The Union told Gaylord that they either sign an agreement obligating Gaylord to ONLY use Unionized Labor or if they didn’t the Union would sue Gaylord during the EIR process and do anything in their power to stop the project. Gaylord had already agreed to pay Union Labor wages but were refusing to be required to limit their bidding pool to only 20% of the contractor labor force in San Diego.
Also I am sure another developer will be found but you are forgetting the 2+ years of work Gaylord has invested in this project and worked with the City. A whole new agreement will have to be drafted, negotiated, etc. This will take years.
And those of you who are quoting it has to do with the current economic situation, this project would not be completed for YEARS. Whatever economic situation we see today will be at least partially corrected by then. Gaylord has a history of tacking big complex projects and has completely may successful ones. They just weren’t willing to fall prey to the Unions and called the Union bluff.
