Employees of the Metropolitan Opera are being told to prepare for a possible strike or lock out.
An official with the American Guild of Musical Artists has sent a letter to the singers, dancers and production staff it represents.
It reads, "It would be prudent for all Met employees to anticipate and prepare for absence of Met income in the fall and winter of 2014, and perhaps even longer."
The opera’s contracts with the AGMA, as well as other contracts with orchestra performers and stagehands, all expire on July 31.
According to the union letter, the Met has said it will seek 10 percent or 15 percent reductions in compensation and other concessions.
The Met, meanwhile, responded by saying, "While negotiations have yet to even begin with the unions representing our employees and no proposals have been made, there are significant economic challenges that we face, including a recent decline in ticket sales - an unfortunate situation that we share with other opera companies across the nation."
