The Metropolitan Opera, which promised to match the pay cuts that its major unions agreed to last month with equivalent cuts to its nonunion payroll, said on Friday afternoon that it was eliminating 22 of its 254 administrative positions, mostly through layoffs.

The company said it had eliminated nonunion positions across the opera house, cutting jobs in its artistic, finance, marketing, development, and technical departments — through attrition in some cases, but primarily through layoffs.

“The reductions are part of an ongoing effort to make the 131-year-old organization leaner fiscally, but without diminishing the production values of its presentations onstage,” the Met said in a statement announcing the staff cuts.

The Met has struggled financially in recent years, with dwindling box office revenues and rising expenses leaving it more reliant on a small number of wealthy donors, and on its endowment fund, which it has tapped to cover operating costs. The Met’s board of directors said it would begin a campaign to double the Met’s endowment over the next five years if the company took steps to curb expenses.
