel noted that this endorsement from Unite Here was strange. Emanuel was far from the furthest-left candidate and has used foul language to address concerns of unions. While serving in the Obama administration, he dismissed the concerns of the United Auto Workers union by exclaiming “f—- the UAW,” according to the book Overhaul by former Obama administration advisor Steve Rattner.  Emanuel also said “F—- you, Lewis,” during a sit-down with the former president of the Chicago Teachers Union, Karen Lewis. 
Unite Here Local 1 reached a labor agreement with Hilton Worldwide in 2011 after the union began negotiating contracts in 2009. Unite Here settled coverage for 1,600 workers at the Drake, Chicago Hilton, Palmer House Hilton, and Hilton O’Hare. 
The union also led other strikes against Hyatt Hotels. The strikes began in 2011 due to Hyatt Hotels’ use of subcontracting, outsourcing, and alleged abuse of its workers.  During strikes against Hyatt Hotels in 2012, Unite Here Local 1 president Henry Tamarin attacked the politically connected Pritzker family, who owns the hotel chain, by claiming the family was not doing what was “fair and just” by appealing property tax, despite acknowledging it was legal to do so. 
Unite Here Local 1 called a city-wide strike across 25 hotels in Chicago on September 7, 2018. Approximately 6000 employees on strike at the time were represented by the union.  Hotels such as the Hyatt Regency Chicago, JW Marriott, Sheraton Grand, and Hilton Chicago were all affected, as workers demanded higher wages, year-round health insurance, and sick days.
