The hotel’s non-union workers, with the supported of L.A. hospitality labor union Unite Here Local 11, are demanding millions of dollars in alleged unpaid wages. In an announcement today, they allege two employees were fired in retaliation for activism.

“Days after I spoke up about working off the clock, I was called into the general manager’s office and asked why I was sabotaging the company. Then I was fired,” said Nicomedes Quiapos, a 15-year veteran bartender and restaurant server, in the union’s press release.

Hotel management could not be reached for comment on Thursday afternoon. In a Business Journal interview last week, hotel general manager Adrian Valencia said Holiday Inn LAX abides by the city’s living wage requirements and uses proper procedures in dealing with its workers.
