The exodus of Hollywood awards ceremonies from the Century Plaza has continued, thanks to the hotel management’s involvement in a labor dispute.

The Visual Effects Society has become the latest to depart, switching the location of the 9th Annual VES Awards to the Beverly Hilton Hotel on Feb. 1, including presenting Christopher Nolan with the org’s inaugural Visionary Award. The event had been scheduled originally for Jan. 28 at the Century Plaza.

Other shows began moving two weeks ago due to Unite Here’s dispute with Hyatt management over the issue of organizing workers at nonunion hotels.

Shows that were moved include the Producers Guild of America to the Beverly Hilton on Jan. 22, the Directors Guild of America to Hollywood and Highland on Jan 29, the Writers Guild of America West to the Renaissance Hotel in Hollywood on Feb. 5 and the American Society of Cinematographers to Hollywood and Highland on Feb. 13.

Unite Here announced on Sept. 15 that Hyatt workers at three area hotels — the Century Plaza, the Hyatt Andaz West Hollywood and the Hyatt Regency Long Beach — had called for a boycott due to the dispute. The Intl. Cinematographers Guild announced around that time that its Publicist Guild Awards on Feb. 25 would be at the Beverly Hilton after holding this year’s event at the Century Plaza.

Unite Here picketed the Nov. 13 gala-auction for the L.A. Gay & Lesbian Center at the hotel, prompting that org to announce it wouldn’t return to the Century Plaza in 2011.
