A union representing workers at the financially troubled New York City Opera says it will file unfair labor practice charges after the board voted to move out of the Lincoln Center and cut staff.

National Executive Director Alan Gordon said Saturday that the American Guild of Musical Artists will also consider seeking an injunction preventing the production company from continuing to use the name New York City Opera.

On Friday, the board voted to leave the Lincoln Center, cut staff across the board and scale back its performance schedule. The opera's general manager, George Steel, says the changes are necessary to keep the opera afloat and build "a foundation for sustainable growth."

The 68-year-old organization is revered as a pillar of American culture. But in recent years, it has been struggling with a dwindling endowment and a multimillion-dollar deficit.
