UNITE HERE Local 25—which represents thousands of hotel, restaurant, and casino workers in Washington, D.C.—is calling on hotels in the region to shut down in advance of Biden's inauguration except for use by security personnel. 

After the January 6 Capitol riot, Local 25 requested all its members be evacuated from the downtown area. Benjy Cannon, a spokesperson for the union, told The Washington Post that “at least 12 hotels in the area either let employees leave early or stay overnight if they kept working.” Hotels in the region struggled that night and the days after with members of the mob who began to return after a 6 p.m. curfew was instituted.
